Conductive Sensors Level Probes Types CLH • • • • • Flexible conductive level probe 1 to 5 electrodes User defined electrode length Isolated or unisolated electrodes 1 1/2” pipe thread according to ISO 228/1-G11/2A Product Description Ordering Key A compact and flexible level probe for measuring the level of conductive liquids, i.e overfill, dry run protection or pump control. A total measurements system consist of a multiple probe- Type Head mounting Number of electrodes head, 1-5 electrodes and a control unit. The electrode length can be freely defined be means of electrode extention units with or without isolation.

Example Probe HiHi Y1 Hi Y3 Lo 12 Y5 Y2 Y4 REF Control Unit LoLo Functionality - example The diagram shows the level control system connected as max. and min control, i.e. registration of 2 levels + 2 alarm levels. The relays react to the low alternating current created when the electrodes is in contact with the liquid. The reference (Ref) must be connected to the container or if the container are made of a nonconductive material, to an additional electrode. In the diagram this electrode is shown by the dotted line. 24 14 Pump on/off A1 Alarm on/off A2 11 21 Power Supply to the desirable length. If using extended electrodes, place the enclosed isolation tube over the extension joint, Dimensions and heat it with a heat gun. Mount the electrodes in the probehead by means of the M4 screw inserts. Take care Connection cable 2, 3, 4 or 5 conductor PVC cable, normally screened. Cable length: max. 100 m. The resistance between the cores and the ground must be at last 200k. In normal cases it is recommended to use screened cable between probe and controller, e.g. where the cable is placed in parallel to the load cables (mains). The screen has to be connected to Y5 (reference).
