ABSTRACT:
An apparatus and method for determining the position of a movable element. An elongated housing is provided for positioning generally adjacent an edge of an area in which the position of the movable element is to be determined. The housing has a base portion which contains a pair of spaced-apart transducers that are mounted in the surface of the base portion and face the area. An upper body portion of the housing is disposed above the base portion and protrudes in cantilevered fashion toward the area, so that the transducers are recessed from the area beneath the protruding upper body portion of the housing. Circuitry is provided for determining the position of the movable element from the respective transit times of energy propagating in either direction between the movable element and the pair of transducers.
