Brief introduction: MIC series products are designed to measure dynamic pressure, superstatic pressure and wind pressure in high temperature environments that cannot be operated by ordinary microspeakers, 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 except in environments where particles are contained in the air flow (e.g. wind tunnels, engine test booths, etc.); Kulite can provide a variety of microphonic protective screens. ●Low G sensitivity; ●Wide dynamic range; ●Multi-directional induction pressure; ● High static pressure; ●Small size; ●Steady-state responsiveness; ● Flat response

KulitefirmMICThe series of products is designed to measure the dynamic pressure, superstatic pressure and wind pressure in high temperature environments that cannot be operated by ordinary microsounders100arrive194dbaDynamic range is standard. The sensor is very robust and durable, unless used in environments where particles are present in the air flow(Such as wind tunnel, engine test room, etc)In addition, no additional special protection is required;KuliteVarious microspeaker protective screens can be provided.
