Application Briefs

Emerging Technologies, LLC. was called upon to develop a test system for electrically operated air pressure based products. The new system was to be based on an existing system re-using some of the existing components. New components were used where higher accuracies were required. Additionally, the new system was expected use a smaller enclosure requiring less space in the lab.

Emerging Technologies, LLC. was called upon to build a duplicate system to one previously provided by Emerging Technologies. Additionally, the system required the integration of a three-phase AC power source for testing three-phase product. The new three-phase panel is mobile for use with the automated test system (via GPIB interface) or elsewhere under manual control.

Emerging Technologies, LLC. was called upon to develop a test system for electrically operated air pressure and flow based products. Accurate measurement of flow, pressure, vacuum, temperature, and barometric pressure of air with correction to standard flow was required. Additionally the system required control of AC voltage and frequency, DC voltage, as well as, metering of voltage, current, frequency (AC only) and power. Noncontact shaft speed measurement was also required. All metered values are stored to disk based on operator input via a National Instruments LabView 7.0 interface.

Emerging Technologies, LLC. was requested to design and build an automated compressor test system for pressure,flow, power and speed that included an integral synchronized burn-in routine. The system automatically controls back pressure to 100PSIG at flowrates of air up to 1.75 SCFM. The system was also required to manually check max vacuum up to 30”Hg. The system monitors barometric pressure, and ambient temperatures. It required a single flow meter for the pressure circuit to allow for the accuracy required for testing across the product ranges. A single auto-backpressure regulator was used to allow for the pressure control accuracy.

Emerging Technologies, LLC was called upon to add functionality to a test system design for electrically operated air pressure and flow based products. In addition to the functionality of the existing Engineering Test System, new features included computer-controlled pressure and motor speed and an automated testing sequence that would remove user interaction required for numerous tests. The control for the added functionality was added to the
current user interface.

Emerging Technologies was called upon to develop a multi-product custom pump test system for the functional test of fractional horsepower compressor pumps. This system included many features seen before in Emerging Technologies’ test systems. Pressure, vacuum, volts, watts, amps and duration are automatically tested against the configurable test sequence and specification. This specific test system is capable of testing a wide range of AC and DC voltage product. Additionally, the system monitors and records key specification points. Some compressor applications require the capability to start against pressure. As the test system monitors the DUT pressure, the test program cuts power at the specified PSIG for a pass/fail result. This test verifies the DUT can start against pressure without the need to exhaust all existing pressure in the system. Test results are stored locally on the system PC hard drive. A test report for each unit tested is added to an easy to read file allowing the manufacturer and/or customer to review each individual DUT’s results post test. The database of results is required to identify trends and fluctuations in manufacturing quality.
