Page 6: Measuring Principle
LPS05 / LPS11 - Albedometers V1.0 3 Measuring principle The two pyranometers composing the albedometer are independent and are based on a thermopile sensor. The thermopile sensitive surface is coated with a black matt paint, which allows the pyranometer not to be selective at different wavelengths. -
Page 7: Installation
LPS05 / LPS11 - Albedometers V1.0 4 Installation • The albedometer should be placed at a height of 1-2 m above the ground. In the case of grassland, the height of the grass should be kept constant throughout the year. In snowy regions, care should be taken to adjust the height of the instrument so as to keep the distance from the blanket of snow constant. -
Page 8: Electrical Connections
LPS05 / LPS11 - Albedometers V1.0 4.1 Electrical connections Warning! The metallic housing of the two pyranometers should preferably be grounded locally. The CPM12… cable shield is connected to the connector shell and then to the metallic housing of the pyranometer. Do not connect the yellow/green wire (cable shield) to ground, unless it is not possible to ground the pyranometer metallic housing locally via the support mast. -
Page 9: Measurement
LPS05 / LPS11 - Albedometers V1.0 5 Measurement The pyranometers are distinguished by the sensitivity (or calibration factor) S expressed in µV/(Wm ), shown in the label on the sensor and in the calibration report. The irradiance E is obtained by measuring with a multimeter the difference of potential... -
Page 10: Maintenance
LPS05 / LPS11 - Albedometers V1.0 Maintenance In order to grant measurements high accuracy, it is important to keep the outer glass domes clean. Consequently, the more the domes will be kept clean, the more measure- ments will be accurate. -
Page 11: Safety Instructions
LPS05 / LPS11 - Albedometers V1.0 Safety instructions The albedometer proper operation and operating safety can be ensured only in the climatic conditions specified in this manual and if all standard safety measures as well as the specific measures described in this manual are followed. -
