SMP3 Smart Pyranometer

Quick Overview

The SMP3 Pyranometer is a second class pyranometer with an amplified analogue and RS485 Modbus RTU output. The SMP3 is identical to the CMP3 pyranometer but includes a Modbus interface allowing for an improved response time and rescaleable, temperature corrected measurement data. The amplified output options are 0-1V or 4-20mA and these are identically configured to allow for easy installation and exchange during recalibration. The SMP3 has a 4mm glass dome with a spectral range of 300 to 2800nm. The small size and sealed construction make this instrument perfect for monitoring solar energy installations, agriculture, horticulture, hydrological and industrial applications.

Details

The SMP3 is an entry level pyranometer with a completely sealed construction and non-replaceable drying cartridge. The SMP3 features a 64 junction thermopile sensing element with a highly absorptive, and spectrally flat black coating to capture incoming radiation and convert it to an electrical signal. This detector is protected from external influences by a high quality glass dome with is 4mm thick. However, the glass dome will require regularly cleaning to prevent a build-up of dirty, or salt spray in marine environments, which will obscure the sensor.

The SMP3 come with a 0-1V or 4-20mA analogue output and these can be rescaled by the user with the supplied PC software. The units are configured with the 0-1V output set as -200 to 2,000Wm² and the 4-20mA output as a 0-1,600Wm². Negative ranges are provided to allow the sensor to show levels at night when there is heat emitted from the sensor.

All SMP's have the RS485 Modbus RTU interface, very low power requirements and are supplied with comprehensive, traceable, calibration certificates. Calibrations are traceable to the World Radiometric Reference (WRR) in Davos Switzerland and are performed in accordance with ISO 9847, Annex A.3 'Calibration of Field Pyranometers by comparison to a Reference Pyranometer'.
