7 Shielding and Grounding

7.1 Equipotential bonding

The pyrometer housing is connected to the shielding via the cable connector!

Differences in ground potentials might cause an equalising current to flow between

devices through a cable shielded at both ends� In this case, be sure to install an

additional equipotential bonding line�

To avoid an equalising current, the pyrometer can be mounted electrically

insulated� The shielding must be connected to the plant’s earthing system�

If the pyrometer is installed without an insulator and with out potential

equalisation, the interference voltage may not exceed 32V�
