Level sensors

Level sensors measure and monitor levels of liquids, gases, powders and bulk materials. A wide variety of sensor types and measuring principles can be used for level measuring techniques. Even in critical process states, our devices monitor, e.g., unintentional overfilling or emptying of containers, hydraulic tanks, silos or storage tanks. Read more here

Level sensors

Liquids in storage tanks or bulk material in silos – level sensors from autosen reliably register filling levels and issue overflow warnings. They can also be used to monitor critical process states such as the evacuation of a hydraulic tank or to prevent overfilling of a container.

Advantages of level sensors

No more overfilling! autosen’s electronic level sensors have no mechanical components, making them particularly robust, wear-free and resistant to malfunction. Level sensors work according to the capacitative level measurement technique and also the guided wave radar technique, thereby guaranteeing a high degree of reliability. Also, there is no need for regular cleaning or maintenance. Other advantages of electronic level sensors can be seen in the local display of the level as well as the easy switching level setting by pressing a key.
 

The advantages of our level sensors at a glance:

  • Since there are no mechanical components, they are highly reliable
  • Capacitive measurement technique with guided wave radar
  • Variable process connection technology by means of adapters
  • Outputs for continuous or point level monitoring
  • LED display for local indication of the current level
  • Suitable for common industrial and process liquids
  • No regular cleaning or maintenance needed
  • The switching level can be set easily by pressing a key

Application examples for level sensors

autosen’s electronic level sensors register the filling level of liquids or bulk material in hoppers, silos or storage tanks. They can also be used to monitor critical process states such as the evacuation of a hydraulic tank or to prevent overfilling of a container. Further uses for level sensors (for instance):
  • Level monitoring for oils in machine and plant engineering
  • Measuring levels or liquid cleaning agents and coolants
  • Prevention of unintentional overfilling /emptying of open and closed containers, hydraulic tanks, silos and storage tanks
