JUMO __________________________________________________________________________ 37
When there is no alternative but to install the probe in the process
vertically,
the point of entry must be carefully insulated. The cable
must also be allowed to hang loosely as this prevents any condensed
water from running onto the probe along the cable.

Vertical Mounting of Probe
The following numbers refer to Figure 21:

=
Let the cable hang loosely. This prevents condensed water
running to the sensor along the cable.
NOTE
Please do not attach a heated probe (907023/337B) to metal structures
to avoid condensation problems caused by heat conduction along the
metal.
If the process temperature is much higher than that of the
environment, the whole probe and preferably plenty of cable must be
inside the process. This prevents measuring inaccuracy caused by heat
conduction along the cable.
When mounted on the side of a duct or channel, the probe must be
inserted from the side of the duct. If this is not possible and the probe
must be inserted from the top, the point of entry must be carefully
insulated.

Appendix A on page 163.
