Product Overview
IN66 series is a micro differential pressure transmitter developed for HVAC system. The product design has solved the fatal problems of micro pressure sensor such as zero drift, temperature drift, vibration drift to the greatest extent, and its reliability and stability are unique among micro differential pressure sensors. In the application process, the micro differential pressure indication is stable, the fluctuation degree is extremely small, and the precision is high. It is an ideal choice for HVAC automatic control engineering.
