ABSTRACT:
A device for measuring the position of an element utilizing a linear variable differential transducer. The primary of the transducer is excited by using a single pulse, causing an induced pulse to be created at the secondary coil. The induced pulse is compensated for the effects of distortion. The induced pulse is sampled and compared with the input pulse to determine the amount of attenuation caused by the transducer, from which the position of an element attached to the transducer can be calculated.
