Temperature coefficient of sensitivity
Strain gage-based sensors show only a minute change in sensitivity resulting from temperature variation. This is due to the fact that the spring element materials' module of elasticity decreases with increasing temperature - equal force results in higher strain and thus a bigger output signal. The strain gages' gage factor (the sensitivity), too, is dependent on temperature.
With many force transducers the sensitivity's resulting dependence on temperature is compensated for and is thus very small. With both creep and error computation, it is essential that the specified value is always related to the current measured value.
