SRM901 magnetostrictive linear displacement liquid level transmitter

SRM901 magnetostrictive linear displacement (liquid level) transmitter is mainly composed of a measuring rod, an electronic bin and a non-contact magnetic ring (floating ball) sleeved on the measuring rod. A magnetostrictive wire (waveguide wire) is installed in the measuring rod. During operation, when an initial pulse is generated by the electronic circuit in the electronic warehouse and transmitted in the waveguide wire, the colleague generates a rotating magnetic field advancing in the direction of the waveguide wire. When this magnetic field meets the permanent magnetic field in the magnetic ring (floating ball), it generates a magnetostrictive effect, which causes the guide wire to generate a twist pulse, or a “return” pulse. This twist pulse is installed in the electronic warehouse The energy pickup mechanism senses and converts it into corresponding current pulses. The time difference between the start and return of the two pulses is calculated by the electronic circuit, and the measured position displacement can be accurately measured.
