Liebherr Litronic FMS P78-E Planar Moisture Sensor
Small, fine, excellent: The Liebherr P78-E sensor in conjunction with the Liebherr FMS moisture measuring installation has become indispensable for many industrial processes. The moisture measuring installation was invented in 1985 at the Bad Schussenried factory. Measurement by the Liebherr sensor system is based on the physical principle of capacitance determination in the high-frequency stray field. In addition to their high precision and robustness, the measuring devices from Bad Schussenried are characterised by their reproducibility.
Once the sensor has been calibrated, further measuring points can be set up or devices renewed on this basis at any time without great effort. The plant thus always remains reliable, regardless of its previous term and age.
- Indirect measuring method: Capacity determination in the high frequency stray field. This method uses the different dielectric constant (permittivity) of water and different materials (solids and liquids).
- Fully reproducible sensors: If the plant is subsequently extended with sensors or if sensors are replaced, no recalibration is necessary thanks to the built-in microprocessor.
- Waterproof and dustproof: The sensor is also suitable for the harshest environments thanks to its IP68 protection class.
- Very hard wearing protection: The sensor surface consists of a 2 mm thin zirconium oxide ceramic.
- Process control and regulation: Thanks to extensive interfaces, the moisture measurement can be integrated into process control systems and controls.
- Cost saving: Time-consuming and costly laboratory analyses are no longer necessary or can be reduced.
- Limit values: Maximum or minimum limits can be set using the software. Light or sound signals can be triggered if required.
- Mean value calculator: The sensor passes on already averaged values to the FMS evaluation and transfer module.
