 The Endevco Model 8515C is a rugged, miniature, high
sensitivity piezoresistive pressure transducer available
in 15 and 50 psia full scale ranges. It is surface-mounted
and measures 0.030 inch thin bye 0.250 inch diameter (0.76
mm x 6.3 mm). Full scale output is 200 mV with high overload
capability, high frequency response, very low base strain
sensitivity and excellent temperature performance.
Because of its very small size, the Model 8515C can be
installed on curved surfaces with minimal effect on laminar
air or hot gas flow. For a flush fit, the 8515C and leadwires
can be recessed into the mounting surface. A protective
screen is provided to protect against particle impingement.
The Model 8515C is suitable for use on small-scale models
in wind tunnel tests as well as on aerodynamic surfaces
during flight tests. Other uses are for blast effect studies
and helicopter or turbine blade surface pressure measurements.
A rubber fairing, Part Number 30042, is an available accessory
for airflow smoothing for flight test applications. Modified
version are available on special order for wider temperature
compensation or with rectangular housings.
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:
• 15 to 50 psia, 200 mV full scale
