Meggitt Sensing Systems has announced the Endevco model 8515C, a miniature, high-sensitivity piezoresistive pressure transducer.

The transducer is designed for surface air flow and other aerodynamic measurements requiring high output in a small, lightweight package.

The ultra-low profile design of Endevco model 8515C has an overall thickness of 0.030in (0.76mm) and diameter of 0.250in (6.3mm).

Units are available in ranges of 15 and 50psia, with 200mV full-scale output and frequency responses of 180 and 320kHz, respectively.

The transducers offer stable performance over a temperature operating range of -65 to 250F (-54 to 121C), with combined non-linearity, non-repeatability and pressure hysteresis error of less than 0.50 per cent FSO.

In addition, model 8515C is designed to survive 10,000 g-shock and 10,000 g acceleration, with minimum 5X burst pressure.

Model 8515C is supplied with an integral cable and is typically surface mounted onto curved surfaces, for minimal effect on laminar air or hot gas flow.

A flush-mounted fit may also be achieved by recessing transducer and lead wires into the mounting surface, while using a supplied protective screen to prevent particular impingement.

For airflow smoothing requirements within flight-test applications, an optional rubber fairing is available.

Modified versions of model 8515C are also available for wider temperature compensation.

All units are shipped in electrostatic discharge (ESD) packaging, for added protection during product shipment and handling.

Because of its high overload capability, high-frequency response, low base-strain sensitivity and temperature performance, model 8515C is suited for small-scale wind-tunnel testing models, helicopter or turbine-blade surface-pressure measurements, as well as aerodynamic surface measurements required during flight test.
