The Meggitt model 522M40 is a precision piezoelectric pressure transducer designed for sensing dynamic pressure fluctuations, even in extreme temperatures and high static pressure. The transducer is manufactured with all welded construction using high temperature Inconel. The model 522M40 operates at temperature extremes of up to 1300˚F continuous and up to 1500˚F intermittent (5 minutes over 30 minute period).

The integral metal-sheathed cable is of triaxial construction with a 10-32 coax receptacle which features output signal to case isolation. The electrical design is optimized for use with single-ended amplifiers. The integral hardline cable brings the connector end of the assembly into cooler environments.

Patented remote charge converter (Model 1772-X) makes it possible to use the sensor at almost twice the frequency band of the typical piezoelectric sensor.
