Level sensors

Tough, non-contact, pressure-resistant

Your Benefits

  • Non-contact and hence wear-free measurement in pressurized containers
  • Easy parameterization, saving time
  • Flexible measurement on many different sized containers with only one sensor saves storage costs
  • Switching output and analog output combined in a single device
  • Adjustable sonic beam for stable measurements even with limited installation space
  • Reliable blanking of stirrers possible


Tough, non-contact, pressure-resistant

The product family UP56 of ultrasonic level sensors is the ideal solution for demanding applications. The teflon-protected transducer handles overpressure up to 6 bar (87 psi) and is resistant against numerous difficult fluids. Wetted parts can be chosen either as stainless steel or PVDF, thus making the UP56 the perfect solution for measurement in aggressive, viscous, or abrasive liquids, or bulk solids. By combining two output signals in one device, new cost-effective solutions can be created for measurement and integration into the system. With two switching outputs, the UP56 can measure dry running and overflow in one device. Combining analog and a switching output enables continuous level measurement with a separate overflow signal. Parameters are easy to set via an integrated display, PC or the connect+ adapter.
