Level sensors - System description

  • No moving parts means high reliability and long life
  • Measuring principle: guided wave radar, capacitive and hydrostatic
  • Outputs for continuous or point level measurement
  • Integrated LED display for local indication of the current level
  • Suitable for common industrial and process fluids

Level sensors
In industrial applications where fluids or bulk material are used, storage tanks or silos are used for processing or storing media. Sensors are used to detect levels. Even critical process conditions such as emptying a hydraulic tank or the unintentional overspill of a tank are monitored using level sensors.

Advantages of electronic sensors
Deposits or wear and tear often lead to failures, in particular if mechanical switches are in contact with the medium. But the electronic ifm sensors can do without any mechanical components. This makes the sensors especially robust and reliable. Another advantage of electronic sensors is the local indication of the level or the easy setting of the switching threshold simply by pressing a button.

Measuring principle
For continuous level measurement the level is detected continuously, converted into an electrical signal and indicated. Depending on the type the units have freely programmable switching outputs or an analogue output for further processing. Level sensors from ifm electronic operate to the physical principle of capacitive and hydrostatic level measurement as well as guided wave radar.
