June 5, 2018, Depew, NY – PCB Piezotronics, Inc. released a prepolarized condenser microphone system – Model EX378B02 – for use in hazardous areas. The new microphone system is compliant with explosive atmospheres and gaseous hazardous environments where standard microphones are restricted. Additionally, EX378B02 is compliant with intrinsic safety protection levels for all above ground applications globally; below ground very high (Ma) mine safety protection levels for all mining locations outside of North America; and below ground Mine Safety tests in Europe.

The EX378B02 is equipped with a free-field microphone cartridge. Featuring an industry-exclusive design, it has a frequency range of 3.75 to 20,000 Hz. With the low-end noise-floor measurement capability of 15.5 dBA, it can measure accurately to 137 dB at the top end. The extended range makes this acoustic measurement system an excellent choice for leak detection, gas tank testing, oil rig and machinery monitoring applications in areas where spark prevention is critical.

This EX378B02 microphone system is available for immediate shipment. Visit www.pcb.com for additional information or contact Mark Valentino, PCB Product Marketing Manager, at (800) 828-8840 x2134 or mvalentino@pcb.com.
