Meggitt Sensing Systems has introduced the Endevco® model 8530C series, a family of high-sensitivity piezoresistive absolute pressure transducers, offering high output and a non-linearity of 1% at 3x over-range in a highly compact (3.86 mm face diameter) package. The unique design and performance characteristics of this series make them ideal for use in hydraulic and pneumatic pressure measurements, automotive airbag testing and transmission testing applications.
Offered in ranges of 15, 50 and 100 psia with 225 mV full scale output and high resonant frequencies of 180 kHz (15 psia), 320 kHz (50 psia) and 500 kHz (100 psia), the Endevco® model 8530C series features an active four-arm strain gage bridge, diffused into a sculpted silicon diaphragm, for maximum sensitivity and wideband frequency response. The volume behind the diaphragm is both evacuated and glass sealed to provide an absolute pressure reference. The transducers also feature integral temperature compensation, providing stable performance over a temperature range of -18°C to +93°C (0°F to +200°F). Units are supplied with an integral cable, with custom lengths available upon request. A 10-32 UNF-2A mounting thread is standard, with an integral four-pin connector available with the “M37” option.
Endevco® model 8530C series transducers are rugged to 20,000 g shock and offer an industry best-in-class minimum 4X burst pressure, with non-linearity, non-repeatability and pressure hysteresis errors of less than 0.50% FSO for all ranges, making it one of the industry’s most accurate pressure transducer series. Recommended accessories include the model 136 three-channel signal conditioner, model 4430A signal conditioner, or model 4990A (Oasis).
