Arrangement for monitoring liquid medium in channel system for e.g. fermentation plant, has magnetic systems arranged such that field is extended to interact with element, where element is connected with probe so to produce force on probe
Arrangement for monitoring liquid medium in channel system for e.g. fermentation plant, has magnetic systems arranged such that field is extended to interact with element, where element is connected with probe so to produce force on probe
The arrangement has magnetic systems (90, 110) for generating magnetic field. The magnetic systems are arranged on or in a channel system (1) such that the field partially extends into the channel system and liquid medium (2) in an operating mode of the magnetic systems, so that the field interacts with a magnetic element of a radio frequency identification (RFID) probe (50) when the probe is provided in sphere of influence of the systems. The element is firmly connected with the probe, so that force is produced on the probe in preset direction by generation of the field. The magnetic systems are formed as permanent magnets, and the RFID probe is formed as a RFID transponder. An independent claim is also included for a channel system.
