Problems solved by technology

[0003] The magnetostrictive displacement sensors currently available on the market can only separate the sensor from the digital display device. In some work sites, during operation or maintenance, it is inconvenient for workers to directly read the data and identify the working status of the sensor. Therefore, it is hoped to provide a The sensor has the function of on-site reading, which is convenient for workers to operate

Abstract

The invention relates to a displacement sensor used for field reading. The displacement sensor used for the field reading comprises a measuring main body, a magnet and a detecting rod; the magnetostriction principle is used for measuring the distance, and the displacement sensor is characterized in that a liquid crystal display screen is arranged on the measuring main body and used for displaying the measuring value. The displacement sensor can realize the field reading, and the working and detection of field workers are convenient, meanwhile the cost is reduced, and the application scope is enlarged.

Description

technical field [0001] The invention relates to the field of magnetostrictive displacement sensors, in particular to a displacement sensor for on-site reading. Background technique [0002] The magnetostrictive displacement sensor is a non-contact measuring instrument that uses the Wiedeman effect and the Villary effect of the magnetostrictive material to detect the absolute position of the movable magnet to measure the actual displacement value of the detected product. High resolution, high linearity, absolute position signal output and high protection level (IP69) and other significant advantages can meet the needs of most production sites. [0003] The magnetostrictive displacement sensors currently available on the market can only separate the sensor from the digital display device. In some workplaces, during operation or maintenance, it is inconvenient for workers to directly read the data and identify the working status of the sensor. Therefore, it is hoped to provide ...
