The value determined to represent a measured variable and output at the signal output element. It is expressed as a product of a numerical value and the unit for the measured variable.
Compared with the correct value for the measured variable — the input variable for the measuring device — the measured value is associated with errors caused, for example, by an unfavourable arrangement of the sensor or the characteristics of the measuring device. A distinction must be made therefore between uncorrected measured values and measured values corrected to make up for identified systematic errors.
