Preamplifier Integrated Microphone TYPE 4158N (TYPE1)

SKU : #329

Frequencies between 20Hz and 100kHz. Ideal for ultrasonic measurement.
The “TYPE4158N” is a free-field 1/4-inch microphone with frequencies of 20Hz to 100 kHz.

Sound pressure sensitivity including the preamp is -50 dB ±3 dB re 1V/Pa (3.2 mV/Pa).
Since this microphone is compact, impact caused by reflection or diffraction is minimal, and its sound pressure sensitivity is 3.2 mV/Pa. Thus, it’s also suitable for measurement with loud sound pressure.

Since this product is IEPE compatible, it can be connected directly to devices supplying constant current, such as FFT analyzers or AD converters.

【Features】
●With a BNC cable, connects directly to analytic devices such as FFT analyzers
●Low-cost measurement with great accuracy
●Long-term stability assured by applying pre-aging process of heating it to a high temperature of 360°C
