Description

Technical Field

[0001] The utility model belongs to the technical field of pressure sensors, and in particular relates to a pressure sensor that is easy to adjust. Background Art

[0002] A pressure sensor is a device or apparatus that can sense pressure signals and convert them into usable output electrical signals according to certain rules. Pressure sensors are usually composed of pressure sensitive elements and signal processing units. According to different test pressure types, pressure sensors can be divided into gauge pressure sensors, differential pressure sensors and absolute pressure sensors.

[0003] A pressure sensor with an adjustable publication number of CN220912521U is retrieved, which specifically discloses: by rotating the adjusting screw 4 through the rotating disk 3, the main body 1 is driven to move up and down to achieve the adjustment effect. Since the external structure of the existing pressure sensor is relatively simple, it is difficult to adjust the pressure sensor body during installation. Although the above-mentioned device can adjust the position of the main body, since its adjustment components are exposed on the outside, dust will not only fall on the surface of the component and affect the subsequent adjustment during use, but also accidental contact will cause displacement and deviation of the pressure sensor body, thereby affecting the subsequent sensor detection.

The sensor body 1 slides up and down along the inside of the limiting slide groove 4 for adjustment. The protective sleeve 3 can be embedded in the sensor body 1 by setting, so as to protect the adjusting mechanism, and can avoid the adjusting mechanism and other components being exposed to the outside when the sensor body 1 is working or idle, thereby causing damage to the components, and the setting of the limiting slide groove 4 can limit the position of the sensor body 1 and the base body 2, and can avoid the two from being offset, which affects the stability of the subsequent adjustment of the sensor body 1;
