The magnetostrictive level transmitters is designed according to the magnetostrictive principle, which is a highly accurate, respond fast, good reliability, long life, smart structure level measuring instrument.

Magnetostrictive level transmitter adopts two-wire system 4-20mA with HART for level measuring, which is widely used in the applications of petroleum, chemical, food , metallurgy and so on .


The sensor of the magnetostriction liquid level meter is designed based on magnetostriction consists of sensitive waveguide wire,waveguide tube,moveable magnet and the electronic parts that emit electric pulse signal and receive the returned signal. When the electric pulse generated by pulse micro wave generator in electric probe transmit along the waveguide wire in the steel tube,electric pulse generated a toroidal magnetic field vertical to waveguide wire that transmit at the speed of light through waveguide wire.when the pulse toroidal magnetic field meets the inspection magnetic field,the two magnetic fields vectors overlays to create spiral magnetic field,generate instant twisting force and mechanical twisting force wave in the waveguide wire.the twisting force wave return to electric probe at the speed of light,make the two ends of coil create pulse induction. To measure the time difference between the pulse induction generated by the return of electric pulse and twisting force wave can precisely calculate the measured liquid same time,put the temperature sensor into the tube to measure the medium temperature.
