The Endevco

model 8507C is a rugged, miniature, high sensitivity

piezoresistive pressure transducer. It has a 0.09 inch (2.3 mm)
cylindrical case and is available in ranges from 1 psi to 15 psi with
full scale output up to 300 mV. Its high sensitivity combined with
high resonance makes it ideal for measuring dynamic pressure.

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 excellent
stability during temperature transients.

The model 8507C is designed for installations which do not require
threaded mounting and 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 frequency makes the model 8507C ideal for use on
small-scale models in wind tunnels.

The Endevco model 126, 136, 4430A or 4990A (OASIS) are recommended as signal conditioner and

power supply.
