Preamplifier Integrated Microphone TYPE 7146 (TYPE1)

SKU : #326

Sensitivity of 50 mV/Pa. Ideal for measurement situations where great accuracy is critical.
The “TYPE 7146” is a free-field 1/2-inch microphone with frequencies of 20Hz to 20 kHz.

Sound pressure sensitivity including the preamp is -27 dB ±2 dB re 1V/Pa (44.7 mV/Pa).
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
