The level control relay RM35LM33MW controls 1 or 2 levels, with a fill or empty function and a low/standard/high sensitivity. The RM35LM33MW does perform detection by resistive probes. It features a sealable cover to help protect the settings and a control status indicator LED. Most common applications are to monitor the levels of conductive liquid or non-conductive material; to control the actuation of pumps or valves to regulate levels; to help protect submersible pumps against dry running, or to help protect tanks from “overflow”. These level control relays can also be used to control dosing of liquids in mixing processes and help protect heating elements in the event of non-immersion. The RM35LM33MW can be used in spring water, town water, industrial water, and sea water; metallic salt, acid, or base solutions; liquid fertilizers and non-concentrated alcohol (
