Description

ABSTRACT:
A multiple parameter sensor is disclosed having a preferred application in a turbine used in an auxiliary power unit. The multiple parameter sensor includes a first part (12) for rotation with a rotating member (14) having a speed of rotation to be measured; a second part (20) mounted in a fixed position adjacent the first part to respond to the speed of rotation of the first part to produce a first periodic signal (22), the second part in response to the first periodic signal producing a second signal representing the speed of rotation of the rotating member and comprising electrical winding (26) in which the first periodic signal is magnetically induced by rotation of the first part with the rotating member; and wherein the second part produces at least one additional signal with each additional signal representing one additional parameter of operation of the device associated with the rotating member.
