Abstract
An a.c.-fed temperature measuring bridge in the form of a balanced Wheatse bridge containing a temperature sensor R(.theta.) which, depending upon the measured temperature .theta., generates an output voltage which is balanced by a variable voltage y provided by ohmic ratio arms in such a way that if the sensor R(.theta.) has a non-linear characteristic, there will still be a linear relationship such that .theta. = const..sup.. y, the inventive feature being that the fixed ratio arms of the balanced Wheatstone bridge are formed by an inductive potential divider and that for correcting the non-linearity of the sensor the voltage across the variable ohmic ratio arms is a predetermined ratio (O.sub.3) of the voltage feeding the bridge.
