Details

Advanced Sensor Technology

At the heart of the PYR1-485 lies a high-performance 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 high precision.

Sophisticated Digital Architecture

The PYR1-485 is equipped with an advanced electronics board featuring a microcontroller that manages:

  • Sampling and averaging of measurements
  • Temperature reading
  • RS485 transmissions

This digital architecture provides:

  • Exceptional noise immunity
  • Consistent behavior over time and temperature variations
  • Modbus RTU output over RS485, allowing for reliable signal transmission up to 500 meters

Innovative “Virtual Bubble Level”

Since 2022, the PYR1-485 has incorporated a high-precision inclinometer (14-bit resolution for X and Y inclinations), enabling a “virtual bubble level” feature. This can be accessed through the Allconfig program, allowing users to ensure perfect horizontal positioning. The inclinometer registers are published, enabling remote monitoring of the instrument’s orientation.

Robust Design for Outdoor Durability

Engineered for long-term outdoor deployment, the PYR1-485 features:

  • A double dome design with hemispherical optical glass, ensuring high 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 PYR1-485 undergoes rigorous calibration against a Secondary Standard (Class A Thermopile Pyranometer), which is rechecked every 12 months. This meticulous calibration process, compliant with ISO 9847 standards, ensures the highest level of measurement accuracy and traceability.

Optional Accessories

  • Customizable cable lengths: 3, 5, 10, 20 m
  • Bracket for Plane of Array installation
  • Bracket for pole installation
  • Albedo mounting kit (available upon request)
