Advanced Sensor Technology
At the core of the PYR2-420 is a robust thermopile sensor, capable of measuring solar radiation across a broad spectral range of 300 to 2900 nm. This wide spectrum coverage ensures comprehensive solar radiation measurement, capturing both visible and near-infrared wavelengths with good accuracy.
Simplified Yet Effective Design
While featuring a simpler construction compared to Class B models, the PYR2-420 maintains the use of high-quality materials throughout. Its single dome design with hemispherical optical glass provides excellent protection and transparency, ensuring reliable measurements in various environmental conditions.
High-Performance Electronics
The PYR2-420 incorporates the same advanced electronics as its Class B counterpart, resulting in exceptional signal linearity and noise immunity. The sensor’s output is normalized to a 4-20mA current loop, offering several advantages:
- Simple two-wire cabling for easy installation
- High resistance to electromagnetic interference
- Reliable signal transmission over distances exceeding ten meters
These features make the PYR2-420 well-suited for a wide range of solar monitoring applications, from small-scale installations to larger solar farms.
Durable Construction for Outdoor Use
Engineered for long-term outdoor deployment, the PYR2-420 features:
- A single dome design with hemispherical optical glass, ensuring good transparency and protection
- An anodized aluminum body that withstands harsh environmental conditions
- Enhanced weather resistance for reliable operation in diverse climates
Precision Calibration and Quality Assurance
Each PYR2-420 undergoes careful calibration against a Secondary Standard (Class A Pyranometer), which is rechecked every 12 months. This calibration process, compliant with ISO 9847 standards, ensures a high level of measurement accuracy and traceability.
