The Model 567M7 High Intensity Acoustic Sensor (Microphone) is designed for the measurement of gas-borne sound in industrial applications. The sensor was designed for use in corrosive environments that are compatible with the type 316 stainless steel diaphragm. Model 567M7 incorporates a 2-pin MIL-C-5015 connector interface. When combined with its all-welded construction, the sensor provides a true hermetic seal.

Electrically, this device comprises sensing elements of piezoceramic material in a balanced and floating configuration to provide enhanced rejection of electrical noise associated with many industrial environments. Optimum performance is achieved when used with a true differential input amplifier. Consult the factory for customized versions of this sensor.

With Connector Mated or Protected, Unit is Hermetically Sealed.
