SMP3 Pyranometer
The SMP3 is a smart pyranometer with low maintenance and industry
standard digital and analogue amplified outputs. Based on the proven
CMP 3 technology the SMP3 adds Modbus® interface, improved response time
and temperature corrected measurement data. The wide and low power
supply range from 5 to 30 VDC makes integration in meteorological
stations easy. The SMP is protected against over voltage, reversed
polarity and short circuiting. Because all SMP’s have identical
sensitivity and connections exchanging instruments during recalibration
is easy.
SmartExplorer Windows™ for data logging, display of data and Modbus® address setting is provided as standard.
SMP3 measures global solar radiation on a horizontal plane. When
tilted with the same angle as a PV panel it measures the tilted global
radiation, for PV module efficiency calculations.
