LPPYRA-Lite pyranometer measures the irradiance on a flat surface (W/m2). The measured 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 accordance with 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 instruments D09847 and HD31 by using VP472 SICRAM module.
- LPPYRA-LiteAC: ACTIVE with 2-wire (current loop) 4..20 mA output (0…2000 W/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 in accordance with the ISO 9847:1992 (type IIc) standard: “Calibration of field pyranometers by comparison to a reference pyranometer”. The pyranometer is calibrated by comparison with the reference sample calibrated annually at WRC (World Radiation Center).
An optional fixing base integrating a levelling device is available as an accessory, for installations where horizontal positioning is required.
