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