Conductivity detector ELECTRA-SLA

floodingcontactliquid

This flooding detector allows an extremely precise control of the level of liquid. The system is based on measurement of the conductivity of the liquid to be detected and works with low potential and with alternating currents, in order to avoid the incrustation of the electrodes normally caused by the use of direct currents, which cause a galvanic action on materials. The contact of the electrodes with the liquid under control determines the actuation of a relay inside the control unit, with which you can drive alarms or drain pumps. ● Wall mounting. CONTROL AND ADJUSTMENT Control: Open the case, remove the leads from the terminals of the electrodes (terminals 1 and 3). Short circuit 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. Submerge the electrodes in the liquid to be tested, turn the trimmer on the PCB to obtain the switching of the relay.
