Piezoresistive
Pressure Transducer Endevco Model 8530C
The Endevco Model 8530C is a miniature, high sensitivity
piezoresistive pressure transducer for measuring absolute
pressure. The volume behind the diaphragm is evacuated
and glass sealed to provide an absolute pressure reference.
Full scale output is 225 mV with high overload capability
and high frequency response. It is available in ranges
from 15 psia to 100 psia. The Model 8530B is available
for higher pressure ranges.
Endevco pressure transducers feature a four-arm strain
gauge bridge ion implanted into a unique 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 8530C has 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 8530C is available with Metric M5X0.8 mounting
thread as 8530C-XXM5 on special order. Also available
with integral four-pin connector as Model 8530C-XXM37.
Endevco Model 136 Three-Channel System, Model 4428A or
4430A Signal Conditioner or OASIS 2000 Computer-Controlled
System are recommended as signal conditioner and power
supply.
