New EX378B02 Microphone from PCB Piezotronics for Measurements in Hazardous Areas

PCB Piezotronics released a prepolarized condenser microphone system – Model EX378B02 – for use in hazardous areas. The new measurement 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.
