The LP Silicon-PYRA 04. pyranometer measures the global solar radiation (W/ m2) by using a silicon photodiode (350nm-1100nm). The special geometry and the diffuser allow to have a pyranometer field of view of 180 degrees according to cosine law.
- LP Silicon-PYRA 04 with 5m fixed cable and open wires on the cable end, typical output 20 μV/(W/m2). Different cable lengths available upon request
- The photodiode current signal is converted into voltage through the shunt resistance
- The measurement of radiation across a surface is possible if the probe surface is a Lambert receiver
- The excellent concordance between the mesaured response and cosine law allows to use the equipment even when the sun has a very low elevation and the perform corrective actions throughout the year
The pyranometer is suitable for the measurement of natural sunlight. Under conditions of overcast sky or measures reflected light is recommended to use a thermopile pyranometer (model LP PYRA 03 or LP PYRA 02).
The LP Silicon-PYRA 04 pyranometer can be used in measurements of SOLAR RADIATION in the field of renewable energies such as solar thermal and solar photovoltaic.
The base with level LP BL (provided as an accessory) can be used to facilitate the assembly and placement in plan level.
The photocurrent generated by photodiode is converted into a voltage by the shunt resistance.
