概览
LI200X使用硅光电检测器测量全太阳和天空辐射。它直接地连接到我们的数据采集器，广泛用于太阳、农业和气象等应用。
优势与特点
- Compatible with most Campbell Scientific data loggers
- Calibrated for the daylight spectrum (400 to 1100 nm)
- Completion circuit in its cable standardizes calibration, allowing sensors to be interchanged without altering multiplier and offset values

技术说明
LI200X 使用固定在余弦校正过的头部的硅光电检测器来测量太阳辐射。校准参考是 Eppley精密光谱太阳辐射表（PSP）。LI200X 精确测量400 到 1100 nm波段内的全太阳和天空辐射。校准到这个波段的传感器不应当用在冠层下或人工光源中。，传感器的线缆上配有并联电阻，将微安信号转换成毫伏信号，这样LI190SB就可以直接由坎贝尔数据采集器来测量。
LI200X的线缆中包含环氧树脂封装的完成电路，标准化传感器的校准系数，使得无需改变乘数和偏移量值就可以互换传感器。
LI-200X传感器的标准输出是0.005 mV 每 W m-2，在全太阳辐射（1000 W m-2）下可提供5 mV的信号。我们所有的数据采集器，除了CR200(X)系列，都能测量该输出。

Additional Compatibility Information
Mounts
To ensure accurate measurements, the sensor should be leveled using a LI2003S leveling fixture, which incorporates a bubble level and three adjusting screws. The LI2003S leveling fixture mounts to a tripod or tower using the CM225 mount. For most applications, Campbell Scientific recommends attaching the CM225 to a CM202, CM204, or CM206 crossarm. The CM225 can also be attached to a tripod or tower mast.
Data Logger Considerations
One differential analog input channel per probe is required.
常见问题解答
LI200X-L: 2
-
The LI190SB-L measures photosynthetically active radiation (PAR), a spectral range of solar radiation from 400 to 700 nm. This is the energy that plants use during photosynthesis. Measurements with the LI190SB-L are reported as photosynthetic photon flux density (PPFD).
The LI200X-L measures total solar radiation from 400 to 1100 nm. Measurements are usually reported in units of W/m2.
-
The information included on a calibration sheet differs with each sensor. For some sensors, the sheet contains coefficients necessary to program a data logger. For other sensors, the calibration sheet is a pass/fail report.
