PYR1-420 Thermopile pyranometers
PYR1-420 is a first class Thermopile Pyranometer according to the ISO 9060.
PYR1 – 420 is our new thermopile pyranometer for measuring solar irradiance in PV plants.
It is equipped with electronics to amplify a very weak signal coming from the thermopile and mounted with the best operational amplifiers on the market in terms of linearity, rejection to disturbances, consistent behavior over time and in temperature variations. The signal is normalized in the range 4 to 20mA.
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.
PYR1 – 420 is best for meteorological uses and for controlling the performance of photovoltaic systems when this is a requirement in EPC and O&M contracts.
