Abstract
A displacement transducer includes a non-magnetic non-conductive former mounting helical bifilar windings. Slidable within the former is a conductive non-magnetic member the position of which is varied for the purpose of measuring displacement. The windings in use form the frequency determining component of an oscillator the frequency of which is a measure of the setting of the member.
