技术说明
The CS301 uses a silicon photovoltaic detector mounted in a cosine-corrected head to provide solar radiation measurements. Its dome-shaped head prevents water from accumulating on the sensor head. To eliminate internal condensation, the sensor head is potted solid and the cable is shielded with a rugged Santoprene casing. The CS301 is calibrated against a Kipp & Zonen CM21 thermopile pyranometer to accurately measure sun plus sky radiation.

Additional Compatibility Information
Sensor Mounts
Accurate measurements require the sensor to be leveled using a 18356 leveling fixture. This leveling fixture incorporates a bubble level and three adjusting screws. The 18356 mounts to a crossarm or a tripod or tower mast using the CM225 mounting stand. The CS301 should be mounted away from all obstructions and reflective surfaces that might adversely effect the measurement.
Data Logger Considerations
One differential analog input channel per probe is required.

-
No. The CS301CBL is used with the CS301.
-
No. It’s not the range that makes a sensor a quantum sensor. It is the type of light filter used with the photocell that only allows specific wavelengths of light in the PAR frequency range to strike the photocell.
-
The leveling base provides physical stability and helps ensure the sensor is leveled correctly. It is not recommended to use the sensor without the base. The sensor mounts to the base with an included bolt. However, a user-supplied plate with a hole drilled in it could be used instead to accept the sensor’s mounting bolt.
Note: Whatever mounting method is used, the sensor has to be levelled to operate correctly.
-
Compare the sensor against a recently calibrated CS301 on a clear, sunny day with the sun overhead. Ensure that the sensor being used as a reference is also level.
