Urdukas Pyranometer

At the AWS Urdukas station the CM6B Kipp&Zonen pyranometer is installed. It is mounted on a 2m pole.

The CM6B is a first class pyranometer as defined by the World Meteorological Organization. It is suitable for the measurement of solar irradiance on a plane surface (W/m2).

It incorporates a 64-thermocouple sensor, which is rotationally symmetrical, housed under K5 domes. A white screen prevents the body of the pyranometer from heating up. The pyranometer is supplied with a spirit level and screws for accurate levelling. A drying cartridge keeps the interior free from humidity.

The technical characteristics are:

- Spectral range 305...2800 nm (50%points)

- Sensitivity 9...15µV/Wm-2

- Impedance 70...100 Ohm

- Response time 1/e 5 s, 99 % 55 s

- Non-linearity <1.5 % (<1000 W/m2)

- Tilt error <1.5 % at 1000 W/m2

- Operating temperature -40...+90 °C

- Temperature dependence of sensitivity +/- 2% (-10...+40°C)

- Maximum irradiance 2000 W/m2

- Directional error <+/- 20 W/m2 at 1000 W/m2

- Weight 0.85 kg

- Cable length 10

Statement

The CM6B pyranometer is intended for routine global solar radiation measurement research on a plane/level surface.

Fully compliant with all ISO-9060 specification criteria for that if an ISO First Class pyranometer, the CM6B features a sixty-four thermocouple junction (series connected) sensing element.

The sensing element is coated with a highly stable carbon based nonorganic coating, which delivers excellent spectral absorption and long term stability characteristics.

The sensing element is housed under two concentric fitting Schott K5 glass domes.

Additional CM6B features include an integrated (built in) bubble level, reusable desiccant drying cartridge, white sunscreen, and a permanently attached shielded output signal cable.

The CM6B can be used in conjunction with the optional Kipp & Zonen CV2 ventilation system, for enhanced measurement performance and overall reduced instrument maintenance.

Every CM6B is calibrated upon manufacture, and is supplied standard with a WRR (World Radiometric Reference) traceable calibration certificate.
