Meggitt Sensing Systems has debuted Endevco® model 8515C, a miniature, high-sensitivity piezoresistive pressure transducer, designed for surface air flow and other aerodynamic measurements requiring high output in a small, lightweight package.
The ultra-low profile design has an overall thickness of 0.76mm and diameter of 6.3mm. Units are available in ranges of 15 and 50 psia, with 200mV full scale output, and frequency responses of 180kHz and 320kHz. The transducers offer stable performance over an temperature operating range of -54 to +121°C, with combined non-linearity, non-repeatability and pressure hysteresis error of less than 0.50% FSO. In addition, model 8515C is designed to survive 10,000g shock and 10,000g acceleration, with minimum 5X burst pressure, making it the best performing transducer of its kind in the industry.
Model 8515C is supplied with integral cable, and 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 both transducer and lead wires into the mounting surface, while using a supplied protective screen to prevent particular impingement. For airflow smoothing within flight test applications, optional rubber fairing is available. Modified versions are available for wider temperature compensation. Model 8515C is well-suited for small-scale wind tunnel testing, helicopter or turbine blade surface pressure measurements, as well as flight test aerodynamic surface measurements.
