Low profile Pressure Transducer for aerodynamic testing.
Endevco's Model 8515C piezoresistive pressure transducer
is now available with a double paralene coating that protects
against temporary water impingement.
The coating is applied to the diaphragm and interfacing components
between the case and diaphragm. This rugged, high-sensitivity transducer
is ideal for blast effect studies and the measurement of surface pressure
gradients on helicopter or turbine blades. The Model 8515C is also
well-suited for flex circuit applications on aerodynamic surfaces during
flight tests, or on small-scale models in wind tunnel tests.
Available in 15 and 50 psia full-scale ranges, the Model 8515C features
full-scale output of 200 mV with high overload capability, high frequency
response, very low base strain sensitivity, and excellent temperature
performance. Additionally, the transducer's miniature size facilitates
installation on curved surfaces with minimal effect on laminar air or
hot gas flow. For a flush fit, the Model 8515C and lead wires can be
recessed into the mounting surface. A protective metal screen protects
against particle impingement, moisture intrusion and incident radiation.
Optional accessories include a rubber fairing for airflow smoothing
during flight test applications. Modified versions of the Model 8515C
are available on special order for wider temperature compensation
or with rectangular housings. Endevco's Model 136 Three-Channel
DC Amplifier, Model 4428A or Model 4430A Signal Conditioner
are recommended as signal conditioner and power supply.
