The level differential switch WPS 4000 is suitable for automatic level monitoring of conductive liquids in containers, wells, water tanks and the like. Monitoring takes place via electrodes. Among other things, the device protects units and systems from damage due to leaks, unnecessary fluid losses and from dehydration and flooding. It monitors and controls liquid levels wherever a certain fill level must be maintained. For installation in sub-distributions, switchboards, surface-mounted enclosures, etc.
The following functions can be implemented: refill, empty, refill with emergency stop, refill and empty, refill with manual emergency stop, refill with automatic and manual emergency stop.
