The accuracy of digital pressure gauges is affected by many factors, including design, manufacturing process, materials used, and later maintenance and calibration. Here are some details about the accuracy of digital pressure gauges:

Accuracy rating: The accuracy rating of the digital pressure gauge is usually marked on the dial and expressed as a percentage of the allowable error of the dial limit. For example, ±0.05% and ±0.1% are common accuracy levels 3 for precision digital pressure gauges.

The relationship between the measurement range and accuracy: The range of precision digital pressure gauges is usually 1.5 to 3 times the working pressure of the equipment, and the best choice is 2 times. If the range is too large, the absolute value of the allowable error will increase, affecting the reading accuracy; If the range is too small, during overvoltage operation, the pointer will exceed the maximum range and approach zero, which may lead to misjudgment.

The impact of the use environment: The use environment of the digital pressure gauge also affects its accuracy. For example, corrosive media may require the selection of elastic elements of different materials .

To sum up, the accuracy of digital pressure gauges is affected by a variety of factors, and users should consider these factors comprehensively when selecting and using to ensure accurate measurement results.
