MTL3 Magnetic ring Magnetostrictive displacement sensor overview:
In ferromagnetic material, the change of magnetization direction will cause the change of dielectric lattice spacing, so that the length and volume of ferromagnetic material change, namely: magnetostriction phenomenon, also known as the Widman effect, and its inverse effect is known as the Villari effect.
The principle of magnetostrictive displacement sensor is to generate a strain pulse signal when two different magnetic fields intersect, and then calculate the time period required for this signal to be detected, so as to
calculate the exact position. One comes from a permanent magnet in the ring and the other from an excitation pulse generated by an electronic component in the sensor's electronics chamber. The excitation pulse runs at the speed of sound along a waveguide wire made of magnetostrictive material inside the sensor. When intersecting with the permanent magnetic field in the magnetic ring, the mechanical vibration generated by the waveguide wire forms a strain pulse due to the magnetostriction phenomenon. The strain pulse is quickly detected by a sensing circuit in the electronic chamber. Multiply the total time from the moment the excitation pulse is generated until the strain pulse is detected by a fixed speed of sound, and we can accurately calculate the position change of the magnet. The process is continuous, so every time the position of the ring changes, a new position is quickly measured. Since the output signal is the true position value, rather than a proportional or re-amplified signal, there is no signal drift or change of value, let alone the need to periodically resold as with other sensors.
