CRY371 Measurement Microphone - 1

CRY371 Measurement Microphone CRY371 measurement microphone is a pre-polarized 1/2 inch free field condenser microphone. It mainly used for measuring the real sound pressure of the microphone’s diaphragm. The microphone will affect the sound field and the high frequency sound field where the microphone is placed. Aiming at this problem, we change the frequency response of the microphone for adjusting to compensate the error caused by the high frequency sound pressure in the sound field. Features RY371 measurement microphone is a pre-polarized 1/2  Meet IEC 61094-4:1995 Measurement microphones―Part 4: Specifications for working standard microphones Meet GBT 20441.4-2006 Measurement microphones―Part 4: Specifications for working standard microphones Technique Specification Specification CRY371 Measurement Microphone Field Type Sensitivity mV/Pa (dBV/Pa) Frequency Response(dB) Polarity Voltage(V) Typical Capacitance Dynamic range limit(ref. 20uPa) ≥160dB (@250Hz THD<3%) Equivalent noise(ref. 20uPa) Working Temperature Temperature Coefficient Static Pressure Coefficient Relative Humidity Range Relative Humidity Coefficient CRY Sound Co., Ltd Add: No.31-1, Xianxing Road, Xianlin Industrial Park, Yuhang District, Hangzhou, Zhejiang
