Mineral raw materials

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.

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.

These products are available for uses in the field of mineral raw materials.

Thousands of sensors are reliably in use worldwide by this sensor in a wide variety of materials and industries.

The smallest of the sensors was specially developed for confined spaces and impresses with its compact design. We offer suitable weld-on fittings for use in pipelines.

Our CAN-capable sensor sends the signals directly to the customer's control and is processed on site.

The plug-in sensor is specially designed for on and off-road applications, vehicles in construction and agricultural areas as well as in engine applications.

Determination of the water content in liquids (emulsions/oils) and bulk solids in explosion-protected areas is possible with our WMS product family.

The modular design allows networking of up to 16 sensors on one evaluation unit. Extensive signal processing options for transfer to a higher-level control and the exact and fast calibration of the measured sections are just some of the many advantages.
