6.2 Mounting
The NR01 has a hole suitable for a 1-inch IPS pipe (33 mm diameter) for
mounting the NR01 onto a CM204 or CM206 crossarm. The crossarm can be
mounted to any pole with a 25-mm to 54-mm outer diameter. However, for
most applications, Campbell Scientific recommends attaching the crossarm to a
CM310-series pole so that the sensor is above vegetation. You can also mount
the crossarm to the tripod or tower that supports the datalogger’s enclosure.
Slightly loosen the two bolts at the opposite end of the tube mount (4 in
) and rotate the sensor mount tube to level the sensor in the two
axes. Once the sensor is leveled, tighten all of the Allen bolts, restricting
further movement of the sensor.
gives other general guidelines for the positioning and installation
of the sensor.
