Selecting Location
Select a place with stable conditions for mounting the transmitter. Do not
expose the transmitter to direct sunlight or rain. A rain shield is available
and it is recommended for direct outdoor installations. When mounting the
probe, select a place representing the process conditions.
General Instructions for Probes with
Cable
Mount the probes with a cable horizontally; this way, any water
condensing on the tube cannot flow onto the sensor.

Horizontal Mounting of Probe
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.
