Brief introduction: MIC series products are designed to measure dynamic pressure, ultrastatic pressure and wind pressure in high temperature environments where ordinary micro speakers cannot work, and the sound pressure is standard in the dynamic range of 100 to 194dBA. The sensor is very robust and does not require special protection unless used in an environment where particles are contained in the airflow (e.g. wind tunnel, engine test room, etc.). Kulite can provide a variety of micro-silencer protectors. ● Low G sensitivity; ● Wide dynamic range; ● Multi-directional induction pressure; ● High static pressure; ● Small size; ● Steady-state response ability; ● Flat response
