CSD3 Sunshine Duration Sensor

CSD3 Sunshine Duration Sensor

The CSD 3 is used for monitoring sunshine duration and automates the process previously undertaken by a traditional Campbell-Stokes recorder. The CSD 3 measures solar radiation through a high quality glass tube. It has no moving parts and uses 3 photo-diodes with specially designed diffusers to make an analogue calculation ...

LL-P-V External Light Level Sensor

External Light Level Sensors

The external light level sensors return a linear 0-10vDC signal representing the Lux level at the photo-diode cell based on the selectable Lux levels. The sensors are typically used to monitor external lighting levels to optimise energy efficiency through dimming and/or disabling lights as required. The LL-E-V is an external ...

Internal Light Level Sensors

These light level sensors return a linear 0-10vDC signal representing the Lux level at the photo-diode cell. The sensors are typically used in lighting strategies to optimise energy efficiency through dimming and/or disabling of lights as required or as sensors to monitor light levels over a period of time. The ...

Internal Light Level & Occupancy Sensors

The LL-C-M is a combined light level and occupancy sensor that can be used to control building lights based on occupancy and an adjustable light level. A passive Infra-red detector monitors occupation through moving body heat and a photo-sensitive device monitors the light levels. The sensors are typically used in ...

CSD3 Sunshine Duration Sensor

The CSD 3 is used for monitoring sunshine duration and automates the process previously undertaken by a traditional Campbell-Stokes recorder. The CSD 3 measures solar radiation through a high quality glass tube. It has no moving parts and uses 3 photo-diodes with specially designed diffusers to make an analogue calculation of when it is sunny. The output is switched high or low to indicate sunny or not sunny conditions. The calculated direct irradiance value is ...

LL-P-V External Light Level Sensor

External Light Level Sensors

The external light level sensors return a linear 0-10vDC signal representing the Lux level at the photo-diode cell based on the selectable Lux levels. The sensors are typically used to monitor external lighting levels to optimise energy efficiency through dimming and/or disabling lights as required. The LL-E-V is an external light level sensor with three different output ranges which can be selected using a link on the PCB. Selectable ranges are 10-2,000 and 10-10,000 Lux. ...

Internal Light Level Sensors

These light level sensors return a linear 0-10vDC signal representing the Lux level at the photo-diode cell. The sensors are typically used in lighting strategies to optimise energy efficiency through dimming and/or disabling of lights as required or as sensors to monitor light levels over a period of time. The LL-C-V is an internal ceiling mounted light sensor. Both units have a fixed range of 10-2,000 Lux and operate from a 24vDC power supply. ...

The LL-C-M is a combined light level and occupancy sensor that can be used to control building lights based on occupancy and an adjustable light level. A passive Infra-red detector monitors occupation through moving body heat and a photo-sensitive device monitors the light levels. The sensors are typically used in lighting strategies to optimise energy efficiency through controlling lights. The sensor is an internal ceiling mounted sensor with adjustable light level switching and an adjustable ...
