Meggitt Sensing Systems Releases Endevco Model 8530B Transducer

By DE Editors

Meggitt Sensing Systems has announced the release of the Endevco model 8530B series, a family of miniature, high-sensitivity absolute piezoresistive pressure transducers, offering high-output measurement capabilities and thermal-transient stability in a 3.86 mm face diameter and 2.3-gram package.

Offered in ranges of 200, 500 and 1000 psia with 300 mV full scale output and high resonant frequencies of 750 kHz (200 psia) and 1000 kHz (500 and 1000 psia), the Endevco model 8530B series features an active four-arm strain gage bridge, diffused into a sculpted silicon diaphragm. The volume behind the diaphragm is both evacuated and glass sealed to provide an absolute pressure reference. The transducers also feature self-contained full hybrid temperature compensation, providing stable performance over a temperature range of 0°F to +200°F, according to the company.

Meggitt says Endevco model 8530B transducers are rugged to 20,000 g shock and minimum 4X burst pressure, and offer non-linearity, non-repeatability and pressure hysteresis errors of less than 0.50% FSO (200 and 500 psia versions) and 1% FSO (1000 psia version).

The Endevco model 8530B series comes standard with a 10-32 UNF-2A mounting thread (with optional metric M5X0.8 mounting thread available on special order) and integral cable.
