(the permanent magnetic field is usually installed in the moving plate which should be detected,because of magnetostrictive phenomenon, waveguide wire will produce mechanical strain pulse at the point of intersection, meanwhile the mechanical strain pulse
returns to the electronic warehouse side by sound speed through waveguide wire, the strain pulse is detected by
the detection circuit in the electronic warehouse.so from launching an active pulse to receiving a strain pulse,
this time is the sound speed to pass the time in the waveguide wire .(here the time of the active wave operation has been ignored, actually the impact is only 0.0001%), known sound speed(the fixed amount is 3000m/s)and the delivery time..this distance is determined.when the permanent magnet moves to a new location,we should re-determine the measurement.so the magnetostrictive displacement sensor boasts high-accuracy, high-response, low hysteresis, high-reliability, non-contact, long life, easy for installation etc, so the magnetostrictive displacement sensor is widely used.
