Temperature compensation in measuring technology

Several electrical sensors react more or less sensitively to temperature changes, which move the zero point and possibly change the sensitivity. They must therefore be balanced out by suitable measures, for example in the case of pressure measurements with a with the aid of compensation measuring strips, which are arranged perpendicular to the direction of the voltage and are switched to a full bridge using the "active" measuring strips (Figure T 9). A possible result is shown in (Figure T 10).
