• Isolate the sensor from cathodic protected pipes using insulated bolts.
• Use bypass cable between the mating flanges
Note
Remote mounted sensor versions
If the above is not acceptable, remote mounted sensors can alternatively be connected as
follows:
• Connect coil current cable shield at sensor end via a 1.5 µF condensator
• Make sure that electrode cable shield is not connected at both ends
4.2.6
Installation with grounding rings
NOTICE
Only sensors with PTFE or PFA liners without grounding electrodes
Installation with grounding rings is only relevant for sensors with PTFE or PFA liners
• Mount grounding rings where necessary on non-conductive pipes.
Installation with grounding rings on sensors with
PTFE liner
Note
Potential equalization
For potential equalization one grounding ring is sufficient.
By unidirectional flow it is recommended to mount the grounding ring on the inlet side.
• Connect the grounding rings to the sensor with the enclosed grounding straps.
