3.2.5 Separate version
Provide a separate version in the following cases:
Note:
•
Detector protection class IP 68
•
Fluid temperature > 100 °C
•
Strong vibrations
Caution:
•
Do not install the signal cable close to power cables, electric machines,
etc.
•
Fix signal cables. Due to capacity changes, cable movements may result
in incorrect measurements.
3.2.6 Grounding and potential equalization
In order to obtain an accurate measurement, detector and fluid need to be on the same
electric potential.
If flange or intermediate flange versions with additional grounding electrode are used,
grounding is provided by the connected pipeline.
Caution:
•
In case of a type with flange a connection cable (min. 4 mm²) between
grounding screw on the meter’s flange to the counterflange is to be used
in addition to the fixing screws. Verify that a perfect electric connection
is provided.
•
Color or corrosion on the counterflange may have a negative effect on
the electric connection.
•
In case of types with intermediate flanges, the electric connection to the
detector is done via two ¼ AMP plugs installed on detector’s neck.
