KIPP & ZOIMEIXI SINCE 1 S 3 □ FOR THE PRECISE MEASUREMENT OF SUNSHINE DURATION No moving parts Low maintenance at long intervals Low power consumption Suitable for remote stations Rugged and durable Sunshine duration is defined by World Meteorological Organisation (WMO) as the time during which the direct solar radiation exceeds the level of 120 W/m2, and is normally measured in hours. Traditionally, sunshine duration is monitored using a Campbell-Stokes recorder, where a glass sphere focuses the sun onto a marked card and burns it when it is sunny. However, the burn marks vary depending upon the material and dampness of the card (high humidity or after rain). The card must be changed every day, the marks must be analysed manually, and the results are highly subjective. Meteorological agencies want to automate this process and reduce the variability of results. A very accurate solution is to use a sun tracker and a pyrheliometer, but this is relatively expensive. Therefore, Kipp & Zonen designed the CSD 3 Sunshine Duration Sensor. It is engineered for continuous outdoor use and is easy to install and service. It is used by major national weather networks across Europe, and elsewhere.

Sunshine Duration Sensors are widely used in weather networks and holiday resorts to provide the number of sunshine hours per day for tourist information. In health spas and clinics they contribute to the measurements used in treatment and recovery. In agronomy the amount of sunshine received by crops can be used to help forecast yields. In building automation the CSD 3 can be used as an input to the systems for the control of the internal environment, such as the deployment of sun blinds. The Kipp & Zonen CSD 3 Sunshine Duration Sensor is rugged and durable and can be used at all...
