Abstract
A circuit and a process for converting the output signal from a half bridge transducer to that from an LVDT transducer to enable direct use of either signal in an electronic column. The circuit subtracts the transducer exciting signal from a half bridge transducer output signal according to a formula to provide the conversion. A movable jumper allows the circuit to alternatively operate as a unity gain follower to pass an LVDT transducer output signal unchanged.
