Description

Technical Field

[0001] The utility model relates to the field of displacement sensors, in particular to a displacement sensor. Background Art

[0002] Displacement sensor, also known as linear sensor, is a linear device belonging to metal sensing. The function of displacement sensor is to convert various measured physical quantities into electrical quantities. Displacement is a quantity related to the movement of the position of an object during motion. Small displacement is usually detected by strain, inductance, differential transformer, eddy current, Hall sensor, and large displacement is often measured by induction synchronizer, grating, capacitive grating, magnetic grating and other sensing technologies.

[0003] Displacement sensors are important devices for detecting changes in the position of objects, and displacement sensors are usually installed and fixed using mounting plates and screws. However, this installation method makes it difficult to fine-tune the position of the displacement sensor after installation. When adjusting the detection position of the displacement sensor, the displacement sensor needs to be disassembled and debugged again, which reduces the installation speed of the displacement sensor. To this end, we propose a displacement sensor to solve the above problem. Utility Model Content
