CLE1K Carlo Gavazzi

CLE1K, Conductive Sensors Level Probes Models CLH, CLE1K, Compact and flexible level probe to measure the level of conductive liquids: overfilling, protection against vacuum operation or pump control. The complete measuring system consists of a multi-probe head, 1-5 electrodes and a control unit. The length of the electrodes can be freely defined by means of electrode prolongation units, with or without insulation., CLE1K, Function: The diagram shows a connected level control as maximum and minimum control: that is, 2-level record + 2 alarm levels. Relays react to the low alternating current created when the electrodes are in contact with the liquid. The reference (Ref) must be connected to the vessel or, if the vessel is composed of a non-conductive material, to an additional electrode. In the diagram this electrode is indicated by the dotted line. Electrodes Cut or prolong the electrodes until the desired length is obtained. If you use prolonged electrodes, place the insulating tube over the extension gasket and heat it with a heat gun. Install the electrodes on the probe head using the parts for the M4 screws. Be careful not to damage the insulating material of the insulated electrodes. Connection cable PVC cable of 2, 3, 4 or 5 conductors, usually shielded. Cable length: max. 100 m. The resistance between the conductive wire and ground must be at least 200 k. In normal cases it is recommended to use a shielded cable between the probe and the relay, e.g. where the cable is placed parallel to the power (network) cables. The driver's display must be connected to Y5 (reference).
