Model 377B01 Free Field 1/4” ICP™ Microphone

March 1, 2006, Depew, NY, USA – The Vibration Division of PCB Piezotronics, Inc. (PCB®) introduces Model 377B01 prepolarized, 1/4” Free Field response-type microphone which operates from ICP® sensor power. The distinguishing feature of this model is its enhanced frequency rating of 90 kHz (+/- 2 dB.) It has a sensitivity rating of 3 mV/Pa and a wide dynamic range (30 to 166 dB(A) re 20 µPa). This microphone has a 120 °C operating temperature range.

This model is one of a full series of modern, pre-polarized, condenser microphones and preamplifiers available from PCB. Powered by a 2 to 20 mA signal conditioner and standard coaxial cables, these modern designs allow for significant savings in power supply and cabling cost, greater ease-of-use and operate from the same power required for ICP® accelerometers. This provides the advantage of using microphones with ICP® accelerometers in the same test, with the same signal conditioning equipment, minimizing set-up time.
