Humidity Sensors
Litronic FMS | Reliable Moisture Measuring System
Our comprehensive programme expansion in the product line of moisture measurement technology includes sensor systems for the determination of moisture, water content as well as layer thickness and weight per unit area. Liebherr, as our cooperation partner, has many years of experience in the field of capacitive measurement technology, which is used here. Through this capacitive measurement of moisture and water content, our Litronic FMS sensor system provides the important information to control and regulate our customers' process chains in real time (in situ). In this way, we enable our customers to achieve significant increases in efficiency through optimised use of resources.
