PYR2-420 – Class C Thermopile Pyranometer
PYR2-420 is an ISO 9060 Class C (Second Class) Thermopile Pyranometer.
It has a simpler construction than the Class B, but uses the same high quality materials.
As the Class C is equipped with the same electronics as the Class B, the signal has a high level of linearity and noise rejection. The signal is normalized in the 4 to 20mA range.
This analog output mode of the signal (current loop) is characterized by a simple wiring (cable with 2 wires), and a high immunity to electromagnetic interference and interference caused by distances of over ten meters.
This instrument is suitable for measuring solar power and monitoring the efficiency of photovoltaic systems when a precision of 5% – 10% is sufficient.
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.
