Upper measuring limit of pressure gauge
1. The upper limit value measured by the pressure gauge is based on the overall dimension of the spring tube
Designed under stiffness and nonlinear conditions, the upper limit of measurement is 1 × 10n、1.6 × 10n、2.5 × 10n、4 × 10n、6 × 10N five series, n is a positive integer, negative integer or zero.
2. Pressure range of digital pressure gauge: - 100KPA ~ 2KPa ~ 260mpa.
3. The accuracy of the part of the pressure gauge lower than 1 / 3 of the measuring range is low and should not be used. When selecting the upper limit of measurement, 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 service pressure.
4. When selecting the application range, according to the universality of load conditions, 1 / 3 ~ 2 / 3 of the full range should be selected, because this application range has high accuracy and can be used under both stable and fluctuating loads. The maximum range of use shall not exceed 3 / 4 of the full scale of the dial.
