Product Description
The KNX Sensor Global Radiation SK08-GLBS-MES is a sensor / controller from the S8 product series which measures global radiation ( the sum at the point of measurement of both the direct and diffuse components of solar irradiance ). The sensor / controller has an offset sensor element which measures global irradiance in a horizontal position.
The device has an integrated KNX bus coupler and does not require additional voltage.
The transducer is located in a high-strength, extremely robust stable impact ABS plastic housing. Cover and base have a revolving groove and tongue system with neoprene gasket. The housing is IP65.
In the application software a separate controller ( 2-position or PI controller with continuous or pulsed output ) is available for every channel.
Other functions include maximum and minimum thresholds and a help key where the set point and thresholds can be switched.
The sensor is configured with ETS ( KNX Tool Software ) and the application program. Controlling functions such as signal threshold and diverse adjustments are set using ETS ( KNX Tool Software ).
Applications
- Surveillance Systems
- Watering Systems ( as a lock function )
- Observation of solar panels with a calculation of its efficiency
- Calculation of solar power
- Observation of greenhouses
