User Guide

Use this tool to calculate the output error of a pressure sensor by entering the calibration reference pressure reading, pressure sensor range and measured output.  You can choose to calculate the error as a proportion of the pressure range, or in output or pressure units.

Pressure

This is the pressure which is measured by the pressure sensor, you can either enter a value to see what output to expect from a pressure sensor or you can enter the value verified by a calibration reference and compare it to the actual output to determine the calibration error.

Low Limit

This is lowest pressure which the sensor will measure, and is used to define the lower limit of the pressure range, that also corresponds to the lowest output value.

High Limit

This is highest pressure which the sensor will measure, and is used to define the upper limit of the pressure range, that also corresponds to the highest output value.

Output

This is what the pressure sensor sends out in the form of an analogue signal or digital reading.  The output will typically vary proportionally with the measurement range as a straight line, although there will be slight deviations due to the accuracy limitations of the pressure sensor.

% Error

This the proportion of the pressure sensor output range which represents the amount of deviation from a perfect measurement. It is used to define the specification limits of pressure sensors on manufacturers product data sheets and brochures, and also to calculate calibration errors. Accuracy is often expressed as a percentage of full scale for pressure sensors.

Pressure Error

This is the amount of pressure deviation from a perfectly accurate measurement, and represents the scope of uncertainty in the output of the pressure sensor, expressed in pressure units.

Output Error

This is the amount of output deviation from a perfectly accurate measurement, and represents the scope of uncertainty in the output of the pressure sensor.
