sku Product SKU:  AME-SGe S

The SGe is an economical, FET based, high switching speed, programmable, dc power supply alternative to SCR and IGBT based dc supplies.

Most topologies use either a MosFET or IGBT approach within their power stage to execute their power conversion topology. At the same time end users value low output ripple and noise in conjunction with achieving high slew rates. Both IGBT and SCR based designs typically run at much lower switching speeds requiring a larger LC output filter design for similar performance or require degrading ripple and noise performance in order to maintain competitive power densities. The filter design in this case may be balanced to trade off performance of response time with output ripple and noise and densities.

In contrast, our SGe line leverages the benefits of using high switching speed Mosfets requiring a much smaller output stage LC filter in order to provide competitive output ripple and noise performance and response time without compromising power densities. Available in two control versions, the SGe has basic analog controls, while the SGI provides intelligent control features

SGe: Real Value - Analog Control 
The SGe, with its outstanding FET based power electronics, is available for customers requiring simple front panel analog controls or external control. With high performance power electronics the SGe provides essential features like 10- turn potentiometers for setting voltage and current, 3½ digit LED readout plus front panel over-voltage protection (OVP) preview/adjustment and reset.

P5513 Pneumatic Pressure Comparator

sku Product SKU:  FCL-P5513

Pressure range 0 to 3,000 psi (210 bar)

This pneumatic comparison pressure comparator is designed for testing pressure measuring instruments against master test instruments. This cost effective instrument provides precise control for important calibration requirements and include many features found in our popular line of pneumatic deadweight testers.

Note: Unit requires pressure source (i.e. nitrogen bottle) for operation.

A pressure comparator supplies the same precisely controlled pressure to both a reference gauge and device under test for calibration. The Fluke P5513 is ideal for pneumatic calibration workload over 300 psi.

Make it a Pressure Calibrator (P5513-2700G)
The Fluke Calibration P5513 Pressure Comparator when combined with the 2700G Reference Pressure Gauges becomes an easy-to-use alternative to traditional deadweight testers that covers a wide range of workload. For convenience, the P5513 is bundled together with selected 2700G Reference Pressure Gauges for a complete bench top pressure calibration solution. These pressure calibrators provide the accuracy, reliability, and capability you need to calibrate dial gauges, digital test gauges and pressure transmitters.

For example, the P5513-2700G-3 is a P5513 Pressure Comparator, bundled together with 2700G-G20M, 2700G-BG7M, 2700G-BG700K. This calibrator has three pressure ranges corresponding to the three 2700G Reference Pressure Gauges in the bundle and covers a total pressure range of –12 psi to 3000 psi (–80 kPa to 20 MPa).

The accuracy of the calibrator is equal to the accuracy of the 2700G Reference Pressure Gauge being used: ±0.02% full scale of positive pressure or ±0.05% of full scale for vacuum.

5790B AC Measurement Standard

sku Product SKU:  FCL-5790B

The 5790B AC Measurement Standard is a multi-purpose ac measurement and transfer standard designed for the most demanding calibration applications. It combines the accuracy you would expect from a thermal transfer standard with the ease of use of a digital multimeter. Absolute ac voltage measurement uncertainties are as low as ± 24 ppm (one year, 23 °C ± 5 °C). The 5790B is designed to meet the complete ac voltage, ac current and wideband verification requirements of the Fluke Calibration 5735A, 5720A, and 5700A Multifunction Calibrators; 5522A, 5502A, 5520A, and 5500A Multi-Product Calibrators; plus other calibrators, amplifiers like the 52120, 5725A and 5205A/5215A, and transfer standards and ac voltmeters.

The 5790B covers an alternating voltage range of 600 μV to 1000 V, and a frequency range of 10 Hz to 1 MHz. Wideband voltage options extend frequency range to 30 or 50 MHz.

The 5790B in combination with the Fluke A40B Current Shunts now allow you to make direct, absolute or relative current measurements without the need to perform any calculations.

The 5790B may be used alone as a measurement device or as a transfer standard when compared to an external dc source. In either case the normally tedious switching and calculations are performed automatically by the 5790B, and the resulting ac/dc difference is displayed directly on the easy-to-read 6.5-inch full-color capacitive touch screen display.


Since its release in 1990, the 5790A has developed an unmatched reputation of being the most precise ac measurement standard in the industry. The technology behind the 5790A and the patented Fluke RMS sensor has made it the measurement standard of choice for calibration laboratories around the world. The 5790B retains the innovative technical features of its predecessor and adds many new capabilities and functions which expand the capable workload and reliability of the product.


The Fluke A40B series shunt resistors provide a very cost effective method to expand the 5790B’s functionality to measure absolute and relative ac current to calibrate an ac current source. The 5790B's new user interface allows you to input and save current shunts to its memory. Up to 150 shunts can be stored along with the shunts’ serial numbers, calibration constant values (24 ac/dc, five loading error points) and calibration dates. After the shunt information is loaded, the 5790B can be set up to take a direct absolute or relative ac current measurement within seconds by hooking up the shunt and simply selecting the appropriate shunt from the main menu. When using a current shunt, 5790B displays both the voltage and current measurements on the display along with the shunt information. Legacy Fluke A40 and A40A current shunts can be loaded and used to make relative current measurements.


The “/3” wideband input and function, with ranges of 2.2 mV to 7 V, 10 Hz to 30 MHz, is retained from the 5790A model. A new “/5” wideband option extends the bandwidth even further, to 10 Hz to 50 MHz. The expanded wideband range extends the workload of the product to calibrate precision 50 MHz power reference outputs found on most RF power meters.


A direct-readout-mode graphical user interface displays specifications for measuring common non-sinusoidal waveforms plus peak-to-peak computation (assumes THD <1 %.) This allows for instantaneous information when it is needed the most. Unlike the vacuum-fluorescent display on the 5790A, the new 6.5-inch capacitive touch screen display allows you to see more information on screen, reducing the need to switch between menus. The 5790B now specifies absolute dc voltage measurement uncertainties as low as ± 24 ppm (one year, 23 °C ± 5 °C), providing more confidence in transfer measurements. A dedicated special purpose 50 MHz, 225 mV, 50 ohm input function is available as an option for measuring RF power meter power reference outputs. The option is “spot calibrated” at the end of a precision level/phase stable metrology grade cable. It calculates the measured power with a 50 ohm load.


Statistics showing number of samples, standard deviation, average, min and max are calculated using the displayed readings as the basis. As a benefit of the large touch screen display, the statistics data can be viewed while the main measurement is still visible on the screen. The 5790B now does peak-to- peak waveform calculations for you. You can select one of four waveforms: sine, square, triangle, and truncated. Some of these waveforms are difficult and time consuming to calculate. The 5790B performs all the calculations for you based on the measurement, significantly reducing time and possible errors.


The graphical user interface features easy-to-read menus, as well as access to common functions with just the touch of a finger. Quickly select the range and input using the hard keys on the front panel. A bright red status indicator for HAZARDOUS VOLTAGE is located on front panel, letting you know immediately when hazardous voltage is present at the terminals. Like the new 5730A Multi- Product Calibrator, the front panel features Visual Connection Management™ terminals that light up to show you which terminals are active, guiding you to make the correct connections.


The 5790B is based on the patented Fluke Solid-State Thermal RMS Sensor, which has been proven since 1979 in a variety of Fluke products like the 792A AC/ DC Transfer Standard. The Fluke RMS Sensor is a true thermal converter, not an electronic converter that calculates the RMS value. Because its output voltage is 2 V rather than the 7 mV to 10 mV of traditional thermocouples, the RMS sensor exhibits excellent signal-to-noise characteristics and minimal reversal errors. With a higher output voltage, more accurate measurements can be made. And because of its small size, the RMS sensor stabilizes quickly and operates over a wide temperature range. The 5790B also features hermetically sealed thin-film resistor networks to minimize ac measurement errors and enhance temperature coefficient. The RMS sensor and thin-film resistor networks are designed by Fluke to be rugged and reliable. Each is built to exacting standards by the Fluke Microelectronics Group to maintain quality and consistency part after part.


The variety of inputs and connection types allows you to use the one that best suits your application. There are four sets of input terminals on the 5790B, two Type-N connectors and a set of five-way binding posts. One Type-N and one set of binding posts are dedicated to the ac measurement and transfer modes. AC or dc voltages may be applied to either input connection over the 5790B’s full range, allowing you to perform automated ac/dc transfer measurements. The 5790B determines automatically whether the applied voltage is ac or dc.

The second Type-N input connection supports the optional wideband mode. The input connection is easily selected with the touch of a key on the 5790B front panel. An LED indicates which terminals are active.

Whether you are using the 5790B as a voltmeter or a transfer standard, input voltage and frequency are always indicated on the measurement display. In the transfer mode, the ac/dc or ac/ac difference is always indicated on the control display in ppm, %, volts or ratio.

The 5790B is a fully autoranging instrument and it selects the best voltage range for the measurement you are making. You may also select and lock in ranges manually. Robust 1200 V input protection is active on all voltage ranges.

Using the trigger keys, the 5790B can switch from continuous to single measurements of the input voltage, making it easy to take sample readings at predetermined intervals.

When using the 5790B in transfer mode, the reference voltage is stored, and all ac/dc or ac/ac difference measurements are made relative to it. You may also store the average of two voltages as a reference to eliminate dc reversal errors, for example.

The intuitive front panel layout of the 5790B makes manual operation fast and simple. Keys and selections are logically arranged and labeled. And messages and menus are displayed clearly on the 5790B’s bright, touch screen display display.

USB, GPIB/IEEE-488, Ethernet and RS-232 interfaces are included and all functions of the instruments can be controlled by a PC. Using an available instrument driver, the 5790B can be integrated into automated systems operating with MET/CAL® Calibration Software.

molbloc-S Sonic nozzle calibration device

sku Product SKU:  FCL-molbloc-S


The mass flow rate through molbloc-S Sonic Nozzle is directly proportional to the upstream absolute pressure and independent of the downstream or differential pressure. molbloc-S flow ranges are defined by the molbloc's Pressure to Flow Conversion Ratio, KF. KF is expressed in units of sccm/kPa and defines the relationship between mass flow and the absolute upstream pressure delivered to the molbloc-S. molbloc-S calibrations are performed over flow ranges corresponding to either 20 to 200 kPa (3 to 30 psia), 50 to 500 kPa (7 to 70 psia) or 200 kPa to 2 MPa (30 to 300 psia) upstream pressure.

For flow measurements to be valid, the flow at the throat of the molbloc-S venturi nozzle must be critical, i.e. the gas speed is equal to the local speed of sound. Critical flow is achieved when a sufficiently low back pressure ratio, or BPR (molbloc-S downstream absolute pressure divided by upstream absolute pressure) is maintained. The upper limit of acceptable molbloc-S BPR values for critical flow varies between about 0.5 and 0.9 depending on the Reynolds number of the flow.

Since the mass flow through molbloc-S is proportional to the upstream absolute pressure, the flow range for this sonic nozzle calibration device in an application may be limited by the BPR limit. To maximize the range of a molbloc-S element, a vacuum pump can be connected downstream to reduce the downstream pressure while flowing. When the downstream pressure is kept sufficiently low, the upstream pressure, and thus the mass flow rate, can be adjusted all the way down to the minimum value for the molbloc's calibration type without being limited by the BPR. If molbloc-S will be used with atmospheric pressure downstream (no vacuum pump), then the molbloc can only be used over a range of upstream pressures starting at the maximum pressure for its calibration type down to a minimum pressure value at which the BPR becomes equal to the BPR limit at the current Reynolds number. molbox1 terminals include features to measure BPR, automatically alert the operator when the BPR is too high and prevent measurements when flow is not critical.


  • Covers ranges up to 5,000 slm in N2 and air
  • Useable with molbox1+, or existing molbox1 and molbox RFM mass flow terminals and COMPASS software

  • Excellent rangeability (10:1 turndown), with molbox1+S, or other molbox models with vacuum.
  • Redundant absolute upstream pressure measurement using both molbox absolute pressure transducers reduces uncertainty and increases reliability
  • Integral gas temperature conditioning and measurement
  • Continuous, real-time reading, as with traditional molbloc-L laminar element
  • Can be fully automated

Ametek XEL Series

sku Product SKU:  AME-XEL S

The Sorensen XEL benchtop power supply is as easy to use as simple analog power supplies but offers the flexibility of advanced digital features. The user interface allows easy control with single-turn knobs including a fine control knob for voltage.

This easy-to-use interface is complemented by V-Span, S-lock and Output Enable functions. V-Span allows the user to set a maximum and minimum value over which the knob control operates. This provides more precise control over the voltage as the knob operates over a narrow range as well as protecting devices under test by limiting the maximum voltage. S-Lock provides an easy method to output a regulated fixed voltage. Output Enable lets the user setup the desired voltage and current levels prior to actually turning on the output. All of these features in a laboratory bench supply are only found in the XEL series.

The programming "P" models include LXI Class C Ethernet, USB, RS-232 and analog remote control. The option "GP" inlcudes GPIB programming plus all of the interface methods included with the "P" models described above. This remote programming capability makes the XEL-P models well suited for system or ATE integration.

At 4.2x11.3 inches (108mm x 287mm), the XEL series occupies the least bench top space of any programmable power supply. The dual output model offers 90W per channel, also in a compact 8.4x11.3 inches (216mm x 287mm).

The dual output XEL30-3D is two 30V/3A power supplies in one unit. All of the features of the single output version are also in the dual output. The outputs are fully independent and isolated. Plus, the outputs can be operated in 4 modes: isolated, tracking, ratio tracking and true parallel. In addition, the outputs can be enable (on/off) independently or synchronously.

PG7202 High Pressure Gas Piston Gauge

sku Product SKU:  FCL-PG7202


  • State-of-the-art primary pressure standards for the lowest uncertainty levels
  • Unified solution from vacuum to 500 MPa
  • Outputs fully validated reference pressures in real time
  • Intuitive local operator interface
  • Manual, semi-automated and fully automated configurations

The PG7000 Series calibration standards are based on the fundamental principle of mass loaded onto a piston to apply a known force to a known effective area

Integrated piston-cylinder modules
Each PG7000 piston-cylinder is an integrated metrological assembly that includes the critical piston-cylinder mounting components. All of the mechanical parts that affect piston cylinder metrology are associated with the individual piston-cylinder, rather than being common parts of the piston gauge platform, enabling the user to:

  • Change ranges (piston-cylinders) in seconds, without using tools.
  • Handle and interchange piston-cylinders without exposing critical surfaces to contamination.
  • Protect the piston-cylinder from damage due to accidental shock or impact when handling.
  • Improve measurement reproducibility by avoiding frequent assembly/disassembly of mounting components.
  • Improve piston-cylinder mounting design by allowing each mounting system to be optimized for a piston-cylinder size and range.


Mass loading concentricity
The number of independent parts between the piston and mass load has been reduced to two—the piston cap and the mass loading bell. The piston head is effectively made part of the piston by machining it after installation concentrically to the piston within ± 20 microns.

Integrated electronics, software and remote interfacing
The electronics for monitoring all ambient and instrument conditions and functions are integrated into the PG7000 platform. RS-232 and IEEE 488 interfaces are included for remote communication. The system power supplies are also contained in the terminal to remove their heat source from the PG platform. For local operation, the user interacts with the PG7000 through a keypad and alphanumeric display on a compact terminal, allowing rapid, intuitive operation.

On-board measurement of operating conditions
PG7000 includes integrated on-board measurement of all the ambient and operating conditions needed to calculate pressure within tolerance, including relative humidity, barometric pressure, ambient temperature, piston-cylinder temperature, and reference vacuum.
Individual measurements can be observed in real time, both locally through the PG terminal and remotely over the RS-232 or IEEE 488 interface. Verification and recalibration of the on-board sensors is supported by embedded software.

Monitoring piston behavior
PG7000 measures and provides real time indication of piston position, drop rate, rotation rate, and rotation deceleration. Piston position is measured on the LVDT principle, with a ring on the inside of the mass loading bell acting as the armature. Rotation rate is measured optically by a sensor in the mounting post, which detects the movement of a notched ring on the inside of the mass loading bell. Both measurement systems are completely non-interfering, with no influence on the free movement of the piston in any axis.

Ready/not ready indication
The “ready/not ready indication provides the operator with a clear “go/no go indication of when an in-tolerance measurement can be made. It is based on testing for a variety of operating conditions, including piston position, piston fall rate, piston rotation rate, piston rotation deceleration, piston temperature rate of change and vacuum reference (when applicable). A ready condition is indicated when all conditions fall within specific limits. The limits for the various ready/not ready criteria can be customized by the user if desired.

Piston near-float detection
One of the most tedious aspects of operating a conventional piston gauge is adjusting pressure to float the piston. The piston lifts suddenly and without warning at the exact pressure corresponding to the mass loaded on the piston. Finding that point without overshooting requires slow and cautious pressure control.
PG7000 makes it easier to float the piston with a piston preloading system, which provides advance warning that the pressure is near the point where the piston will leave end of stroke. The preloading system only affects the piston when it is at end of stroke; it does not interfere with the free movement of the piston when it is floating.

Intelligent piston rotation
PG7000 is the first commercially available piston gauge to provide monitoring of rotation rate and decay in rotation rate. These measurements are used to assure that pressure readings are always made within limits. This relieves the operator of rotation rate monitoring responsibility and replaces subjective operator judgment with objective measurement.

Storage and shipping containers
The PG7000 piston gauge platform and mass set are packaged in heavy duty, weather proof, molded transit cases with custom inserts to provide optimum protection. PG7000 piston-cylinders modules are delivered in compact, virtually indestructible PVC bullet cases.

Advanced pressure generation and control components
All PG7000 pressure accessories are designed to increase the efficiency and ergonomics of piston gauge operation. These include manual, semi-automated and fully automated options to quickly and easily generate pressure and float the piston at the set point.

COMPASS® for Pressure calibration assistance software
COMPASS software sets up records for the units under test (UUT), defines and associates test procedures with UUTs, runs tests, acquires reference and test data, produces standard and custom calibration reports. All reference, UUT and test data is collected and stored in a database and standard delimited files. COMPASS can manage any kind of test from manual operator control and logging of test data to fully automated, unattended test execution.

A unified solution from vacuum to 500 MPa
The PG7000 line of piston gauges covers the complete range of pressure from very low absolute and differential in gas, up to 500 MPa (75 000 psi) in oil. While several piston gauge platforms and specialized accessories may be needed to cover different ranges and media, a consistent user interface and operational principles are maintained throughout the line. In most cases, complete gas and oil calibration capability can be achieved with just two PG platforms, four piston-cylinder modules and one mass set. Maintaining consistency from system to system makes them easier to learn and to use. Maintenance costs are reduced by minimizing the number of metrological elements to be supported.

PG7000 Piston Cylinder Modules
The piston-cylinder defines effective area and is the piston gauge's principal metrological element. The piston-cylinder's intrinsic characteristics and how it is mounted and exploited are the keys to piston gauge performance.

PG7000 piston-cylinders are manufactured by Fluke Calibration using proprietary production techniques that result in pistons and cylinders whose typical shape is within less than 0.2 micron from ideal geometry. Pure gas operated piston-cylinders use large diameters and very small annular gaps to minimize gas species and operating mode effects and to maximize piston float times. For example, the typical annular gap of a 35 mm gas operated piston-cylinder is less than 1 micron. Oil operated piston cylinders use small diameters to reduce the quantity of mass needed to cover the typical high pressure range.

All Type 7000 pistons and cylinders are made of tungsten carbide. Each PG7000 piston-cylinder is a complete, integrated metrological assembly that includes the critical piston-cylinder mounting components for improved metrological performance. All Type 7000 piston-cylinders use free deformation mounting systems in which the cylinder is allowed to deform under the influence of applied pressure, without O-rings or seals along the cylinder length. For higher pressure gas assemblies, a new mounting system, negative free deformation, applies the measured pressure uniformly along the full length of the cylinder. This reduces deformation under pressure, so piston drop rates remain low even at high operating pressures, while avoiding the unpredictable strain points of conventional reentrant designs.

PG7000 Mass Sets
Masses loaded on the piston are accelerated by gravity to apply a known force on the piston against which the defined pressure is balanced.

A PG7000 manual mass set is made up of main masses of 10 kg or 5 kg, fractionary masses in 5-2-2- 1 progression from 0.5 kg to 0.1 kg, and a trim mass set with masses from 50 kg to 0.01 g. Any desired mass value within the mass set range can be loaded to 0.01 g. All main and fractionary masses are machined from solid, nonmagnetic stainless steel and adjusted to their nominal values in the mass without cavities or trimming hardware which can reduce mass stability over time. Individual masses are comfortable to handle, with angled lifting surfaces on the edge of each mass and special mass trays that assist in orderly loading and unloading.

A PG7000 automated mass set is composed of main mass discs of 6.2 or 10 kg each and a set of tubular masses in binary progression from 0.1 to 3.2 or 6.4 kg. A pneumatically driven automated mass handling accessory (AMH) loads requested mass values in increments of 0.1 kg. The AMH and mass set are easily removed to access the piston-cylinder module when necessary.
