Description

Technical field:

[0001] The invention relates to a large-range displacement sensor with waterproof function, which can be widely used in the fields of measurement test, on-line detection, product inspection, daily life and the like, especially in the field of production and processing, and belongs to the technical field of measuring instruments. Background technique:

[0002] Displacement sensors are the most widely used sensors, and large-range displacement sensors are used most in the industrial field, especially in the manufacturing field, such as gratings, magnetic gratings, capacitive gratings, inductive synchros, laser interferometry systems, etc. However, most of these traditional large-range displacement sensors have an obvious shortcoming and deficiency: when there are various liquids in the use environment, the measurement results of the sensors will have large deviations, and some sensors may not even work normally at all. This defect largely affects the use of th...
