Miniature waterproof pull rope type magnetic induction displacement sensor

Abstract

The invention provides a miniature waterproof pull rope type magnetic induction displacement sensor, which comprises an upper cover plate assembly, a circuit board, an electronic bin, a magnet assembly, a shell assembly, a pull box assembly and a clockwork spring assembly, and is characterized in that the circuit board is placed into the electronic bin from the upper end of the electronic bin; themagnet assembly is installed above the shell assembly, the pull box assembly is installed in the shell assembly, and the lower end of the electronic bin is connected with the upper portion of the shell assembly and covers the magnet assembly in the electronic bin. The spring assembly is installed on the lower portion of the pull box assembly, the pull box assembly is installed in the shell assembly in a sealed mode through the spring assembly, the upper end of the electronic bin is sealed through the upper cover plate assembly, and therefore the complete miniature waterproof pull rope type magnetic induction displacement sensor is formed. The device is simple in structure, stable and reliable in comprehensive performance, high in cost performance, convenient for large-scale production andcapable of completely replacing foreign brands.

Description

technical field [0001] The invention relates to a displacement sensor, in particular to a miniature waterproof pull-rope magnetic induction displacement sensor. Background technique [0002] The pull-wire displacement sensor is a kind of small size, simple installation, stable performance and high cost performance. It has been widely used in real-time monitoring of various mechanical linear motion data. By cooperating with the industrial control system, it can directly display various types of mechanical linear motion. Data monitoring and giving work instructions. In practical applications, its comprehensive performance index is directly related to the quality of the whole set of equipment control series. The existing waterproof pull rope displacement sensors on the market are basically dominated by foreign brands and are expensive, long delivery cycle, and poor after-sales service. to effective protection. The waterproof type pull rope displacement sensor on the market is...
