MODEL
8534A
DESCRIPTION
The ENDEVCO^® Model 8534A is a rugged, subminia-
ture piezoresistive pressure transducer for measuring
absolute pressure. It has a case diameter of only 0.065
inch (1.65 mm) and is available in ranges from 10 to
100 psia full scale. Full scale output is 300 mV with high
overload capability and high frequency response.
ENDEVCO pressure transducers feature an active four-
arm strain gage bridge diffused into a sculptured silicon
diaphragm for maximum sensitivity and wideband
frequency response. Self-contained hybrid temperature
compensation provides stable 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 3X range), high shock resistance, and high
stability during temperature transients.
The Model 8534A can be installed in locations which are
difficult to reach. Its small size permits flush mounting on
curved surfaces. Its high sensitivity combined with small
size and high resonance makes the 8534A suitable for use
on small-scale models in wind tunnels.
ENDEVCO Model 136 Three-Channel System, Model
4430A Signal Conditioner, or Model 68207 BCAS™
Computer Controlled Systems are recommended as sig-
nal conditioner and power supply.
