About the product

Preamplifier integrated microphone compatible with IEPE can be connected directly to FFT analyzer or other analyzers, enabling to measure with highly accurate resolution at low costs.
Long-term stability realized by accelerated aging process under 360℃ enables to use under 100℃ or higher.
Condenser microphone is to be used for measurements of sound presser level with high resolution over wide frequency range.
Varieties of microphone diaphragm diameter 1,1/2, 1/4, 1/6, 1/8 inch and corresponding frequency characteristics would best support measurements of various purposes.

Product Specifications

Wide frequency range
Wide range of measurement from low-frequency to ultrasonic frequency(1Hz~200kHz) is possible.

Wide dynamic range
Measurement of high sound pressure level up to 170dB is possible.

Preamplifier integrated microphone
It is also possible to connect directly to analyzer by using BNC cable.

For high sensitivity requirement
If high sensitivity is required, Type 7146/4152N20 offers 500 mV/Pa and it can measure from low sound pressure level..
It can be directly connected to equipment such as FFT Analyzer. and is easy to use.
