Temperature sensors mounting
The temperatures indicated on the identication plate of the temperature
sensors are to be observed. The temperature sensors are always paired. Only
matched pairs are supplied and may not be separated, extended or shortened,
since this affects the measuring accuracy. With temperature sensor pairs with
a cable length longer than 3 m, we exclusively recommend the use of shielded
temperature sensor pairs. In this case, the shields must be installed correctly.
Temperature sensors with protection pockets must be inserted up to the stall –
and xed afterwards. With unequal cable lengths or longer than 6 m we recom-
mend exclusively the use of four-wire technology. The temperature sensors can
be installed alternatively in protection pockets or directly in the heating and/or
cooling agent however always both in the same way. Asymmetrical mounting,
one sensor direct the other with pockets, isn’t permitted. The measuring tip of
the temperature sensor part must be positioned in the center of the cross section
of the pipe.
