Fluke 710

sku Product SKU:  FLK-710

PRODUCT OVERVIEW: FLUKE 710 MA LOOP VALVE TESTER

Smart Control Valve Testing is now easier than ever

The Fluke 710 Valve Testing Loop Calibrator is designed to enable users to perform quick, easy tests on HART smart control valves. Featuring built-in test procedures and an intuitive user interface, the 710 allows users to quickly and easily perform valve tests, while the valve test quick-check results provide at-a-glance diagnostics help you make maintenance decisions faster than ever. The valve health quick-check results let you know whether your valve is in good, marginal or in bad operating condition so you can quickly decide whether additional maintenance is necessary.

Valve testing and HART communication in a precision loop calibrator

With the 710 Valve Testing Loop Calibrator’s built in HART communication function, users can source a 4-20 mA signal to cause the smart control valve to move, while simultaneously interpreting the valve’s HART feedback signal to determine whether the valve is moving to the expected position. In addition to positional information, the measured pressure delivered from the valve’s internal I/P (which moves the valve) can be determined through the HART communication protocol.

The 710 has built-in test procedures that automatically increase and change the mA signal while monitoring the HART position and pressure feedback from the control valve, giving you a better overall picture of valve health at the simple push of a button.

Pre-configured valve tests, at-a-glance answers

Valve test routines built into the 710 include:

  • Manual testing; manually change the mA signal and view the HART position and pressure variable information
  • Full range ramping of the mA signal from 4 to 20 to 4 mA while recording the 0-100-0% position, or the pressures applied that move the valve from 0-100-0%
  • Stepping the mA signal on the input to the valve in steps and evaluating the valves response to the mA input changes
  • Speed tests to determine how fast the valve can open or close
  • Bump and partial stroke tests that help test valves over a portion of their range so they can be tested in a live process

ValveTrack™ Software enables further analysis and trending

Valve tests that are logged and recorded to memory in the 710 are available to upload to included ValveTrack™ analysis software.

ValveTrack™ software enables you to:

<ul">

  • Upload, print and plot logged valve tests taken in the field

molbox RFM Reference Flow Monitor

sku Product SKU:  FCL-molbox RFM

molstics provide a quick connector input for convenient connection to the gas supply. This is followed by a 2 micron (0.5 micron for low flow) filter to protect the downstream components. Then, an adjustable regulator sets and regulates optimum molbloc upstream pressure and protects the molbox transducers against accidental overpressure. The regulator range supports all standard molbloc operating pressure ranges. A bellows shut-off valve, just before the molbloc, allows the gas supply to be shut-off for configuration changes and/or system leak checking.

Special cradles support the molbloc(s). A connection and pads are provided downstream of the molbloc for mounting the MFC (mass flow controller), another device under test, or the optional metering valve kit for manual flow control.

Single channel molstics are available to accommodate single molblocs. Dual channel models allow two molblocs to be mounted simultaneously to switch between two different molbloc ranges without changing hardware or to take advantage of molbox1+'s capability to run two molblocs in parallel.

There are low, mid and high flow versions of molstic. Low flow molstics use a unique, very high stability pressure regulator and minimize dead volumes. They are required for effective use of 2E2-L and lower molblocs and can be used up to the 1E3-L molbloc size. The mid flow molstics cover the ranges of all the molblocs from as low 2E2-L up to the 3E4-L. The high flow molstic is required for the 1E5-L (100 slm) molbloc and supports that molbloc only.

Fluke Calibration E-DWT Electronic Deadweight Tester

sku Product SKU:  FLK-E-DWT

E-DWT-H breaks new ground, improving the hydraulic pressure calibration process. E-DWT-H is an electronic calibrator designed to replace mechanical, piston-cylinder and weight based deadweight testers. It’s a lighter, easier-to-use deadweight tester alternative that is at home in the lab or instrument shop, as well as in the field performing in-situ calibrations and tests. This complete hydraulic pressure calibration system combines the convenience and precision of continuous, realtime electronic pressure measurement with the simple and direct operation of high quality operator controlled pressure generation hardware. E-DWT-H one year measurement uncertainty is ± 0.02 % of reading with ranges up to 30,000 psi. It can be configured to provide this uncertainty from its full scale down to 1 % of its range. Built-in pressure generation and control hardware allow the operator to fill and prime the system under test and generate and precisely adjust pressure throughout the range with ease.
