Moisture measurement and water content determination
Liebherr has been developing measurement systems for industrial automation since 1985. Our sensors reliably determine the moisture and water content in various materials and liquids. 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.
Application examples for chemical products
Use in fertiliser
The residual moisture plays a major role in storing the fertiliser appropriately without endangering its quality and thus also its effect.
Use in plastic granulates
Measurement of low moisture levels directly before and after the drying process with the Liebherr moisture measuring installation and specially developed sensors.
Use on paints and lacquers
In mostly explosion-protected environments, we also use our systems to determine the moisture or water content in paints and lacquers.
Use in washing powder, detergent and soap
The Liebherr moisture measuring installation guarantees exact compliance with the target moisture content when processing chemical ingredients.
Use in glue
The water content in glue is critical for its quality.
These products are available for use in the field of chemical products.
