The invention provides an adiabatic magnetostrictive sensor. In the working process of the adiabatic magnetostrictive sensor, a magnetostrictive sensor main body is connected with the inner wall of an adiabatic shell through a fixing mechanism. A threading hole is formed in the adiabatic shell, a connecting wire of the magnetostrictive sensor main body penetrates through the threading hole and is connected with the adiabatic shell in a sealed mode through a sealing mechanism, and the sealing mechanism enables the magnetostrictive sensor main body and the adiabatic shell to form a sealed space. The adiabatic shell is vacuumized through a vacuumizing air nozzle, so that a vacuum space is formed between the magnetostrictive sensor main body and the adiabatic shell, the magnetostrictive sensor main body works in the vacuum space, the vacuum space effectively isolates high-temperature or low-temperature transmission outside the adiabatic shell, the magnetostrictive sensor main body is prevented from working at a high temperature or a low temperature, the working stability of the magnetostrictive sensor main body is ensured, and the application range of the magnetostrictive sensor main body is widened.
Description
technical field [0001] The invention relates to the field of product protection, in particular to an adiabatic magnetostrictive sensor. Background technique [0002] The magnetostrictive sensor is a non-contact absolute value displacement detection device. Its basic principle is to measure the pulse mechanical wave propagation time in the magnetostrictive waveguide wire, combined with the propagation speed, to realize the position and magnetostrictive detection of the pulse mechanical wave. Displacement measurement between modules (energy pick-up mechanisms). Magnetostrictive sensors are widely used in walking machinery, material forming, metallurgical machinery and other fields, but the size of the output part of the transmitter of the magnetostrictive sensor on mechanical equipment with a small installation space often restricts the application of the magnetostrictive measurement principle. The structure of the output part of the magnetostrictive sensor transmitter is dir...
