LPPYRA-Lite pyranometer measures the irradiance on a flat surface (W/m2). Themeasured irradiance (Global Irradiance) is the sum of direct solar irradiance and diffuse irradiance.LPPYRA-Lite is a Spectrally Flat Class C (Second Class) pyranometer in accordancewith ISO 9060:2018 and with the criteria of the WMO “Guide to Meteorological Instruments and Methods of Observation’”.
The pyranometer is available in the following versions:
LPPYRA-Lite: PASSIVE. The passive version can be connected to the instrumentsD09847 and HD31 by using VP472 SICRAM module.
LPPYRA-LiteAC: ACTIVE with 2-wire (current loop) 4..20 mA output (0…2000W/m2).
LPPYRA-LiteS: With RS485 Modbus-RTU output.
LPPYRA-LiteS12: With SDI-12 output.The pyranometer is supplied factory calibrated.
The calibration is carried out inaccordance with the ISO 9847:1992 (type IIc) standard: ”Calibration of fieldpyranometers by comparison to a reference pyranometer”. The pyranometer iscalibrated by comparison with the reference sample calibrated annually at WRC (WorldRadiation Center).An optional fixing base integrating a levelling device is available as an accessory, forinstallations where horizontal positioning is required.
