5.1 Mounting
This compact temperature transmitter is intended to be screwed directly
into the process. The insertion length, along with the flow velocity and
viscosity of the process media, may reduce the max. loading on the
thermowell.
The case must be grounded against electromagnetic fields and
electrostatic charge. It is not necessary to connect the case separately to
the equipotential bonding system, provided that it has a fixed and secure
contact to the metallic vessel, its components or pipes, and that these
are connected to the equipotential bonding system.
When there is a non-metallic contact with the vessel, or with its
structural components or piping, the instrument must be provided with
equipotential bonding.
