How to choose and formulate the range of precision pressure gauge

Precision pressure gauges are common measuring instruments and are widely used in various production fields. The selection of precision pressure gauges should be based on the requirements of use, and on the premise of meeting the technological requirements, comprehensive consideration should be given to the principle of economy and practicality, so that the accuracy level, range, type and model should be selected reasonably. So, how to choose the range of the pressure gauge? Zhuhai Tianchuang Instrument Company summarized the following points for everyone:
1. When measuring stable pressure, the maximum working pressure should not exceed 2/3 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 this value from the pressure gauge range series to be the selected range.
