Level sensors

Pressure-resistant and reliable ultrasonic sensor for non-contact level measurement

Your Benefits

  • Non-contact and therefore wear-free measurement even in pressurized containers
  • Universal application – even in difficult media such as acids or bases
  • Quick and easy parameterization
  • Switching output and analog output in a single device
  • Adjustable ultrasonic cone for stable measurements even in tight installation spaces
  • Reliable blanking of stirrers possible
  • Measures accurately and reliably even in mediums with density fluctuations


Pressure-resistant and reliable ultrasonic sensor for non-contact level measurement

The UP56 ultrasonic level sensor is the ideal solution for demanding applications. The PTFE-protected transducer is pressure resistant up to 6 bar and also very resistant to difficult media. Stainless steel, PVDF and PFTE are also available as housing materials. This means the UP56 is suitable for non-contact measurement of aggressive, viscose, inhomogeneous or abrasive liquids and bulk materials. Thanks to the combination of two switching signals in one device, idling and overfill can be monitored at the same time. With an analog output and switching signal, continuous measurement with a separate overfill signal is also possible. The sensor is easy to parameterize using the integrated display, IO-Link or a Connect+ adapter.
