3 .2 Process and environmental temperature
At high process temperatures a heat transfer to the terminal enclosure can be reduced by isolation of
the medium carrying part of the plant or by the use of a neck tube.
3 .2 .1 Neck tube
The neck tube is used to decouple the temperatures between medium and the terminal enclosure in
order to reduce the temperature at the terminal enclosure.
By using a neck tube at extreme process temperatures it can be achieved, that the permitted
environmental temperature range in the area of the terminal enclosure will not be exceeded.
The length of the needed neck tube depends on the height of the process temperature and the
respective installation situation.
Like shown in the graphic, the length of the neck tube can considerably influence the temperature at
the terminal enclosure.
The graphic is only an approximately guide, because the real heating of the terminal enclosure can be
influenced by additional factors, e.g. a system isolation or also the position of the terminal enclosure.
3 .3 Installation notes
Drive the system pressure free prior installation resp. deinstallation of the sensor.
Be sure that no medium is flowing in the system. At extreme system or medium temperatures there
could exist serious dangers.
The screw-in of the thread process connection by using the terminal enclosure, the connection plug
resp. the connection cable is not permitted.
The tightening of the thread process connection may only be done at the hexagon by a suitable
spanner and with the maximum permitted torque strength (see chapter „Technical data“).
