B+B Thermo-Technik B + Technik rain detector &

The rain sensor can automatically control the operation of awnings or roof windows, for example. The switching polarity and sensitivity are adjustable. In the most sensitive setting, the device is also suitable for detecting fog. The optional mast or wall mount allows for easy installation.

The sensor area has been optimized to increase reliability in challenging conditions, such as during heavy rain. To ensure this, the tips of the sensor area now extend at an 80° angle rather than straight down. Additionally, the individual surfaces of the sensor area are now significantly narrower, allowing for more reliable detection of rain and snow. Along with the optimized sensor area, an automatic activation of the sensor heating has been integrated. This is only active when the sensor area is wet and serves to quickly dry the sensor area as well as to remove any remaining snow. Furthermore, an adjustable shut-off delay is now included in the rain sensor. This can be individually set according to requirements, ranging from approximately 90 to 330 seconds.

Areas of application:

• Agriculture and horticulture
• Control of ventilation flaps and roof windows
• Automatic switches for awnings and blinds
• Building management technology
• Weather stations.
