The pyrheliometer LP PYRHE 16 (First Class Pyrheliometer according to ISO 9060

classification) is an instrument for direct measurement of solar irradiance (Watt/m2).

The receiving surface must be positioned (via a solar tracker or else) perpendicularly

to sun’s rays. By using suitable diaphragms only the direct light reaches the surface

of the sensor. According to WMO (Seventh Edition 2008) and ISO 9069 regulations,

the pyrheliometer has a field of view of 5°.

The pyrheliometer is produced in three versions:

LP PYRHE 16 PASSIVE

LP PYRHE 16 AC ACTIVE with 4..20mA CURRENT output

LP PYRHE 16 AV ACTIVE with 0..1V or 0..5V o 0..10V VOLTAGE output to be defined at the time of placing the order
