MTF1/MTF2 Slider Magnetostrictive Displacement Sensor Overview:


The change in the direction of magnetization in the ferromagnetic material will cause the change in the lattice spacing of the medium, so that the length and volume of the ferromagnetic material will change, that is, the magnetostriction phenomenon, also known as the Wiederman effect, and its inverse effect is called 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 convert the accurate position. The two magnetic fields, one from the permanent magnet in the magnetic ring, and the other from the excitation pulse generated by the electronic components in the sensor's electronic compartment. The excitation pulse travels at the speed of sound along a waveguide filament made of magnetostrictive material inside the sensor. When intersecting with the permanent magnet field in the magnetic ring, the mechanical vibration generated by the waveguide wire forms a strain pulse due to magnetostriction. The strain pulse is quickly detected by a sensing circuit in the electronic chamber. From the moment when the excitation pulse is generated to the total time when the strain pulse is detected by a fixed sound speed, we can accurately calculate the position change of the magnet. This process is continuous, so whenever the position of the magnetic ring changes, the new position is quickly measured. Since the output signal is a true position value, rather than a proportional or reamplified signal, there is no signal drift or variation, let alone the need to periodically re-label as with other sensors.

 

Magnetostrictive sensors are non-contact and never wear out. It has the advantages of high resolution, high precision, high stability, high reliability, fast response time and long working life. Sensors do not need to be re-calibrated or regularly maintained.
