User Guide
This tool will calculate the pressure error, accuracy factor or pressure range value for a pressure measurement device.
Use different pressure units to define the pressure measurement error 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 specified pressure measuring accuracy.
Formulas
The formulas used by this pressure measurement, accuracy and error calculator to determine each individual parameter are:
PE = P · Acc
Acc = PE / P
P = PE / Acc
Symbols
- PE = Error value in pressure units
- Acc = Accuracy as a proportion of a pressure value
- P = Pressure value
Pressure
This is the pressure value used to derive the percentage accuracy or the pressure error. The pressure range of a pressure measurement device is often used when calculating the pressure error since the accuracy is typically defined as a percentage of full scale (%FS).
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 pressure error value at a particular pressure reading.
Determining the pressure range required for a given pressure error deviation and percentage accuracy is useful for determining the maximum pressure range that would be possible, without exceeding a required maximum pressure deviation for a device with a defined accuracy.
Accuracy
This is the proportion of the pressure range or reading that defines the margin of error in measuring the true pressure value.
Error
This is the amount of pressure that a reading may deviate from the true pressure value.
