SR200-D1 Industrial Class A Pyranometer – High-Accuracy Solar Radiation Sensor

The SR200-D1 is an industrial-grade, fully digital Class A pyranometer designed for accurate measurement of hemispherical solar radiation. It is particularly suitable for photovoltaic (PV) performance monitoring, meteorological stations and demanding outdoor industrial environments. The instrument complies with ISO 9060:2018 Spectrally Flat Class A and IEC 61724-1:2021 Class A, making it a strong choice where reliable solar irradiance data is essential for evaluating PV system performance.

Typical Applications

The SR200-D1 can be applied in:

• Solar PV plant performance monitoring and PR evaluation.
• Meteorological and environmental monitoring stations.
• Solar resource assessment and energy studies.
• Industrial outdoor monitoring systems.
• Research and testing of photovoltaic modules.
• Applications requiring stable and traceable solar radiation measurements.

The measurement range is approximately -400 to 4,000 W/m², with a spectral response from about 285 to 3,000 nm. The digital Modbus RTU / RS-485 interface simplifies connection to PLC, SCADA, data loggers and PV monitoring systems.

SR Series Industrial Pyranometer Models

The SR200-D1 is intended for Class A PV monitoring in locations where dew and frost are not significant issues, while the heated SR300-D1 is designed for broader climatic conditions.

Advanced Technology for Accuracy, Safety and Reliability

One of the major advantages of the SR200-D1 is its industrial-grade design. It combines Class A measurement performance with electrical, environmental, EMC and safety protection intended for demanding outdoor installations.

The sensor features isolated RS-485 communication, an integrated humidity diagnostic and surge protection. Standard surge immunity is Level 2 / 1 kV, while the optional SPD01 can increase protection to Level 4 / 4 kV. A dedicated grounding terminal further supports electrical safety.
