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:
- 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
