The latest white paper from Beamex has focused on a fundamental consideration in any measurement or calibration – uncertainty.
The paper is designed for people who are not mathematicians or metrology experts, but rather those who are planning and making the practical measurements and calibrations in industrial applications.
The uncertainty of measurement can come from various sources, says Heikki Laurila, product marketing manager at Beamex Oy Ab; whether it be the reference measurement device itself, the environmental conditions, the operator making the calculations, etc.
Every measurement made has some ‘doubt’, adds Laurila, but it is important to know how much this ‘doubt’ is in order to decide if the measurement is good enough for the usage.
The paper also suggests that error is not the same as uncertainty. When a device about to be calibrated is compared against the reference standard, the error is the difference between these two readings.
However, says Laurila, the error does not have any meaning unless the uncertainty of the measurement is also known.
