Description:
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 principle.it 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 hight.at same time,put the
temperature sensor into the tube to measure the medium temperature.
