PYR2-485 – Class C Thermopile Pyranometer
PYR2-485 is an ISO 9060:2018 Class C (Second Class) Thermopile Pyranometer ideal for scientific and meteorological use. It comes with RS485 Modbus output line suitable for distances up to 500m.
It has a simpler construction than the Class B, but uses the same high quality materials.
PYR2-485 – designed for accuracy and reliability
The PYR2-485 is equipped with electronics board with a microcontroller to manage sampling, average of sampling, temperature reading and RS485 trasmissions. This helps to guarantee rejection from disturbances and constant behavior over intervals of time and temperature variations. The output signal in in ModbusRTU over RS485.
The carefully selected components have a constant behavior over time and for a wide temperature range. The distances covered by the signals exceed 500 meters.
Note: the terms solarimeter, irradiance sensor, pyranometer and calibrated cell are interchangeable. On this site we will use irradiance sensor. To learn more click here.
This instrument is suitable for measuring solar power and monitoring the efficiency of photovoltaic systems when a precision of 5% – 10% is sufficient.
