The TEC Magnetostrictive Displacement Sensor Auxiliary Cylinder is a new-generation straight-line displacement measurement solution independently developed by TEC. It integrates the principles of magnetostrictive effect with advanced electronic processing technology, enabling it to provide real-time, reliable, precise, and continuous straight-line displacement signals in harsh working environments. This auxiliary cylinder commonly serves as a supplementary component to the primary measurement system, enhancing measurement accuracy, stability, and reliability.

The working principle of the TEC Magnetostrictive Displacement Sensor Auxiliary Cylinder is based on the magnetostrictive effect and Wiedemann effect. During measurement, the excitation module in the electronic housing applies a query pulse to both ends of the sensitive detection element (waveguide wire), creating a circumferential Ampere-type ring magnetic field around the waveguide wire at the speed of light. When this ring magnetic field interacts with the bias permanent magnetic field of the moving magnetic ring (typically mounted on the auxiliary cylinder), which represents positional changes, a Wiedemann effect torsional stress wave is generated on the surface of the waveguide wire. The torsional wave propagates from the point of origin towards both ends of the waveguide wire at the speed of sound. The wave traveling towards the end is absorbed by a damping device, while the signal traveling towards the excitation end is received by a wave detector. By measuring the time difference between the query pulse and the received signal and multiplying it by the propagation speed of the torsional stress wave in the waveguide material (approximately 2800m/s), the precise position of the moving magnetic ring can be calculated, thereby achieving displacement measurement.
