Since 1985 Liebherr develops, produces and distributes efficient moisture measurement systems for the industrial automation around the world.
At the beginning the moisture measurement sensors were used only for own LIEBHERR concrete mixing plants to determine the sand moisture in the process. This has fundamentally changed the last years and the sensors are used in different industrial sectors nowadays, from automotive supplier- to building material-, paper-, food industry to the agriculture sector further on for chemical and petrochemical applications.
Systems are installed for example in following materials:
Moisture: Building materials, quartz sand, cullet, minerals, plastic granules, paper, carton, pet food, wooden chips,
corn and maize, sugar beet, seed, fertilizer, biomass,… up to marzipan,
Water content: Diesel, crude oil, ethanol, paint…
At the Liebherr factory in Bad Schussenried the sensors are produced and calibrated in an ESD-protected production line. Sensor development at Liebherr includes the total R&D value chain from the physical idea to the final solution, from the first concept to the
finished product. The experience from the field of construction machines under extreme conditions guarantees a very high reliability and a long life time of the sensors.
The moisture measurement system FMS II is used, for example, in the agriculture sector in maize and grain drying pants. During drying process, the exact determination of corn/ maize moisture is most important for the storage of the goods. The sensors are installed in the dryer inlet and outlet and monitor directly in the material flow the moisture content of the material. With this the two maize or corn moisture levels are compared and then the drying process will be controlled accordingly.
