Installing the Sensor
Follow the instructions in this section to install your sensor. Before you begin, con-
sult the System Installation manual for instructions on labeling the sensor cable.
✦
For evapotranspiration (ET) or scientific measurements, the sensor can be
mounted on the Sensor Mounting Arm (SMA) or any level surface.
✦
For measurements where the immediate effect on humans is of interest, we recommend
that you mount the sensor such that its axis is aligned with the sun’s rays at solar noon.
This will maximize the mid-day readings and provide what is probably
a more accurate measure of the solar radiation people are exposed to.
The Health EnviroMonitor™ calculation of the solar radiation contribu-
tion to apparent temperature assumes that the sensor is tilted. The Sen-
sor Tilting Bracket #7706 is designed for this purpose.
✦ Similarly, if you wish to predict or monitor the irradiance on a solar voltaic or
thermal collection panel the data are probably most relevant if the sensor is tilted
to the same angle as the collection panel.
The Sensor Tilting Bracket #7706 is designed for this purpose.
Typical Standard Installation
The illustration below shows typical standard solar radiation installation. The
sensor cable attaches to connector S5 on the sensor interface module (SIM).
