File Size : 116 KB Manufacturer:Sipex Description:The detection is done based on the ratio of two variable capacitors. These capacitors can be the parasitic capacitances of a small conductive ball placed on a cavity in the pcb. As the pcb is rotated in its lenghty direction, the ball is running forwards and backwards on the pcb. Copper tracks placed on the PCB at the edges of the hole will be used as the terminals of capacitors. We can define two capacitors made up of 2 copper tracks with a (conductive) ball in between. If the ball rolls just between 2 copper tracks, the distance between the copper tracks and the ball will decrease, thus increasing their capacitance. The circuitry on chip performs a measurement of the difference between these 2 caps. It controls the sense terminals (CA0, CA1, SUM), processes their data and drives 2 outputs: RD (to drive a relay) and LEDP (to drive an led). The information from the detection system
