Dry running protection for submersible motor-driven pumps
- Pumps and compressors
- Monitoring of household wells so that they are not pumped dry, and to ensure that the pump does not run dry.
- Minimum fill level monitoring with suspended probes (SK1). This ensures that the pump is not run dry. A switch-on and return delay also prevent loads from brief operation.
- - Prevention of possible pump damage
- Motor protection
- Operating safety

Sewage pump peak loadcoverage
Two pumps are installed at a sewage pumping station that are to be run alternately for equal periods to ensure equal wear.
Fluid level monitoring
When the pools at a waste water treatment plant are filled to a constant level, this causes undefined states for the float switches (a “flutter state”).
Prevention of filling a tank with air/monitoring a tanker at a minimum level.
Monitoring of the operating state of the belt scraper. The belt scraper could get blocked. This can cause the drive chain to become damaged or break.
Sewage plant rake drive
The goal is to monitor a sewage plant rake for overload, and to switch it off when it is blocked by large pieces of wood.
Fountain fill level
The fill level must be monitored in fountains so that the water pump can be activated when the water level is too low.
