5.1 Mounting
When the strap-on thermometer is mounted, the temperature must neither drop below
the permissible operating temperature (environment, medium) nor exceed it, even when
taking convection and heat radiation into account.
In order to keep the influence of the ambient temperature as low as possible,
we recommend that the measuring point is well insulated. In particular, for large
temperature differences between the medium being measured and the environment,
good insulation of the measuring point is essential.
5.2 Electrical connection
Only connect in an unpowered state!
Cables and wires
Fine-stranded conductors must be finished with end splices.
■
Cables used must comply with the respective requirements in terms of stability and
■
temperature.
Connection cables must be run so that any mechanical damage is prevented.
