Description

The pyranometers LPPYRA13 measure the irradiance on a flat surface (W/m²).

The pyranometers are equipped with an adjustable shadow ring for the measurement of diffuse radiation only.
They are classified as Spectrally Flat Class A in accordance with ISO 9060:2018 (previuosly ‘Secondary Standard’) and according to the publication “Guide to Meteorological Instruments and Methods of Observation” of WMO.

The pyranometers are available in different versions:

LPPYRA13 – PASSIVE
LPPYRA13AC – ACTIVE with CURRENT 4..20 mA output. Measuring range: 0…2000 W/m² or 0…4000 W/m² (LPPYRA13AC4).
LPPYRA13ACS – double 4…20mA current output and RS485 serial output with MODBUS-RTU protocol. Measuring range: 0…2000 W/m² or 0…4000 W/m² (LPPYRA13ACS4).
LPYRA13AV – ACTIVE with VOLTAGE 0..1 V, 0..5 V or 0..10 V output. Measuring range: 0…2000 W/m² or 0…4000 W/m² (LPPYRA13AV4).
LPPYRA13S – with MODBUS RS485 output
LPPYRA13S12 – with SDI-12 output
