HPT703 Micro Differential Pressure Transmitter

HPT703 Micro Differential Pressure Transmitter provides an accurate solution for low pressure sensing with ranges available from 0-250pa to 0-25Kpa. With variable capacitance sensing technology and argon arc welded sensitive components,it's advanced circuit linearity and temperature compensation technology makes better transmitter performance.

Application :

● Environmental contamination control

● Pipe pressure monitoring

● Medical equipment and devices

● Oven pressure boost and ventilation control

● Purification project

● Underground ventilation

Advantages
01Using ultra-sensitive air pressure sensor, it can be used for 0-25 Pascal air pressure.
02Built-in digital temperature compensation function that can withstand high and low temperatures, and can withstand extreme differential pressure environments.
03IP68 waterproof can be used in rain and snow weather.
04UL94V-0 flame retardant function can be used for flammable and explosive gases.
