6. Mount the process connection back on the sensor. When doing so, make sure to observe
the maximum screw tightening torques for lubricated threads: 7 Nm (5,2 lbf ft)

WARNING
Risk of destroying the electronics!
‣
Make sure that the welding system is not grounded via the sensor or transmitter.
1. Tack-weld the sensor to secure it in the pipe. A suitable welding aid can be ordered
separately as an accessory.
2. Release the screws on the process connection flange and remove the sensor, along with
the seal, from the pipe.
3. Weld the process connection into the pipe.
4. Reinstall the sensor in the pipe, and in doing so make sure that the seal is clean and in
the right position.
• If thin-walled pipes carrying food are welded correctly, the seal is not damaged by the
heat even when mounted. However, it is recommended to disassemble the sensor and
seal.
• It must be possible to open the pipe by approx. 8 mm (0,31 in) for disassembly.
Cleaning with pigs
It is essential to take the internal diameters of the measuring tube and process connection
into account when cleaning with pigs. All the dimensions and lengths of the sensor and
transmitter are provided in the separate "Technical Information" document.
