Decription of HVAC differential pressure transmitter used in commercial buildings and public transport hub

HVAC differential pressure transmitter used in commercial buildings and public transport hub is suitable for differential  pressure measurement of dry gas. It is the responsibility of the operator to verify that the equipment is suitable for the operating conditions of the application. If you have any questions, please contact our sales department to ensure the correct application of the transmitter. The company will not take any responsibility for the impact caused by improper selection.
HVAC differential pressure transmitter used in commercial buildings and public transport hub adopts piezoresistive pressure sensor chip, and uses the film resistance on the substrate to carry out zero point correction, zero point temperature compensation and sensitivity compensation. The high-performance and stable silicon chip package makes it high static pressure resistance, anti-interference, stable and reliable.
