Conductive level switch SLC series

for liquidsCEbrass

The level probes SLC series have the built-in management electronics and do not require auxiliary circuits to control alarms and / or actuators. The probes, being of a static type, without moving parts, allow an extremely precise control of the level of liquid The system is based on measurement of the conductivity of the liquid to be controlled and works with low potential and with alternating currents, in order to avoid the incrustation of the electrodes and / or perforation of the tank normally caused by the use of direct currents, which cause a galvanic action on materials. The contact of the electrode with the liquid under control determines the actuation of a relay inside the control unit. • AISI-316 Stainless steel electrodes • Built-in electronics • Relay output Control. Open the case, remove the leads from the terminals of the electrodes, terminals 1 and 3. Short circuit the terminals 1 and 3 of the terminal board, in these conditions, the relay must switch on and led has to light. Sensitivity adjustment. The unit is supplied with a factory setting of 20 µS. Install the control unit on the tank you have to control the level (The fitting acts as a ground electrode). Fill-up the tank to place the electrode in the liquid to be tested, turn the trimmer on the PCB to obtain the switching of the relay.
