Temperature sensing
Patent

OSTI ID:5719312
A temperature differential measuring circuit includes first and second temperature sensitive transducers disposed in corresponding first and second legs of a bridge circuit. Disposed in third and fourth legs of the bridge circuits are fixed resistors. An operational amplifier has its input terminals connected to the output terminals of the bridge circuit with its output terminal connected to one of the fixed resistors so that that fixed resistor is in feedback relation between the input and output of the amplifier. The transfer function of this bridge circuit is less temperature dependent than the transfer functions of conventional voltage bridge circuits.
