The counterpieces for the process connections and the seals or sealing rings are not included in
the scope of supply for the thermometer. Liquiphant M weld-in adapters with associated seal
kits are available as accessories. →  35
Procedure in case of seal failure indicated by leak detection port:
• Disassembling of the thermometer, validated cleaning procedure of thread and sealing ring
groove
• Replacement of the seal or sealing ring
• CIP after re-assembly
In the case of weld-in connections, exercise the necessary degree of care when performing the
welding work on the process side:
• Suitable welding material
• Flush-welded or with welding radius > 3.2 mm (0.13 in)
• No recesses, folds or gaps
• Honed and polished surface, Ra ≤ 0.76 µm (30 µin)
As a general rule, the thermometers should be installed in such a way that does not impact
their ability to be cleaned (the requirements of the 3-A Sanitary Standard must be observed).
The Varivent ® and Liquiphant-M weld-in adapter enable flush-mounted installation.
