ABSTRACT:
A signal conditioner for a linear variable differential transformer having a first amplifier which senses the differences in amplitude between secondary alternating current voltages in the two secondaries respectively, and a second amplifier which compares the phase of the difference signal from the first amplifier with the phase of one of the secondary alternating voltages. A conditioned signal A.sub.out is output by the signal conditioner according to the equation A.sub.out =K.sub.1 V.sub.s1 +K.sub.2 (V.sub.s1 -V.sub.s2) where K.sub.1 and K.sub.2 are constants, and V.sub.s1 and V.sub.s2 are instantaneous voltages across the respective secondaries.
