Modular quick coupling systems for level transmitters

Safe removal and exchange of signal converter without process interruption


When the signal converter of a radar or guided radar level transmitter needs to be replaced or upgraded, a process shutdown is often the obvious, yet most costly option that comes to mind to ensure occupational safety. This is especially true when pressurised tanks with toxic or flammable media are involved.


To avoid costly process shutdowns while providing the highest work safety, KROHNE radar and guided radar level transmitters feature a modular quick coupling system that allows a removal, exchange or 360° rotation of the converter without opening the tank and fully dismounting the level transmitter.

Safety benefits

  • High degree of occupational safety when servicing existing radar and guided radar installations on pressurised tanks

  • No service technician exposed to dangerous media when carrying out maintenance work

  • Safe retrofit or upgrade of previous level transmitters without fully dismounting the device or planning a process shutdown

  • Adapter system to upgrade existing radars to SIL-certified versions without process interruption 

  • Sealing and pressure containing components remain untouched during maintenance

  • Cost-efficient replacement of signal converter within seconds: no opening of the tank or removal of the flange system needed
