INTER SSR-W17 | Liquid Level Controller Relay

SSR type liquid level control relays are designed for the level control of
conductive liquids. Charging/discharging of the liquid automatically and
systematically from one container or a well to another provided with a very precise level controlling function is one of its most significant
characteristic.

USAGE

Operation With Three Electrodes: The relay is switched on when the electrodes are in conductive liquid. The relay keeps switching on even if the liquid level drops under the electrode (Upper Electrode). When the liquid level falls below the electrode (Lower Electrode), the relay switches off and motor stops. The relay is inactive until the liquid level reaches at the electrode (Lower Electrode). The relay switches on when the liquid level reaches at the electrode (Upper Electrode) and motor starts running.

Operation With Two Electrodes: The bottom electrode is connected to earth and surface of tank whereas other two electrodes (Upper and Lower Electrode) remain in the conductive liquid. Operation function is same as of 3 electrodes. This operation is used for earthing systems.

Operation With Single Electrode: The relay switches on when the liquid level reaches at the electrode. The relay switches off when the liquid level drops below the electrode.

Earth connection must be ensured for the operations with one electrode and two.
