Description

Technical Field

[0001] The utility model relates to the relevant field of bidirectional non-contact sensors, in particular to a bidirectional non-contact sensor. Background Art

[0002] A sensor is a device used to detect and respond to certain types of inputs from the physical environment. Specific inputs include light, heat, motion, moisture, and pressure. The output is a signal that is converted into the position of the sensor on a human-readable screen for further reading or processing. Sensors are divided into contact and non-contact types. Non-contact sensors usually rely on technologies based on electricity, magnetism, optics, sound waves or other principles to record position, speed, temperature, air quality and distance without contact. During the use of non-contact sensors, a protective structure will be installed outside the sensitive element of the sensor. The filter in the protective structure filters out impurities such as dust, oil, and water vapor in the air to prevent them from easily adhering to the sensitive elements of the sensor and affecting the accuracy of the sensor.

[0003] The existing device has the following shortcomings when in use: after long-term use, the filter is prone to dust accumulation and needs to be cleaned or disassembled and replaced to avoid affecting the accuracy of the sensitive element. It is inconvenient to disassemble the filter on the protective structure installed outside the sensor sensitive element. Utility Model Content
