Piezoresistive
Pressure Transducers Endevco Model 8530B
The Endevco Model 8530B is a miniature, high sensitivity
Piezoresistive Pressure Transducers for measuring absolute
pressure. The volume behind the diaphragm is evacuated
and glass sealed to provide an absolute pressure reference.
Full scale output is 300 mV with high overload capability
and high frequency response. It is available in ranges
from 200 psia to 1,000 psia. The Model 8530C is available
for lower pressure ranges.
Endevco Piezoresistive Pressure Transducers feature an
active four-arm strain gauge bridge diffused into a sculptured
silicon diaphragm for maximum sensitivity and wideband
frequency response. Self-contained hybrid temperature
compensation provides stable performance over the temperature
range of 0°F to 200°F (-18°C to +93°C). Endevco transducers
also feature excellent linearity (even to 3X range), high
shock resistance and high stability during temperature
transients.
The Model 8530B Piezoresistive Pressure Transducers have
been used successfully in many blast test situations.
For this application, a protective coating is recommended
to eliminate photoflash sensitivity and provide particle
impingement protection. This coating does not degrade
the superior dynamic response characteristics of the sensor.
The Model 8530B Piezoresistive Pressure Transducers are
available with Metric M5X0.8 mounting threads as 8530B-XXM5
on special order. Also available with integral four-pin
connector as Model 8530B-XXM37.
Endevco Model 136 Three-Channel System, Model 4430A Signal
Conditioner or Model 68207 BCAS™ Computer Controlled
Systems are recommended as signal conditioner and power
supply.
