WIKA operating instructions resistance thermometers and thermocouples, Ex n
GB
6.5 Parallel threads
If the thermometer connecting head, extension neck, thermowell or process connection are
connected with parallel threads (e.g. G ½, M20 x 1.5 ...), these threads must be secured using
seals which prevent liquids from penetrating into the thermometer.
As standard, WIKA uses copper prole seals for the connection between the neck tube and the
thermowell. If the thermometer and the thermowell are already connected, the seals will already
be mounted. The plant operator must check whether the seals are suitable for the operating
conditions and must replace them, if necessary, with suitable seals.
For thermometers without a thermowell, and/or where these are delivered separately, the seals
are not included and must be ordered separately.
Tighten the threads by hand when carrying out the nal assembly on the plant. This will
correspond to the delivery status of the premounted components. The nal tightening torque
should be applied using a spanner (half rotation).
The seals must be replaced after dismantling!
The seals can be ordered from WIKA, indicating the WIKA order number and/or the
designation (see table).
