The CRAB is an electronic level switch designed to detect the presence of water on flat surfaces while remaining anchored to the bottom. It operates based on the electrical conductivity of the water and is ideal for applications involving clean, rain, industrial, or chemically treated water.
The Schuko plug supplied with the float switch allows you to connect a pump without a switch directly to an electrical outlet to control its start and stop.
This patented device offers a reliable and adjustable solution for water level control in a wide range of environments.
