Welding the transmitter into the pipe (weld nipple)
"
Caution!
Risk of electronics being destroyed. Please ensure that the welding system is not grounded via the
sensor or transmitter.
1. Secure the sensor using several welding points in the piping. A welding jig suitable for this
purpose can be ordered separately as an accessory → ä 94.
2. Loosen the screws at the process connection flange, and remove the sensor incl. seal from the
piping.
3. Weld the process connection into the pipe.
4. Mount the sensor back into the pipe. When doing so, make sure that the seal is clean and
positioned correctly.
!
Note!
• If the welding is done properly with thin-walled food pipes, the seal will not be damaged by heat
even when mounted. Nonetheless, it is recommended that you dismantle the sensor and seal.
• For dismantling purposes, it must be possible to open the piping a total of approx. 8 mm.
