Meggitt Sensing Systems Introduces New Pressure Transducer

By DE Editors

Meggitt Sensing Systems has released the Endevco model 8515C, a miniature, high-sensitivity piezoresistive pressure transducer designed for surface airflow and other aerodynamic measurements requiring.

The low-profile design of Endevco model 8515C has an overall thickness of 0.030 in. (0.76mm) and diameter of 0.250 in. (6.3mm). Units are available in ranges of 15 and 50 psia, with 200 mV full-scale output, and frequency responses of 180 kHz and 320 kHz, respectively. According to the company, the transducers offer stable performance over a temperature operating range of -65 to +250°F (-54 to +121°C), with combined non-linearity,  non-repeatability, and pressure hysteresis error of less than 0.50 percent 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.  For airflow smoothing requirements within flight test applications, an optional rubber fairing is available.
