General information about planar sensor P78

The Liebherr P78 sensor in conjunction with the Liebherr FMS moisture measurement system has become indispensable for many industrial processes. Moisture measurement was invented in 1985 at the Bad Schussenried plant. Liebherr sensor measurement is based on the physical principle of capacitance determination in a high-frequency stray field. In addition to their high precision and robustness, the measuring devices from Bad Schussenried are characterized by their reproducibility.

General information about pipe sensor RMH12

The Liebherr in situ water content determination Litronic-FMS III-RMH12 is used to detect the water content (concentration determination) even in very low ppm ranges in emulsions such as diesel fuel, transmission, hydraulic, engine, rolling bearing, transformer and turbine oils as well as in battery systems. The sensors were developed in cooperation with the standardization committee according to ISO/TS 16332 for the water separation capacity of diesel fuel filters. They are installed in test and inspection benches and replace the previous manual sampling and other offline measurement systems. The Liebherr sensor measurement is based on the physical principle of capacitance determination in a high-frequency stray field.

General information about Litronic-FMS II evaluation and transfer module

A self-sufficient system with almost unlimited possibilities. The moisture measuring device of the type Litronic FMS II has already been used for decades in a wide variety of industries, where it measures the moisture content of a wide variety of materials in real time. At the beginning of each measurement section, calibration must be performed per product using reference methods. The Litronic-FMS II software enables convenient and fast parameterization. The evaluation unit receives the raw values measured by the Liebherr sensors and immediately converts them into percent moisture. Thanks to the various interfaces, transfer to a higher-level control system is possible.

General information about Litronic-FMS IV evaluation and transfer module PROFINET

A stand-alone moisture measurement device with high connectivity and many interesting possibilities. With ProfiNet technology on board, extensive signal processing and WEB based access, we are ready for Industry 4.0. Without Ethernet support, these tasks cannot be mastered. At the beginning of each measuring section, calibration must be performed per product using reference methods. The Litronic-FMS IV software enables convenient and fast parameterization. The evaluation unit receives the raw values measured by the Liebherr sensors and immediately converts them into the measured value, e.g. percentage moisture. Up to 16 sensors can be managed WEB -based with one unit. A curve manager and a material and sample management help the user to create the product specific calibration. Once the system has been calibrated, further measuring points can be set up or devices renewed on this basis at any time without great effort. The system thus always remains reliable, regardless of its previous runtime and age.
