10. Sensor Support Arm
Installation
10.1 Overview of Sensor Support Arm
Installation
Before starting the installation, plan carefully how many sensor support arms you need and
where to install them. The number and positioning of sensor support arms depends on the
sensors that you are going to install.
The sensor support arm is a horizontal bar that is used for mounting the following types of
sensors:
• Humidity and temperature probe
• Present weather detector
• Solar radiation sensors
• Wind sensor
Sensor support arm DKP060SUP is used for short pole masts, whereas DKP12SUP is used for
long pole masts, the frangible pole mast, and the frangible lattice mast.
For most sensors, WMO recommends installation at 2 m (7 ft) from ground level. Install the
sensor suppor arm as close to this height as possible. Take also into account the mast type:
on a tiltable mast, install the sensor support arm so that it does not prevent lowering and
erecting the mast.
For
sensor-specific guidelines on positioning and aiming the sensor, see the sensor
installation instructions.
To prevent corrosion and oxidation, use copper paste or equivalent on screws and
connector threads.
