Fossil raw materials/petrochemistry

Liebherr has been developing measurement systems for industrial automation since 1985. Our sensors reliably determine the moisture or 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. 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. The sensors determine the sand moisture in the running 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 applications in the field of fossil raw materials and petrochemistry.

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

The pipe sensor was specially developed for determining the smallest amounts of water (trace moisture) in liquids. The sensor in conjunction with the FMS III evaluation and transfer unit is used, for example, in test and trial systems for monitoring the water separation ability in diesel fuel filters.

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.

Under explosive conditions, our Litronic WMS enables reliable water content determination in various bulk solids, emulsions and liquids.
