Designed to measure static or dynamic pressure in a variety of high-temperature applications, the 8540 Series piezoresistive absolute pressure transducers from Endevco Corp. , San Juan Capistrano, CA, use a piezoresistive MEMS sensing element in a rugged SS case. F.S. output is to 300 mV. Internal sensitivity compensation and zero trim provide accuracy to 260°C with diminished lifetime operations in temperatures to 316°C. Sensors exhibit low photo-flash sensitivity, high stability during temperature transients, and are offered in measurement ranges from 15 to 500 psia. The 0.15 in. dia. sensor face facilitates flush mounting for skin pressure measurements on aircraft; inlet distortion pressures in turbine engines; or transmission pressures in automobiles.
