<p>A piston (14) position in a cylinder (12) of a hydraulic assembly (10) is measured using microwave pulses. The microwave pulses are launched along a conductor (22) coupled to the piston (14) or cylinder (12). A sliding member (34) is slidably coupled to the conductor (22) and moves with the piston (14) or cylinder (12) .Position is determined as a function of a reflection from the end (32) of the conductor (22) and the sliding member (34).</p> |
