Endevco's 8540 miniature piezoresistive pressure transducers measure absolute static or dynamic pressure

Endevco Corporation has announced the availability of the 8540 series, a family of rugged, miniature high-sensitivity piezoresistive absolute pressure transducers. The transducers' linearity and high resonance makes them well suited for measuring static or dynamic pressure within a variety of high-temperature applications.

Endevco 8540 series transducers employ piezoresistive MEMS technology housed in a rugged stainless steel case for maximum sensitivity and wide frequency response with a full scale output to 300 mV. Internal sensitivity compensation and zero trim provide accuracy to +500°F (+260°C) with diminished lifetime operations in temperatures up to +600°F (+316°C). In addition, the transducer series exhibits low photo-flash sensitivity and high stability during temperature transients. Available in ranges from 15 to 500 psia, the 8540 series features a small (0.15-inch; 3.8-millimeter) face diameter, which facilitates flush mounting for skin pressure measurements on aircraft, inlet distortion pressures in turbine engines or transmission pressures in automobiles.
