How to choose the range of the pressure gauge?

Bai selection of pressure gauge range
1. When measuring the stable pressure, the maximum working pressure should not exceed zhi2/3 of the range.

2. When measuring the 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. To ensure measurement accuracy, the minimum 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 maximum pressure, select a value slightly larger than the value from the pressure gauge range series to be the selected range.
