ABSTRACT:
A resistance bridge is temperature-compensated to provide acceptable values of sensitivity error and zero input error, by using a temperature-responsive current source from which are derived voltages which modify the bridge supply voltage and the bridge output voltage respectively. The output voltage is also modified to provide an acceptable sensitivity error by means of resistors in a circuit between output connections of the bridge and an output connection of the arrangement as a whole.
