HPT702 Air Differential Pressure Transmitter

Low range air differential pressure transmitter provides an accurate solution available from 0-50pa to 0-500Kpa DP. Incorporating the latest silicon sensor and electronics technologies, 4-20mA transmitters are fully temperature compensated for unrivalled stability at very low pressure.

Application :

● Leak detection device

● Boiler

● Brewing

● locomotives

● non-conductive non-corrosive gas

● HAVC Air differential pressure
