This tool will calculate the tolerance value, accuracy factor or pressure value for a pressure measurement device.
Use different pressure units to define the pressure measurement tolerance to avoid long decimals with too many leading zeros.
Define accuracy as a percentage value or a parts per million factor, plus a few other rarely used methods to express measurement accuracy.
Determine the largest pressure range that can be used to achieve a specific pressure measuring accuracy.
The formulas used by this pressure measurement, accuracy and tolerance calculator to determine each individual parameter are:
Tol = P · Acc
Acc = Tol / P
P = Tol / Acc
- Tol = Tolerance value in pressure units
- Acc = Accuracy as a proportion of a pressure value
- P = Pressure value
This is the pressure value used to derive the accuracy or tolerance. The pressure value used is often the pressure range of a pressure measurement device, since typically the accuracy is a fixed value across the whole range. For pressure calibration equipment the accuracy is sometimes defined as a percentage of reading, and in this case it would be a specific pressure reading that would be used to calculate the tolerance.
This is a proportion of the pressure range or reading that defines the margin of error in measuring the true pressure value.
This is the amount of pressure that a reading may deviate from the true pressure value.
