Float switches

One or more levels in a container can be monitored with a float switch. The contacts operate a pump directly or are evaluated by a control system.

Float switches are the cost-effective and maintenance-free alternative to complex and expensive electronic sensors.

Advantages of a float switch:

  • reliable
  • cost-effective
  • easy to install
  • maintenance and wear-free
  • potential-free; contact voltage up to 230 V
  • available with multiple switch points
  • can be combined with temperature switches and PT100
