A Preamplifier integrated microphone compatible with IEPE can be connected directly to an FFT analyzer or other analyzers, enabling measuring with highly accurate resolution at low costs.
Long-term stability realized by accelerated aging under 360℃ enables use under 100℃ or higher.
A condenser microphone is to be used to measure sound pressure levels with high resolution over a wide frequency range.
Varieties of microphone diaphragm diameters 1,1/2, 1/4, 1/6, and 1/8 inch and corresponding frequency characteristics would best support measurements of various purposes.
These measurement microphones’ diameters and electroacoustic characteristics comply with the international standard IEC 61094-4:1995.
It also complies with the microphone specifications required by IEC 61672, which is an important standard for measurement systems such as Class 1/ Class 2 sound level meters.
TYPE 1 and TYPE 2 indicate compliance with IEC 61672 Class 1 and Class 2, respectively.
