Product Description

 

The structural part of the magnetostrictive liquid level sensor is composed of a stainless steel tube (a measuring rod), a magnetostrictive wire (waveguide wire), a movable float (with a permanent magnet inside), and the like. When the sensor is operating, the circuit portion will excite a pulsed current on the waveguide wire that will generate a pulsed electromagnetic field around the waveguide wire as it propagates along the waveguide wire. A float is arranged outside the sensor rod, and the float can move up and down along the rod as the liquid level changes.
