HPT708 Smart High Static Pressure Oxygen Services Differential Pressure Transmitters

1. Profiles:

HPT708 DP transmitter is a high reliability, stability, and accuracy DP transmitters. It is widely used in the field of liquid, gas pressure and level test, water, oil, and mildly corrosive liquids measurement.
       HPT708 DP Transmitters are piezoresistive differential pressure sensor as sensing element.
Halocarbon oil is filled in between die and two diaphragms, when measured differential pressure is added on two diaphragms the pressure could be transferred into die through halocarbon oil. Sensor die connects with amplifier circuit through wires, using semi-conductor’s piezoresistive effect, transforming differential pressure signal into electric signal. The whole product is used for differential pressure measurement of Oxygen services, liquid nitrogen, liquid CO2 and hydrology, etc.

   HPT708 not only apply in the field of liquid level measurement, but also which is used to measurement the gas or liquid differential pressure value. Also filled oil is optional according application environment.
