Temperature Compensation

Temperature compensation refers to a measure for counteracting or correcting an undesired temperature influence. It is a correction applied to a measurement instrument to reduce errors attributed to temperature changes in a process media which is being measured or in the surrounding environment that the instrument is being used.

Ideally, temperature compensation will eliminate all effects of a change in temperature on the measured value delivered by a sensor.

This is an important issue in precision component manufacturing; as tolerances become tighter, the effect of temperature on component dimensions, and the need to allow for it, becomes more significant.
