Pressure gauges are commonly used mechanical equipment in industrial control and measurement processes. Pressure gauges can be divided into mechanical pressure gauges and electronic pressure gauges. Among them, mechanical pressure gauges are widely used because of their good elastic components and high mechanical strength. It is widely used in industrial production.
The working principle of mechanical pressure meters is to indicate the pressure value through the elastic deformation of the internal elastic sensitive elements under pressure. Mechanical pressure meters generally use spring tubes, diaphragms, bellows and bellows as elastic elements. These elastic elements are After the deformation occurs, the deformation will be amplified by the gear transmission mechanism, thereby displaying the corresponding pressure value.
The pressure measured by a pressure meter is generally a relative pressure, and it is also measured with atmospheric pressure as a relative point. The result displayed by the pressure meter is also the pressure of the measured object under atmospheric pressure. In the measuring range of the pressure meter, the pointer indicates the pressure value, and the dial corresponding to the pointer is generally 270 degrees.
