Moisture measurement

Liebherr has been developing measurement systems for industrial automation since 1985. Our sensors reliably determine the moisture in various materials. The benefit of Liebherr measurement systems is high precision thanks to 40 measurements per second, as well as the sensors' reproducibility. The systems can be integrated in various production facilities such as on conveyor belts, upstream and downstream of dryers, at transfer points, in hoppers but also in pipelines or tanks. Our systems measure, monitor and regulate the humidity or water content automatically and in real time the continuous measurement guarantees high precision.

Sensors are developed and manufactured at the Liebherr-Mischtechnik GmbH location in Bad Schussenried (Germany). Here, we produce and calibrate the sensors in an environment protected against ESD.

Reliability that promotes trust

We test each sensor over the entire working temperature range in a process that takes several hours.

When Liebherr started producing sensors, we used the measurement systems that we developed ourselves only in our own concrete mixing plants. Here, the sensors are used to determine the sand moisture in the process. For this task, we developed sensors that work reliably even under extreme outdoor conditions. Our experience in concrete technology pays off for our customers: Liebherr sensors measure precisely and have a long service life.

Examples of use for food and feed

  • Mounting on plot combine harvester
    Plot combine harvesters are used by plant breeders and experimental stations to harvest trial plots in a wide range of crops. The sensor can be used for all these products.

  • Use in grain drying facilities
    In order to make drying processes even more efficient and to determine the grain moisture exactly before storage, the use of Liebherr sensors and electronics is indispensable.

  • Use in seed
    Seeds are valuable. The residual moisture plays a major role in storing the seed appropriately without endangering its health and thus also its sprouting power.

  • Moisture determination in pistachios
    For good taste. Pistachios are also tested for residual moisture before they travel to consumers around the world. Mould formation and ageing can thus be ruled out. The Liebherr humidity sensors measure precisely and in real time.
