Question:

The greater the accuracy of a pressure gauge, the higher or lower the accuracy of the measurement, or the difference between the two

The greater the accuracy of a pressure gauge, the higher or lower the accuracy of the measurement, or the difference between the two

Answer:

The greater the accuracy of the pressure gauge, the lower the accuracy of the measurement!For example: the accuracy level of the pressure gauge is 1.6, which represents the maximum allowable error of the pressure gauge is + 1.6%. If 0~10MPa, the maximum allowable error is + 0.16MPaThe accuracy level of the pressure gauge is 2.5, which represents the maximum allowable error of the pressure gauge is + 2.5%. If 0~10MPa, the maximum allowable error is + 0.25MPaIt can be seen that the measurement accuracy of level 1.6 is higher than that of level 2.5.
The greater the accuracy of the pressure gauge, the lower the accuracy of the measurementThe degree of accuracy is the smallest unit of value that can be measured. The greater the value, the lower the accuracy.
2.5 represents the accuracy of the maximum range of 2.5%, 1.5, 1.5%, so the larger the number, the lower the relative accuracy, when it is necessary to pay attention to its maximum range is how much
