Description:

PT230BN Hvac Pressure Transducer is assembled with OEM silicon piezoresistive differential pressure core. The two pressure interfaces are pagoda cock structures (users can choose the pressure interface size), which can be directly installed on the measuring pipeline or connected through the pressure pipe. There are voltage, current, 485 signal outputs to choose from, which are easy to install and use, and are widely used in pressure process control fields in the power and coal industries such as boiler air supply and underground ventilation.

Application:

1- Oil water differential pressure measurement, pressure detection inside pipes and vessels

2- HVAC Equipment, can be used for heating, refrigeration, and other air conditioning equipment

3- Gas alarm, gas leakage alarm device applied in lab

4- Integrated system, applied to detecting gas-integrated systems in various industries.
