20mA Differential Pressure Sensor

20mA Differential Pressure Sensor

Product Description

4-20mA/0-5V/0-10V /RS485 low cost differential pressure sensor is a high reliability, stability, and accuracy DP transmitters. It is widely used in the field of liquid, gas pressure test, water, oil, and mildly corrosive liquids measurement.

The product material is 316L stainless steel, imported high accuracy silicon pressure sensor, dedicated amplifier and V / I conversion circuit transmitter, the specific anti-high voltage, high current, high magnetic field, polar lead and other characteristics.

4-20mA/0-5V/0-10V /RS485 low cost differential pressure sensor are piezoresistive differential pressure sensor as sensing element. Silicon oil is filled in between die and two diaphragms, when measured differential pressure is added on two diaphragms the pressure could be transferred onto die through silicon 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 petroleum, chemi-industry, power station and hydrology, etc. Designed according to user programmable pattern needs to change according to the situation in the field use the amount of zero and span range.
