ETS-H Magnetostrictive displacement sensor during the measurement, the electronic components of the Electronic Chamber of the sensor generate a current pulse, which generates a magnetic field to move along the waveguide wire. The movable magnetic ring on the sensor rod also generates a magnetic field. When the magnetic field generated by the current intersects the magnetic field generated by the magnetic ring, the waveguide wire produces a magnetostrictive effect, producing a strain pulse. The pulse travels back along the waveguide wire at a fixed speed and is detected by the measuring element. By measuring the time between the current pulse and the strain pulse, the position (displacement) of the magnetic ring can be accurately determined.
