PYR2-420 Thermopile pyranometers
PYR2-420 is a second class Thermopyle Pyranometer according to the ISO 9060.
It has an easier construction than the PYR1, but it is constructed with the same high quality materials used for the superior model.
This Second Class pyranometer is equipped with the same electronics used on the First Class Pyranometer so that 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 solar power measurements and for controlling the efficiency of photovoltaic systems when a precision of between 5% and 10% in solar energy actually received is sufficient.
