Stainless steel sensor model SE21
Figure 26: Grounding connections
Ground the stainless steel model as shown in the figure. The
measuring medium is grounded via the adapter
1 and
additional grounding is not required.
Ground for devices with protection plates
The protection plates are used to protect the edges of the meter
tube liner, e.g. for abrasive media. In addition, they function as a
grounding plate.
• For plastic protection plates or piping with an insulating
liner, electrically connect in the same manner as a
grounding plate.
Grounding with conductive PTFE grounding plate
Grounding plates made of conductive PTFE are optionally
available for nominal diameter ranges of DN 10 to 250.
These are installed similar to conventional grounding plates.
