Select the upper measurement limit of the pressure gauge 1. The upper limit value of the pressure gauge is designed based on the dimensions, stiffness and non-linear conditions of the spring tube. The upper measurement limits are 1 × 10 n, 1.6 × 10 n, 2.5 × 10 Five series of n, 4 × 10 n, and 6 × 10 n, n is a positive integer, a negative integer, or zero.
2. Digital pressure gauge pressure range: -100kPa ~ 2kPa ~ 260MPa.
3. The accuracy of the pressure gauge below 1/3 range is low, so it is not suitable for use. When selecting the upper measurement limit, in order to ensure the safe and reliable operation of the pressure gauge and maintain its service life, it should generally be greater than 1/3 of the maximum operating pressure.
4. When selecting the range of use, according to the universality of the load condition, it should be appropriate to use 1/3 to 2/3 of the full range, because this range of use is more accurate and can be used under both stable and fluctuating loads use. The range of use must not exceed 3/4 of the full scale of the dial.
