Miniature, high sensitivity transducer handles static and dynamic pressure
The Endevco model 8540 is a rugged, miniature, high sensitivity, piezoresistive absolute pressure transducer. It is ideally suited for flush mounting to measure skin pressures on aircraft, inlet distortion pressures in turbine engines, or transmission pressures in automobiles.
Designed to measure static or dynamic pressure, the model 8540's high frequency response permits use on small scale models in wind tunnels as well. The transducer has a 0.15 inch (3.8 mm) face diameter and is available in ranges from 15 to 500 psia. Its excellent linearity combined with very high resonance makes it ideal for measuring dynamic pressure.
The model 8540 employs silicon strain gages bonded to a micro-machined silicon diaphragm for maximum sensitivity and wide frequency response. Internal sensitivity compensation and zero trim provides accuracy to +500°F (+260°C). It can operate, with diminished lifetime, to +600°F (+316°C). This transducer exhibits low photo-flash sensitivity and high stability during temperature transients.
NOTE: The model 8540-200 is an Endevco Guaranteed In-Stock item.
