Operating range of the excitation voltage
The excitation voltage is the force transducer's supply voltage; in general a range is specified. It is essential not to exceed the maximum excitation voltage, since otherwise the permissible voltage at the strain gages will be exceeded. As a consequence, the electrical power will be too high and the strain gage will become too hot. This will result in a change in zero point (temperature effect on zero point) and a change in sensitivity (temperature effect on sensitivity).
