Piezoresistive
Pressure Transducer Endevco Model 8541
The Endevco Model 8541 is a rugged, miniature, high
sensitivity piezoresistive absolute pressure transducer.
The transducer has a 0.15 inch (3.8 mm) face diameter
and is available in ranges from 15 to 500 psia. The Model
8541 features high temperature performance to +662°F (+350°C)
continuously and can operate with diminished lifetime
to +750°F (+400°C). Its excellent linearity combined with
very high resonance makes it ideal for measuring dynamic
pressure in high temperature environments.
The transducer employs silicon strain gauges bonded to
a micro-machined silicon diaphragm for maximum sensitivity
with wide frequency response. Internal sensitivity compensation
and zero trim provides accuracy to +662°F (+350°C). This
transducer exhibits low photoflash sensitivity, high stability
during temperature transients and a particle screen protects
against debris.
The Model 8541 is designed to measure static and dynamic
pressures. Its small diameter is ideal for flush mounting
in gas turbine engines, measuring skin pressures on aircraft,
exhaust pressures in automobiles and other high temperature
pressure measurements. The transducer's high frequency
response permits use on small scale models in wind tunnels.
