The SMP3 is a smart pyranometer with an industry standard analogue and digital amplified outputs with low maintenance. The SMP3 adds a Modbus interface, improved response time and temperature corrected measurement data based on the proven CMP 3 technology. The wide and low power supply range from 5 to 30VDC makes integration in meteorological stations easy.
The SMP3 is protected against reversed polarity, voltage and short circuiting. Exchanging instruments during recalibration is easy as all SMPs have identical sensitivity and connections. PC Software for data logging, display of data and Modbus® address setting is provided. SMP3 determines 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.
The key features of the SMP3 pyranometer are:
- It has RS-485 Modbus® RTU interface
- 0 to 1V or 4 to 20mA analogue output
- Active temperature correction from -40°C to +80°C
