Abstract
This relates to a circuit for generating a voltage which is proportional to changes in the resistance of a remote resistive sensing element, due to, for example, changes in temperature, pressure (such as from a strain gauge), etc. The sensing element is coupled to the circuit by three lead wires each having lead wire resistance. Means including first and second operational amplifiers are provided for cancelling errors in the output voltage due to voltage drops in the lead wires.
