Classification of measurement errors

A acceptable sensor obeys the afterward

rules

:

Is acute to the abstinent acreage onlyIs aloof to any added acreage acceptable to be encountered in its application

Does not access the

measured

property

Ideal sensors are advised to be beeline or beeline to some simple algebraic action of the measurement, about logarithmic. The achievement arresting of such a sensor is linearly proportional to the amount or simple action of the abstinent property. The acuteness is again authentic as the arrangement amid achievement arresting and abstinent property. For example, if a sensor measures temperature and has a voltage output, the acuteness is a connected with the assemblage V/K; this sensor is beeline because the arrangement is connected at all credibility of measurement.
