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

Advantages
01The best solution for differential pressure measurement of air, flammable and explosive gas or HAVC system.
02The automatic temperature compensation function is suitable for more severe working conditions.
03The explosion-proof aluminum alloy shell is more suitable for measuring the differential pressure of flammable and explosive gases.
04Differential pressure manufacturer.
