Food and feed
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 salt works
Sensors and sliding shoe carriages in acid and salt-resistant design
in use in abrasive materials such as salts.
Use in lactose/cellulose
Product measurement in the drying oven on trays with a defined filling height with application ring is one of the ways to determine moisture in lactose or cellulose.
Use in artificial casings
The FMS II moisture measurement system enables efficient editing directly during operation.
Use in yeast
Determining the moisture directly in the yeast strand after the extruder enables direct intervention in the production process.
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.
Use in sugar beet pulp
Moisture measurement sensors used in the processing of sugar beet to pulp ensure that the moisture values are correctly maintained at all production levels.
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.
These products are available for use in the food and feed industry.
Litronic FMS P78
Thousands of sensors are reliably in use worldwide by this sensor in a wide variety of materials and industries.
Litronic FMS P30-S
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.Find out more
Litronic FMS P80-CAN
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.Find out more
Determination of the water content in liquids (emulsions/oils) and bulk solids in explosion-protected areas is possible with our WMS product family.
Litronic FMS II Evaluation and transfer module
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.Find out more
Litronic FMS IV Evaluation and transfer module
To meet the requirements of our customers, the new generation of the evaluation unit is based on ProfiNet data transmission. With the Ethernet standard, you and we react more flexibly and quickly to new and special requirements in process automation.
