5.1 Installation
These resistance thermometers are designed for screw-fitting directly into
the process. The insertion length, along with the flow rate and viscosity of
the process media, may reduce the max. loading on the protection tube.
EN
If the resistance thermometer is to be operated in an additional
protection tube, a spring-loaded compression fitting must be used.
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 metal vessel, its components or pipes, and that these are
connected to the equipotential bonding system.
When there is a non-metal contact with the vessel, or with its
structural components or piping, the instrument must be provided with
equipotential bonding.
