技术说明
CS300使用安装在经过余弦修正的头部的硅光电池检测器，提供可用于太阳能、农业、气象、水文等应用的太阳辐射测量。传感器使用Kipp & Zonen CM21热电堆型短波辐射仪来校准。CS300精确地测量300 到 1100 nm波长范围内的太阳和天空辐射。在该波长范围内校准的传感器不应该被使用在植被下方或人工光源下。
传感器的标准输出为 0.2 mV 每 W m-2，可在全太阳光照（1000 W m-2）时产生200 mV的信号。我们所有的数据采集器，包括CR200(X)系列，都可以测量CS300。

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 CS300 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.

-
Compare the sensor against a recently calibrated CS300-L on a clear, sunny day with the sun overhead. Ensure that the sensor being used as a reference is also level.
-
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.
-
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.
-
Campbell Scientific does not recommend splicing any cable into the existing cable. Splicing a cable could introduce water and electrical noise into the connection. The sensor can be ordered with longer cable lengths, and 50 m is right on the edge of the recommended length. With a cable this long, Campbell Scientific recommends measuring the sensor differentially using the following wiring conventions:
Wire Color
Data Logger Channel
RED
Diff Channel H
BLACK
Diff Channel L
CLEAR (SHIELD)
AG or Ground Symbol
JUMPER WIRE
Diff Channel L to AG or Ground Symbol
In the data logger program, a differential voltage instruction needs to be used instead of a single-ended voltage instruction.
