Level monitoring for chutes

Cost-effective photoelectric red light sensors are used to monitor the filling level of slides. While the PLC knows the exact volume of the individual parcels in a slide, it has no information on the actual space still available in the slide since the parcels occupy it in an irregular way. Several sensors installed along the edge of the slide provide the PLC with the pre-alarm and alarm signals required to manage and prioritize the subsequent loading activities. PinPoint LEDs generate an extremely bright, precise light spot.
