摘要
A multi-position proximity switch having a plurality of binary outputs, each output indicating whether the distance between an object and a field transducer exceeds a corresponding one of a plurality of predefined distances. The sensitivity of a proximity detector having a single binary output is stepped through a plurality of adjustable levels by a digital counter having decoded outputs and the binary output of the proximity switch is sampled after the decoded counter outputs change state so that a plurality of binary outputs, each associated with a detector sensitivity level and a corresponding distance, are provided. The failure of the greatest distance to be detected or the detection of the smallest distance activates an alarm indicating that the object is outside a permissible range of distances.
