WARNING
Risk of destroying the measuring electronics!
►
Make sure that the welding machine is not grounded via the sensor or the transmitter.
1. Tack-weld the sensor into the pipe. A suitable welding jig can be ordered separately as an
accessory .
2. Loosen the screws on the process connection flange and remove the sensor, complete with
the seal, from the pipe.
3. Weld the process connection to the pipe.
4. Reinstall the sensor in the pipe. Make sure that everything is clean and that the seal is
correctly seated.
• If thin-walled foodstuffs pipes are not welded correctly, the heat could damage the
installed seal. It is therefore advisable to remove the sensor and the seal prior to welding.
• The pipe has to be spread approximately 8 mm (0.31 in) to permit disassembly.
Cleaning with pigs
If pigs are used for cleaning, it is essential to take the inside diameters of the measuring tube and
process connection into account. All the dimensions and lengths of the sensor and transmitter
are provided in the separate documentation "Technical Documentation".
Mounting the seals
!
CAUTION
An electrically conductive layer could form on the inside of the measuring tube!
Risk of measuring signal short circuit.
