Specification Sheet- Pressure Tansducers.pdf

This is a Specification Sheet for commercially available pressure transducers required by the Government in a quantity of 54 units. The transducers must be designed to measure hydrogen pressure within a range of 25-2200 psi and operate in absolute or sealed gage modes. The devices shall withstand over-pressure conditions of 2x rated pressure and burst pressures up to 5x rated pressure with a maximum limit of 15,000 psi.

The equipment specifications include an electrical excitation rating of 8 to 32 VDC with a maximum current of 25 mA, full scale output of 4.0 VDC +/- 0.25 VDC, and total error band of +/- 0.25% FSO maximum. Additional performance requirements encompass an operating temperature range of -40°F to +265°F, compensated temperature range of -40°F to +250°F, linear vibration tolerance of 20g peak sine wave (10 to 2000 Hz), and mechanical shock resistance of 20g half-sine wave with 11-millisecond duration. The transducers must feature 100% relative humidity tolerance, infinitesimal resolution, insulation resistance of 100 megohms at 50 VDC, and output impedance of 750 megohm maximum. Physical specifications include a weight of 110 grams, pressure sensing principle utilizing a fully active four-arm Wheatstone bridge with dielectrically isolated silicon on silicon, mounting torque limit of 100 inch-pounds maximum, electrical connection via PTIH-10-6P connector or equivalent, and pressure port connection of 7/16-20UNJF-3A MS33656E-4. The requirement can be satisfied by Kulite manufacturer part number BME-76-1100 or an equivalent commercially available product.
