Double glass dome
Resumen
The SMP10-L pyranometer, manufactured by Kipp & Zonen and cabled by Campbell Scientific, measures solar radiation with a high-quality blackened thermopile protected by two glass domes. Its flat spectral sensitivity makes it ideal for applications in natural sunlight, under plant canopies, in greenhouses or buildings, and inverted to measure reflected solar radiation. Communications to on-site RTUs, SCADA systems, or other data acquisition systems are simplified with the industry-standard Modbus RTU communications protocol. Typical uses include environmental monitoring, solar resource assessment, and solar power performance applications.
Typically, this pyranometer is oriented perpendicular to the Earth’s surface to measure global horizontal irradiance (GH). Diffuse sky radiation can also be measured with the use of a shade mechanism.

Mounting
The SMP10-L should be mounted away from all obstructions and reflective surfaces that might adversely affect the measurement. The pyranometer has a bubble level and two leveling feet, which allow the SMP10-L to be leveled without using a leveling base.
The pyranometer typically mounts to a mast, crossarm, or pole (1.0 in. to 2.1 in. OD) via the CM255 or CM255LS mounting stand, assuming the heater/ventilator is not used. The pyranometer mounts near the end cap of an ATI or NexTracker torque tube via the CM260 or CM265 mounting kit, respectively.
The CVF4 Heater/Ventilator attaches to the 31153 Mounting Stand, which mounts to a crossarm or pole via the CM225 Right-Angle Mount or the 17953 Nu-Rail fitting.

SMP10 Example Programs v.1 (3 KB) 12-01-2021
Includes two CR1000X programs. One program measures the SMP10 sensor using Modbus over RS-485 and the other program measures the SMP10 analog voltage outputs. The Modbus program will store the measured value if the result code is zero, which indicates a properly working sensor. If the result code is not zero, NANs will be stored for the measurements.
