General Information for Mounting HTS801 Sensing Probes
PLEASE NOTE
For accurate measurement it is of paramount importance to avoid T gradients along the probe. In case of
large T difference between the front and the back of the probe, it is highly recommended to insert the probe
completely into the process. Should this not be possible, place a thermal isolation layer on the part of the
probe outside the process (on the cable side).
PLEASE NOTE
The sensing probe must be mounted horizontally or vertically, pointing downwards. If possible, a drip sheet
should be fitted for each mounting.
PLEASE NOTE
For probe hanging onto its cable from the ceiling in applications where condensation is likely to happen it is
important to avoid condense water getting from the cable to the probe and into the sensing head. For this
use the drip water protection (see chapter
).
INSTRUCTIONS FOR INSTALLATION IN A HIGH-HUMIDITY ENVIRONMENT
If the process temperature differs significantly from the ambient temperature, the sensing probe should be
fully emerged in the process to avoid incorrect measurements and condensation problems on the sensor
head due to thermal conductivity.
It is recommended not to bring the sensing probe and colder metal parts in direct contact in order to avoid
condensation problems caused by thermal conductivity.
