Abstract
A thrust sensor assembly suitable for use with an actuator of the type wherein motive power is applied to an actuator shaft and wherein the thrust sensor assembly comprises a first compression plate means and a second compression plate means, at least one of said compression plate means being on or adapted to engage directly or indirectly with a said shaft to move axially with the shaft and the second compression plate means being arranged to oppose the first compression plate means with resiliently compressible pad(s) sandwiched there between, a pressure transducer being mounted on one of the first or second compression plate means, whereby movement of the first compression plate means toward the second compression plate mans compresses the compressible pad(s) between the two compression plate means and against the pressure transducer and thereby inducing a signal from the pressure transducer that corresponds to the thrust of the actuator shaft.
