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.
