A method of increasing the voltage output of a Wheatstone bridge having one or two active arms is discussed. An increase of 80% is shown to be practicable without increasing the current in the gauge. This is achieved by using an asymmetrical bridge configuration instead of the more usual symmetrical arrangement. The effect of this configuration on output linearity is considered and a bridge‐balancing circuit is illustrated.
