Special precautions apply in areas where there is a risk of dust explosion.

Liebherr offers certified sensors for determining the moisture in bulk materials for the potentially explosive atmospheres Zone 21 and 22.

Bulk solids and materials such as coal, flour, wood, cocoa, coffee, sugar, starch and cellulose as well as magnesium and aluminium can be determined in-situ (real time) for the moisture value under particularly explosive conditions in conjunction with our proven FMS II evaluation and transfer unit. The sensors find their place in mixers, mills, dryers, conveyor belts, extraction points and the like.

Send the measured values directly and in-situ to your higher-level control system.

The self-sufficient measuring device for precise moisture determination in the running process guarantees the highest quality and safety in EX-protected production environments, the further processing and refinement of very many bulk materials.

The PC software enables fast and accurate calibration of the measuring sections.

Liebherr offers sensors for the following equipment protection categories:
