Abstract
A linear inductive transducer includes a non-magnetic former which has a bore in which is slidable a core formed from magnetic material. The core in use is moved axially within the former by the component whose axial position it is required to sense. The former has three circumferential grooves in which are located coils connected together to form the transducer winding the inductance of which varies with the axial position of the core. The widths of the coils and the number of turns in each coil varies so as to produce a substantially linear variation of inductance as the core is moved. A temperature responsive resistor is mounted in close proximity to the winding and is connected in a resistance network which includes the winding. The inductance of the winding is checked by applying a step voltage to the resistance network and monitoring the change of current in a part of the network.
