The Smart pyranometer SMP 10 (ISO 9060:2018 - spectrally flat, class A / formerly ISO 9060:1990 secondary standard) is based on the sensor technology from the CMP 10 in combination with a Smart interface.
The integrated bubble level is raised to the top of the housing and can be viewed without removing the snap-on sun shield, which also covers the signal cable connector.
The SMP 10 has an internal drying cartridge that will last for at least 10 years if the housing is not opened. This minimizes maintenance significantly.
From the individually measured temperature response, a specific polynomial correction function is calculated for the SMP10. This is loaded into the pyranometer memory and results in a very low change in sensitivity (± 2% max. for instrument temperature range from -40°C to +70°C, compared to the calibration temperature of +22°C).
The interval for dome cleaning can be extended and the quality of measurements maximized, by fitting the SMP 10 with a CVF 4 ventilation unit.
The SMP 10 has a RS-485 Modbus® RTU interface, 0 - 1 V or 4 - 20 mA analogue output, improved response time and temperature corrected measurement data. The wide and low power supply range from 5 to 30 VDC makes integration in meteorological and solar energy stations easy. The SMP 10 is protected against over voltage, reversed polarity and short circuiting.
Thanks to the standardized output and connections of every SMP 10, exchanging instruments for recalibration is easy.
SmartExplorer Windows™ software for data logging, display of data and Modbus® address setting, can be downloaded from the Kipp & Zonen / Ott HydroMet webpage.
