3.3 Potential equalization
Perfect measurement is only ensured when the medium and the sensor have the same electrical
potential. Most sensors have a reference electrode installed as standard, which guarantees the
required potential connection. This usually means that the use of ground disks or other measures
are unnecessary.
• Promag L, Promag W and Promag P
Reference electrode available as standard.
•Promag H
– No reference electrode available. There is always an electrical connection to the fluid via
the metal process connection.
– In the case of plastic process connections, potential equalization must be ensured through
the use of grounding rings.
Standard situation
Potential equalization takes place via the ground terminal of the transmitter when using the
device in metal, grounded pipes.
