High Intensity Acoustic Sensors
Models 765M25/27 High Intensity Acoustic Sensors (Microphones) from Columbia Research Laboratories, Inc. are designed for the measurement of gas-borne sound in industrial applications. 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. 765M25/27 sensors are constructed of Type 316 stainless steel for use in corrosive environments. These units are electrically isolated and offer high sensitivity (1200 pC/psi) and temperature range from -10 to +500° F. This series offers a variety of connector and mounting options. All of them provide a true hermetic seal when combined with the all welded construction of the units.
The two designs of the 765M25/27 differ only in their electrical connections. The model 765M25 incorporates a miniature 10-32 fused-glass coaxial connector. Model 765M27 provides a 2-pin connector interface. Optimum performance is achieved when used with a true differential input amplifier.
Columbia Research Laboratories, Inc. is ISO9001:2000 with Design & AS9100 Revision B certified.
