WARNING!
When the thermometer is mounted, the temperature must not drop below the
allowed operating temperature (environment, medium) or exceed it, even when
taking convection and heat radiation into account!
WARNING!
Before mounting the high-pressure thermocouple, check the metallic sealing
faces of the sealing cone and lens-type sealing ring for damage and separate
them, if necessary. During mounting, the tightening torques defined by the user
must be observed.
