IMG-SAS

Ametek Solar Array Simulator (SAS)

sku Product SKU:  AME-SAS

A spacecraft solar array is subjected to large temperature excursions, varying insolation (the amount of sunlight falling on the array), mechanical changes and aging, which substantially effect both its short and long term performance. In order to test the spacecraft's power environment, a cost-effective solution for ground based testing is to utilize a solar array simulator.

The Elgar SAS system reproduces all possible solar array outputs, based on the wide variety of input conditions that an array faces, including orbital rotation, spin, axis alignment, eclipse events, beginning-of-life and end-of-life operation. The SAS also provides complete programmable control of all the parameters that shape the solar cell I/V output curve. By being able to accurately simulate solar panels under various space conditions with complete control, a system developer can comprehensively verify design margins and quickly test, in production, spacecraft power systems and their associated electronics.


Each Solar Array Simulator is a fully integrated, turn-key system complete with Windows NT graphical user interface and hardware control software. It can be remotely controlled and addressable as a single device when integrated into a customer's test system. This control is accomplished via a standard ethernet or optional GPIB interface using standard SCPI format commands.

As a very important consideration in spacecraft testing, discrete hardware protection systems are a standard part of every SAS. These include subsystems that can remove power at the output of the SAS in under 10 microseconds. Each SAS string has an electronic circuit breaker and relay disconnect, so faults are localized and minimize disruption of the last process. SAS systems have been designed and delivered ranging from desktop, 2 channel, R&D units to systems capable of controlling two 64 channel SAS systems simultaneously. AMETEK's Engineered Solutions Group can assist in defining special requirements and customize each system using a standard building block approach. This allows each customer to get exactly what id needed while minimizing costs.

Ametek Battery Sting Simulator (BBS)

sku Product SKU:  AME-BSS

The Elgar Battery String Simulators (BSS) provide safe, reliable battery power for spacecraft testing. The broad range of features available ensures simulation capabilities for more than just two terminal power. It's the ideal solution for complete integrated system testing, not just battery elimination.

The BSS behavior is determined by a charge table, in spreadsheet format, specific for a battery topology and various battery conditions. Many charge tables can be stored on the computer hard drive for easy retrieval.

The BSS operates in two modes, static and dynamic. In the static mode, when a state-of-charge value is entered, the BSS will instantly produce the terminal voltage corresponding to that state-of-charge. Because of this programmable flexibility, time consuming discharge cycles of flight test batteries are eliminated. In the dynamic mode, once a state-of- charge start point is entered, the BSS will monitor the charge and discharge energies being impressed on the "battery" and modify the terminal voltage accordingly.

Single or dual battery pack simulator versions are available with discharge currents of up to 150A and charge currents of up to 50A per battery. In addition, optional sensor simulators (including thermistor, pressure transducer, and heater loads outputs) allow closed loop input to the Spacecraft Power Regulator for true battery emulation. As with the SAS systems, each Battery Simulator System is a fully integrated, turn-key system using a Windows Graphical User Interface and hardware control software. This control is accomplished via a standard ethernet or optional GPIB interface using standard SCPI format commands.

Fluke Calibration 6109A / 7109A Portable Calibration Baths

sku Product SKU:  FCAL-6109A/719A

Now there are portable calibration baths (Fluke Calibration 6109A & 7109A) designed with the process manufacturing professional in mind. Process manufacturing plants for pharmaceuticals, biotechnology, and food production utilize many sanitary temperature sensors that require regular calibration. Production must stop during temperature sensor calibration. Therefore, more calibration throughput means less plant downtime. And in businesses where even a few tenths of a degree Celsius can cost thousands of dollars in ruined product, temperature accuracy is crucial to maintaining quality.

The Fluke Calibration 6109A and 7109A Portable Calibration Baths are liquid baths that let process industry professionals calibrate four times more sanitary sensors per batch in less time and with twice the accuracy of other portable baths in this class. Larger than micro baths, up to four tri-clamp sanitary sensors fit easily into these baths for calibration at ± 0.1 °C temperature display accuracy. Throughput is even higher for sanitary RTDs with small or no flanges.

Two bath models cover a wide temperature range: 35 °C to 250 °C for the 6109A and -25 °C to 140 °C for the 7109A. Each model offers a “-P” version that includes process electronics for connecting an external reference probe.

Professionals working in clean process industries, including facilities managers, production engineers and calibration technicians, prefer these baths for a variety of reasons.

Facilities managers need to meet U.S. FDA and ISO cleanroom standards like the baths’ stainless steel casing that stands up to harsh cleaning solutions. They depend on the 6109A and 7109A to help maintain the accuracy of the plant’s temperature sensors, thus reducing the possibility of an expensive product batch loss.

Production engineers also appreciate the baths’ accuracy, which helps them control sensor out-of-tolerance conditions. Moreover, they prefer to use a bath designed specifically for cleanroom calibration throughput. No more need to make do with equipment designed for some other application.

Calibration technicians who perform calibrations on platforms, in crawl spaces, and other hard-to-reach parts of the plant enjoy the portability and cleanroom compatibility (i.e. easy to sanitize, don’t harbour bacteria) of these baths.

Global Fluke Calibration service and support ensure that your 6109A and 7109A baths will give you years of service that you can trust.
