4.6 Grounding the measuring sensor
4.6.1 Classical method
• The measuring sensor must be properly grounded.
• The grounding cable should not transmit any interference voltages.
• Do not use the grounding cable to connect more than one device to ground at the same time.
• The measuring sensors are connected to ground by means of a functional grounding
conductor FE.
• Special grounding instructions for the various measuring sensors are provided in the
separate documentation for the measuring sensor.
• The documentation for the measuring sensor also contain descriptions on how to use
grounding rings and how to install the measuring sensor in metal or plastic pipes or in pipes
which are coated on the inside.
DANGER!
There should be no difference in potential between the measuring sensor and the housing or
protective earth of the signal converter!
