20mA Differential Pressure Sensor
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.
