Part replacement
If the antenna, lens, secondary O-ring, and spring washers require replacement due to
damage or failure, they may be replaced without the need for re-calibration if of the same
type and size.
Replacing the antenna
Changing to a different antenna type may be performed by a Siemens authorized repair
center or personnel.
If the electronics or enclosure require replacement due to damage or failure, please ensure
the correct antenna version is used, otherwise a re-calibration will need to be performed by
Siemens authorized personnel.
Replacing the lens
1. Remove existing lens by turning it counter-clockwise until it separates from the unit.
2. Replace the O-ring between the lens and process connection with a new one.
3. Carefully thread the replacement lens, and turn it clockwise until resistance is encountered.
Do not over-tighten the lens, as this will permanently damage it.
4. For flange installation instructions, see Flanged versions (Page 25).
Note
After installation of the new lens onto the flanged encapsulated antenna version and before
mounting on the vessel/tank, some lenses may not appear to lie flush on the device, but this
is normal and will not impact performance.
See full operating instructions for part numbers.
