Microphone offers frequency range to 16 kHz.
Press Release Summary:
Operated from ICP® sensor power, Model 377A20 prepolarized, ½ in. Random Incidence (Diffuse Field) microphone has dynamic range of 14.6-146 dB(A) re 20 µPa. It can be used with ICP® accelerometers in same test, with same signal conditioning equipment to minimize set-up time. Power is provided by 2-20 mA signal conditioner and standard coaxial cables. It has +150°C operating temperature range and coefficient for temperature of -0.001 dB/°C.
Original Press Release:
New Model 377A20 Random Incidence ½" ICPTM Microphone Offers Extended Frequency Range
January 23, 2006, Depew, NY, USA - The Vibration Division of PCB Piezotronics, Inc. (PCB®) introduces Model 377A20 prepolarized, 1/2" Random Incidence (Diffuse Field) microphone, which operates from ICP® sensor power. The distinguishing feature of this model is its extended frequency range to 16 kHz (+/- 2dB). It has a sensitivity of 50 mV/Pa and a wide dynamic range (14.6 to 146 dB (A) re 20µPa). This microphone has a +150 °C (+302 °F) operating temperature range and coefficient for temperature of -0.001 dB/ °C.
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.
