CNR4 Net Radiometer

FIGURE 3-2. Attaching the CNR4 onto the mounting rod

(CSI p/n 26120) using vertical pole or horizontal crossarm.

For installation in buildings or in solar energy applications, one will often have

to mount the CNR4 parallel to the surface that is being studied. This may be in

a tilted or a vertical position. The sensitivity of the radiometers will be

affected, but only in a minor way. This is specified as the so-called tilt effect.

From the specifications one can see that the tilt effect (this is a change in

sensitivity) remains within 1 % (See specifications in Section 2).

4. Using the Optional CNF4 Heater/Ventilator Unit

The optional heater/ventilator unit for CNR4 is available from the

manufacturer. You can purchase the CNF4-L heater/ventilator from Campbell

Scientific with custom cable length. Please refer to the Appendix B for details

on the CNF4 heater/ventilator, including the assembling instructions and

sample programs to control the CNF4 unit.
