Sensors measure gas-borne sound in industrial applications
Units are designed for use in corrosive environments, and are electrically isolated.
New acoustic sensors (microphones) from Columbia Research Laboratories Inc. are designed for the measurement of gas-borne sound in industrial applications. Models 765M25 and 765M27 are constructed of Type 316 stainless steel for use in corrosive environments, are electrically isolated, and offer high sensitivity (1200 pC/psi) and temperature range from -10 to +500° F.
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. These come with a variety of connector and mounting options, all of which provide a true hermetic seal when combined with the all welded construction of the units.
The two models 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.

Annual Salary Survey
After almost a decade of uncertainty, the confidence of plant floor managers is soaring. Even with a number of challenges and while implementing new technologies, there is a renewed sense of optimism among plant managers about their business and their future.
The respondents to the 2014 Plant Engineering Salary Survey come from throughout the U.S. and serve a variety of industries, but they are uniform in their optimism about manufacturing. This year’s survey found 79% consider manufacturing a secure career. That’s up from 75% in 2013 and significantly higher than the 63% figure when Plant Engineering first started asking that question a decade ago.
