 The Endevco Model 8511A is a rugged, piezoresistive
pressure transducer for high pressures. It has a 3/8-inch
mounting thread and is available in ranges from 5,000
to 20,000 psig.
Endevco 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 table performance over the wide temperature range
of 0°F to 200°F (-18°C to +93°C). Endevco transducers
also feature excellent linearity (even to 32X range),
high shock resistance, and high stability during temperature
transients.
The Model 8511A is widely used for high pressure applications
such as studies of structural loading by shock waves resulting
from explosive blasts, pulsations in hydraulic and combustion
systems. The Model 8511A is designed to operate in a gauge
mode, i.e., the back of the diaphragm is referenced to
atmospheric pressure. For harsh environments where there
is particle impingement, the 8511A-M1 version is available
with a protective screen and a black silicone grease coating
which further reduces photoflash sensitivity and provides
an effective thermal barrier for short duration high temperature
service.
Endevco Model 136 Three-Channel System, Model 4430A Signal
Conditioner, or Model 68207 BCAS™ Computer Controlled
System are recommended as signal conditioner and power
supply.
Features:
• 5,000 to 20,000 psi
