Measurement microphone CRY333-CRY507

surfacefrequency1/2"

Frequency response: 3.15 Hz - 20kHz Sensitivity: 50mV/Pa CRY333-CRY507 1/2" IEPE Free-Field Measurement Microphone Kit This kit consists of CRY333 Measurement Microphone and CRY507 IEPE Preamplifier self-developed by CRYSOUND, with a BNC port for output. CRY333 Measurement Microphone can also be combined with CRY510 to launch a kit. Stainless steel case High stability Wide range of applications Compliance with IEC 61094-4:1995 Measurement microphones - Part 4: Specifications for working standard microphones Compliance with G/BT 20441.4-2006 Measurement microphones - Part 4: Specifications for working standard microphones CRY333 Microphone is a 1/2'' pre-polarization free-field 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). The presence of the microphone in the sound field will affect the sound field and change its high-frequency sound field. Based on this characteristic, the free-field microphone has its frequency response adjusted to compensate for errors brought to high-frequency sound pressure in the sound field. This kit includes a CRY507 IEPE preamplifier which is powered by constant current source and featured by very high input impedance, very low noise floor, and a very wide frequency response range. It can be used with CRY300 series 1/2'' pre-polarization measurement microphones. The output interface uses a BNC plug, which can be easily connected to a professional measurement system. It is suitable for electroacoustic testers, multi-channel analyzers, noise analyzers and other instruments.
