Acoustic Measurement Microphones feature prepolarized design.
September 10, 2012 -
Consisting of microphone and preamplifier combinations, ¼ in. Models 378C01 and 378C10 measure frequencies to 100 kHz and amplitude to 165 dB. Free-Field Model 378C01 is suitable for automotive and aerospace noise source location and array applications, while Pressure Response Model 378C10 is typically used in noise absorption applications within impedance tubes, or general noise testing in cavities or small enclosures. Both are powered by 2-20 mA signal conditioner and standard coaxial cables.

PCB Piezotronics Introduces New 1/4" Acoustic Measurement Microphones
For High Amplitude and High Frequency Applications
Depew, NY- PCB Piezotronics, Inc., a global leader in the design and manufacture of microphones, vibration, force, torque, load, strain, and pressure sensors, as well as the pioneer of ICP technology is pleased to announcea new " prepolarized microphone series to complement its line of acoustic products. Models 378C01 and 378C10 are microphone and preamplifier combinations designed to measure very high frequencies and high amplitudes. The distinguishing features for this series are the microphone frequency capability, which can accurately measure to 100 kHz, and the amplitude range of 165 dB (re 20mPa), commonly referred to as the 3% distortion limit.
Model 378C01 is a Free-Field microphone and preamplifier making it suitable for automotive and aerospace noise source location and array applications. Other common applications include biological and medical acoustic analysis, machine monitoring and defect detection, gunshot analysis, cabin noise and other applications such as testing in anechoic chambers. Model 378C10 is a Pressure Response microphone typically used in noise absorption applications within impedance tubes, or general noise testing in cavities or small enclosures.
PCB carries a full compliment of prepolarized condenser microphones and preamplifiers. Powered by a 2-20 mA signal conditioner and standard coaxial cables, these modern designs are extremely popular due to significant cost savings in power supplies and cabling. The prepolarized designs can also be used with the same constant current source used for ICPaccelerometers, thereby minimizing set-up time. IEC 61094 compliant prepolarized condenser microphones are built around the ICP sensor technology that PCBinvented. PCB also offers the traditional externally polarized microphones that run off of a 200V power supply. All microphones are offered with a "Total Customer Satisfaction" policy.
