Abstract
A transducer for providing signals representative of the axial setting of an angularly movable component comprises a member having a first series of zones thereon, said zones having the same circumferential width and axial length and a sensing device having a sensing surface presented to the zones. As the area of the zones in turn presented to the surface of the device varies a fluctuating electrical signal is obtained which varies with the relative axial setting of the member and device. Calibration zones can be located between the zones respectively.
