An inexpensive reflective displacement sensor with optical fibre links has two light output levels which switch when the measurand reaches a preset value. An autoreferencing unit monitors the light from the sensor at one level and continuously updates the system gain to compensate for intensity changes. Prototypes have been built; the paper presents results of repeatability trials.
