PCB Piezotronics launches new ICP® array microphone offering water and dust resistance

PCB^® has launched a new pre-polarised microphone for harsh environments and applications such as automotive brake and tyre noise testing. The model 130A24 is a ½in (12mm) free-field polarised array microphone and preamplifier system with replaceable water and dust resistant cover.

The 130A24’s acoustically transparent cover provides an unobtrusive alternative to windscreens and a more consistent response compared to rubber protective covers often used in the harsh environments for which this microphone is ideal. The 130A24 features a wide dynamic range to 143dB with a rugged stainless steel grid cap

Specifications include frequency range to 16kHz, sensitivity of 10mV/Pa and operating temperature range from -10 to +50°C. Model 130A24 is an ICP^® sensor requiring constant current supply and can use an existing ICP^® power supply.
