Precision pressure gauge refers to an instrument that uses elastic components as sensitive components to measure and indicate pressure higher than the ambient pressure. Its application is extremely common. It covers almost all industrial processes and scientific research fields. It can be seen everywhere in the fields of heating pipe network, oil and gas transmission, water and gas supply system, vehicle repair and maintenance factories and stores. Especially in the process of industrial process control and technical measurement, because the elastic sensitive element of the mechanical pressure gauge has the characteristics of high mechanical strength and convenient production, the mechanical pressure gauge is more and more widely used.
How to choose the range of precision pressure gauge:
1. When measuring stable pressure, the maximum working pressure should not exceed 2/3 of the range.
2. When measuring pulsating pressure, the maximum working pressure should not exceed 1/2 of the range
3. When measuring high pressure, the maximum working pressure should not exceed 3/5 of the range
4. In order to ensure measurement accuracy, the small working pressure should not be less than 1/3 of the range. According to the above principles, after calculating a value based on the measured pressure, select a value slightly larger than the value from the pressure gauge range series to be the selected range.
