LI200X Pyranometer
The black outer jacket of the cable is Santoprene
®
rubber.
This
compound was chosen for its resistance to temperature extremes,
moisture, and UV degradation.
However, this jacket will
support combustion in air.
It is rated as slow burning when
tested according to U.L. 94 H.B. and will pass FMVSS302.
Local fire codes may preclude its use inside buildings.

Installation
The LI200X should be mounted such that it is never shaded by the
tripod/tower or other instrumentation.
The sensor should be mounted with the
cable pointed towards the nearest magnetic pole, e.g. in the Northern
Hemisphere point the cable towards the North Pole.
Mounting height is not critical for the accuracy of the measurement.
However,
pyranometers mounted at heights of 3 m or less are easier to level and clean.
To ensure accurate measurements, the LI200X should be mounted using
LI2003S base/leveling fixture.
This base incorporates a bubble level and three
adjustment screws.
The LI200X and base/leveling fixture are attached to a
tripod or tower using one of three mounting configurations (see Figure 2-1
through 2-3).
Tools required for installation on a tripod or tower:
Small and medium Phillips screwdrivers
5/32” Allen wrench for NU-RAIL (Figure 2-3)
1/2” open end wrench for 015ARM or CM225 (Figures 2-1, 2-2)
Tape measure
UV-resistant wire ties
