SMP11 Pyranometer

The SMP11 smart pyranometer combines class leading sensor technology with industry standard digital and analogue amplified outputs. Based on the proven CMP 11 technology the SMP11 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 for recalibration is easy.

PC Software for data logging, display of data and Modbus® address setting is standard provided.

SMP11 measures incoming global solar radiation with a 180° field of view. Ideal for solar radiation measurements in both Meteorological and Solar Energy applications that require the Modbus protocol or amplified outputs.

FAQ

  • What type of pyranometer can I use for my fixed PV panels farm?
    • For this application the CMP10 and SMP10 are advised as they have an internal drying cartridge that will last for at least 10 years.

      Please note that the pyranometer needs to be mounted in the same angle (POA) as the PV panel. 

       

      For users that prefer the desiccant visible Kipp & Zonen offers the CMP11 and SMP11 with visible and user changeable desiccant.
