The SOLIBA is a tilt level switch for bulk solids located in non-hazardous areas. It has been designed to provide high level measurement in silos or any other type of storage containers. Its operation is very simple: Vertically suspended at the desired high level point, the SOLIBA will tilt as the grain reaches the unit. To secure your facilities at a minimum cost, the installation of a SOLIBA high level mechanical tilt level switch is strongly recommended, even if your facilities are already equipped with other types of equipment such as: rotating paddles, vibrating forks, radars, capacitive and ultrasonic sensors, etc.


  • Economical device, easy to install, easy to use
  • Robust construction, no risk of burial or clogging, even in low-density grains such as soy, sunflower, oats, and barley
  • Enhanced resistance to dust: IP 6X. The operation of the SOLIBA tilt level switch is not affected even when the device is completely covered with dust !
  • Energy saving: The SOLIBA tilt level switch only operates when the high level is reached, unlike other types of level measurement devices that operate permanently
  • Ecological tilt level switch (no mercury, no lead)


  • Grains and cereals: oats, sunflower, barley, soybean, rice, wheat, corn, sunflower, etc.
  • Animal food: for pets, for birds and poultry, for cattle, etc.
  • Powders: flou, sugar, cement, etc. 
  • Other bulk solids: granules, stones, minerals, sawdust, pellets, etc. 
  • High level measurement of silos, bins, hoppers, bulk storage zones, etc.
  • High level alarm (sound our light)

Remark: This device is not suitable for hazardous environments. Please select our SOLIBA EX ATEX certified tilt level swtiches.

Installation recommendations
  • The SOLIBA tilt level switch must be installed at the opposite side of the arrival of grain and at a certain distance from the silo walls. This to ensure an optimal tilting operation. 
  • For certain applications it is recommended to use an external ballast on the electrical cable. See external ballasts for SOLIBA tilt level switches.
  • A metal protection is available in option for any application involving physical shocks on the device or for high level detection of excessive-height bulk solids in all types of belt conveyors. See metal case for SOLIBA.
