diffuser, its sensitivity is proportional to the cosine of the angle of

incidence of the radiation, thus allowing accurate and consistent

measurements. QMS101 has a ready-made cable with a connector, and

it is easily installed on the sensor support arm.

Figure 26 QMS102 Pyranometer

QMS102 Pyranometer is an ISO/WMO-classified second class

pyranometer. The precision optical glass dome acts as a filter, with a

spectral band-pass that permits the full solar spectrum to pass through

to the sensor. The sensor is a high-quality blackened thermopile with a

flat spectral response. Heating of the sensor by incoming solar radiation

produces a signal in the microvolt range.
