(Optical Sensor)
All LEVELITE optic probes operate by sensing the difference between liquid and air (or other gas) using an infrared light source and detector. An optic LED produces infrared light that is directed down the probe. When dry, the light is reflected through the probe’s conical tip and is sensed by the photo-detector. When the probe tip is wet, the light at the photo-detector produces a change in the output. LEVELITE offers self-contained level switches as well as electro optic and fiber optic level systems. Electro optic probes are designed for general purpose areas and fiber optic probes for hazardous areas. These probes are used in conjunction with a universal controller, which can be used for level alarms or pump control. The universal controller has adjustable time delay and field selectable “fail-safe” settings.
