The invention provides a magnetic transmission displacement sensor which comprises a support, a magnetic wheel, a rotating shaft, slide blocks and angular displacement sensors. U-shaped slide grooves are formed in the two ends of the support respectively. The slide blocks are arranged in the slide grooves. The angular displacement sensors are fixed to the slide blocks. The rotating shaft and the magnetic wheel are connected into a whole and penetrate through the two slide blocks to be connected with the shaft input ends of the angular displacement sensors. In the use process, the magnetic wheel is attached to the surface of a measured moving body and rolls on the moving body. Through the magnetic force of a magnet, the magnetic wheel is tightly attached to a piston rod, the magnetic wheel can be reliably driven to rotate without sliding when the piston rod moves, and therefore the aim of measuring displacement is achieved after the angular displacement sensors connected with the magnetic wheel send out signals.
Description
technical field [0001] The invention relates to a magnetic force transmission displacement sensor. Background technique [0002] Displacement measurement of moving parts such as hydraulic cylinders or pneumatic cylinders is the key to their control. The current measurement methods are mainly divided into two types: external displacement sensors and built-in displacement sensors. The external displacement sensor is generally connected to the linear displacement sensor through a pull rod. When the piston rod moves, it drives the linear displacement sensor to send out a displacement signal; some use a pull wire to connect the angular displacement sensor. When the component moves, the pull wire affects the angular displacement connected to it. The sensor rotates to send out a displacement signal. The built-in displacement sensor generally makes the moving part (mostly a piston rod) hollow, and installs a displacement sensor (usually a magnetostrictive displacement sensor) insid...
