GP:50 Corp. announces flight-qualified pressure transducers

October 10, 2014. GP:50 Corp., an ISO9001 certified designer and manufacturer of static pressure-sensing instrumentation, today announced the global-market introduction of the Model 7300, a rugged, flight-qualified, differential pressure transducer for aerospace and defense testing requirements.

The transducer is environmentally tested for conformance to MIL-STD-810F and meets J-001/NASA 8739.3 soldering workmanship standards. Units feature 316 stainless-steel housings and 17-4 PH stainless-steel wetted parts. Optional Inconel, Hastelloy, and Monel wetted materials are also available to accommodate a wider range of media. As the transducers feature no internal oil fill, they are also suitable for high-accuracy in-flight differential pressure measurements.

The compact Model 7300 measures 2.64” x 1.10” x 3.3” (67 mm x 28 mm x 83 mm) and weighs less than eight ounces (0.2 kg). The transducer operates over a standard measurement range of 15 thru 15,000 PSD (1 thru 1,034 BAR), with option to extend upon request. Overall measurement accuracy is <±0.3% FSO (RSS). Burst and proof pressure is 22,500 PSI (1,551 BAR).  Standard output configurations include 4-20 mA, 0-5 VDC, 0-10 VDC, and mV/V. An optional integral RTD temperature output is also available. Units are designed to reliably operate over a standard temperature range of -20°F to +190°F (-23°C to +82°C), with a compensated temperature range from -10°F to +190°F (-23°C to +82°C). Each transducer is supplied with NIST-traceable calibration to ANSI-Z540-1.

With its small, rugged design and high accuracy, the Model 7300 is suitable for fuel-flow monitoring and control; hydraulic systems pressure monitoring; filter condition monitoring; commercial and defense satellites; unmanned aerial vehicle (UAV) testing; aircraft engine testing; in-flight differential pressure measurements; and launch vehicle testing.
