Kaidi KD-CCY11 Micro Differential Pressure Transmitter 4~20mA Protection Class Is Up To IP54 For HVAC And Air Conditioning

This series of differential pressure transmitters use piezoresistive pressure sensor chips, which use thin film resistors on the substrate to perform zero point correction, zero point temperature compensation and sensitivity compensation. Interference, stability and reliability. Therefore, the product can be used in various differential pressure occasions for gas measurement. It is an ideal differential pressure measuring instrument in the field of industrial automation.
