CSD 3 Sunshine Duration Sensor 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 Introduction 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 Meteorological agencies want to automate this process and Campbell-Stokes recorder, where a glass sphere focuses the reduce the variability of results. A very accurate solution is to sun onto a marked card and burns it when it is sunny. use a sun tracker and a pyrheliometer, but this is relatively However, the burn marks vary depending upon the material expensive. Therefore, Kipp & Zonen designed the CSD 3 and dampness of the card (high humidity or after rain). The Sunshine Duration Sensor. It is engineered for continuous card must be changed every day, the marks must be analysed outdoor use and is easy to install and service. It is used by major manually, and the results are highly subjective. national weather networks across Europe, and elsewhere.

Applications Sunshine Duration Sensors are widely used in weather 199 mm 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 294 mm 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...
