<p>An a.c.-fed temperature measuring bridge in the form of a balanced Wheatstone bridge containing a temperature sensor R(x) which, depending upon. the measured temperature x.degree.C,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(x) has a non-linear characteristic, there will still be a linear relationship such that x = const.?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 of the voltage feeding the bridge.</p> |
