CRY334 Measurement microphone

Pressure field type; pre-polarization; frequency range: 3.15 Hz - 10 kHz; sensitivity: 50 mV/Pa; dynamic range: 15-146 dB

CRY334 Microphone is a 1/2'' pre-polarization pressure-field type measurement microphone that measures the actual sound pressure on the surface of the microphone diaphragm (including changes in the sound field due to the presence of the microphone itself).
