Depew, NY, USA ‚– The Automotive Sensors division of PCB Piezotronics (PCB‚®) releases the industry‚’s first IEC-compliant high temperature acoustic measurement system. The model 378B02, a combined prepolarized ICP‚® microphone and preamplifier, allows for high temperature automotive acoustic testing to +120 ‚°C, eliminating the need for high-priced probe microphones. This model also incorporates TEDS technology, allowing for larger channel count testing applications, with greater calibration data storage and retrieval capability and minimized setup time.
Use of traditional ICP‚® prepolarized microphones for reliable measurements in high temperature areas of a vehicle, including underhood, engine, manifold, exhaust pipe and other hot spots, has traditionally not been possible, due to temperature limitations of standard microphone preamplifiers. While ICP‚® microphones have standard operating temperatures to +120‚°C, microphone preamplifiers could not reliably perform at temperatures beyond their own standard operating temperature of +70 ‚°C. With the extended acoustic measurement temperature range offered by Model 378B02, the entire acoustic measurement system can now survive the same temperature range as an ICP‚® microphone. The added inclusion of Transducer Electronic Data Sheet (TEDS) technology capability allows larger channel count testing and greater calibration data storage and retrieval.
