1. Clean sealing surfaces .
2. Put joint ring onto the sealing surface (make sure that the material of the joint ring is suitable for
the application in question).
3. Screw in the temperature sensor and fasten it with an open-end spanner 27 mm A. F. The torque re-
quired when cold is 150 Nm.
TRG 5-65, TRG 5-66, TRG 5-67 and TRG 5-68
1. Provide a penetration for the socket-weld end on site.
2. Unscrew the upper part of the temperature sensor from the welding sleeve .
3. Weld the welding sleeve in place. Arc-weld the equipment only manually in place, applying welding
process 111 and 141 in accordance with ISO 4063.
4. Put copper ring onto the welding sleeve and screw the upper part of the temperature sensor into the
welding sleeve . Fasten the upper part of the temperature sensor when cold with an open-end span-
ner (17 or 24 mm A. F.).
Only qualified welders certified according to EN 287-1 may weld welding sleeves into pres-
surized lines or vessels.
■ When installing the electrode in pipes weld the elbow onto the pipe, ensuring that the
temperature sensitive part of the temperature sensor is exposed to the fluid against
the flow direction. Fig.8 and Fig.9
■ Install the temperature sensor in such a way that the temperature sensitive part is per-
manently submerged in the fluid. Fig. 2 and Fig.4
■ Do not completely insulate the temperature sensors. See Examples of Installation Fig.6
and Fig.7
