The PYRAsense13 LPS13 is a premium Spectrally Flat Class A pyranometer, expertly engineered with an integrated, adjustable shadow ring. This sophisticated instrument precisely measures exclusively diffuse solar radiation by blocking direct sunlight throughout the day. It is an indispensable tool for advanced meteorological research, climate monitoring, and optimizing the efficiency of solar energy systems. With integrated diagnostics, multiple output options, and a robust IP67 housing, it delivers unparalleled, reliable data for critical environmental analysis.
Mastering the Measurement of Diffuse Solar Radiation
The LPS13 PYRAsense13 represents the pinnacle of precision in solar radiometry. Built upon our flagship LPS10 sensor, this instrument is designed for scientists, researchers, and engineers who require the most accurate data on diffuse solar irradiance. By utilizing its calibrated shadow ring to continuously block direct sunlight, it provides纯净 measurements of the sky's diffuse component. This data is vital for understanding cloud cover, atmospheric aerosol content, and the true solar energy potential of a location, forming the foundation for reliable climate models and optimized solar farm performance.
Smart Technology for Uncompromising Data Integrity
Beyond measurement, the LPS13 offers intelligent monitoring. Digital models are equipped with internal sensors that track temperature, relative humidity, and pressure inside the unit, allowing you to monitor its operating health and predict maintenance. A built-in days-of-operation counter simplifies service scheduling. An integrated bubble level and optional tilt sensor ensure your installation remains perfectly level and stable over time, guaranteeing data accuracy season after season.
Key Advantages of the LPS13 Pyranometer
- Integrated Shadow Ring: Enables continuous, accurate measurement of diffuse solar radiation without the need for complex sun-tracking systems.
- Comprehensive Internal Diagnostics: Monitor internal temperature, humidity, pressure, and operational days to ensure data reliability and plan maintenance.
- Effortless Installation & Setup: Integrated bubble level and configurable software (DATAsense) for easy levelling, real-time monitoring, and sensor configuration.
- Unmatched Accuracy and Compliance: Factory calibrated per ISO 9847, Spectrally Flat Class A per ISO 9060:2018, and compliant with WMO and IEC 61724-1 standards.
- Output Flexibility: Choose from various models with passive mV, 4...20mA, or isolated RS485 Modbus-RTU outputs with configurable analog ranges.
Optimal Application and Use
For precise data, correct installation is paramount. Use the integrated bubble level to ensure the sensor is perfectly level on a stable mounting structure. The optional tilt sensor is recommended for long-term installations to monitor any positional drift. Configure the analog output range and Modbus parameters using the dedicated DATAsense PC software. Regularly check the diagnostic data and days-of-operation counter via the software to schedule cleaning and maintenance, ensuring continuous, high-quality data acquisition.
