Description

Technical Field

[0001] This utility model relates to the field of pressure gauge movement technology, specifically a pressure gauge movement that is easy to assemble. Background Technology

[0002] A pressure gauge is an instrument that uses an elastic element as its sensing element to measure and indicate pressures higher than ambient pressure. It is extremely widely used, found in almost all industrial processes and scientific research fields. Especially in industrial process control and technical measurement, mechanical pressure gauges are increasingly widely used due to the high mechanical strength and ease of production of their elastic sensing elements. The working principle of a pressure gauge is based on the elastic deformation of the sensing element inside the gauge, such as a bellows, diaphragm, etc. The pressure deformation is then transmitted to the pointer by the internal mechanism, causing the pointer to rotate and display the pressure.

[0003] Existing pressure gauge movements are typically housed within a casing. The installation process involves first installing the movement and then the casing. Since the movement is cramped, installation is relatively inconvenient. Furthermore, the simple metal casing offers insufficient protection against impacts and leaks, making the movement susceptible to damage from impacts or water seepage, which can cause vibrations and lead to measurement errors. Therefore, we propose a pressure gauge movement that is easy to assemble to address these issues. Utility Model Content
