BLS Level Sensor

The BLS Trimod'Besta Level Sensor is universally suitable for level detection and a real alternative to the tuning fork. It works in liquids of all kind, foams, bulk goods, granulates, even in liquids that are sticky, pasty and regardless of their viscosity.

On-site calibration is not necessary and the highly accurate sensor can be installed in any position. It has a very attractive, compact design and is completely maintenance free. Powered via an M12 connector it communicates its output status through a highly visible blue LED.


  • One sensor detects different media (liquids, bulk goods, foams: sticky, pasty or high or low viscosity)
  • Maximum temperature stability and repeat accuracy
  • Resistant to shocks and vibrations
  • Response time < 100 ms
  • Fully integrated electronics
  • Maintenance free
  • Small and good looking design
  • LED switching point indicator
  • Factory setting for DK (Ɛ) > 2.5

One sensor for many applications in different industries:

  • Pharmaceutical
  • Laboratory
  • Food & beverage
  • Watermanagement
  • Railway and vehicle construction
  • Machinery and apparatus engineering
  • Plant construction
  • Chemical and petrochemical industry
  • Shipbuilding
