Float switches are a reliable and inexpensive solution for the direct control of pumps and regulate liquid levels in tanks, basins and the like.
The types EHZ-5.1, 6.1, 6.2, 6.3 and B are available with different cable types and, depending on the choice, resistant to water, wastewater, oils, fats and most acids and bases.
The float switches FS-E, FS-C, FS-E2 and FS-C2 are supplied with a high-quality neoprene cable, which is specified for use in water and wastewater and is also resistant to most acids and bases.
Our float switches are always made to order and the cable length can be defined by the customer.
