B+B Thermo-Technik GmbH

Illuminance measurement is the foundation for efficient building automation, productive agriculture, and safe industrial processes. To meet these demands even more effectively, the B+B brightness sensor with integrated transducer offers a comprehensive all-in-one solution.

Instead of having to decide on a measuring range in advance when purchasing, this new version provides the user with maximum flexibility. Three application-oriented measuring ranges can be configured directly on the device via switches: 0 ... 1,000 Lux, 0 ... 10,000 Lux, and 0 ... 100,000 Lux.

In addition to the 0 ... 10 V output voltage, a 0 ... 5 V output is available and included. Furthermore, the output voltage is invertible, making it particularly suitable for controlling LED controllers or dimmers. For control tasks, a switching output is provided, with a switching threshold that can be easily adjusted via a potentiometer.

As soon as the detected brightness exceeds the set threshold, the solid-state relay activates. If the light level drops 10% below the set value, the switching output deactivates. The IP65-rated enclosure provides reliable protection for the electronics. The B+B brightness sensor with transducer and switchable measuring range is ideal for a wide variety of applications, both indoors and outdoors.


Typical areas of application:
Building automation, lighting control
Brightness sensor for rain-protected weather stations
Brightness sensor for switching of appliances in applications with solar panels
Control of shading systems
Agricultural technology, brightness measurement in greenhouses
