Principle

A pressure sensor is made out a piezoresister Wheatstone bridge. The pressure is applied to the diaphragm and passes through the silicon oil onto the Wheatstone bridge. When the pressure acts directly on the front face of diaphragm, the Wheatstone bridge will create a different voltage. This voltage difference can then be amplified to obtain a current signal of 4-20mA. measures the vertical depth of column of liquid and converts this depth into the standard amplified analog signals. These level transmitters feature a full-welded structure . The cable used in these transmitters is anti-oil. Water-proof and electromagnetic effect shielded PVC cable with vent hose for atmospheric pressure in. Easy for installing and using. With long service life.

Application scope: Measure and control of petroleum. Chemi-industry, power station, city water supply, drainage and hydrology etc.
