The Models 765M20 and 765M22 High Intensity Acoustic Sensors (Microphones) are designed for the measurement of gas-borne sound in industrial applications. These sensors have been constructed for use in corrosive environments that are compatible with the type 316 stainless steel diaphragm. The miniature 10-32 fused-glass coaxial connector, when combined with allwelded construction, provides a true hermetic seal.
Electrically, these devices comprise 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.
