Why Choose ROBIN as an Integrated Sensor?
- Professional radon sensor designed to be able to provide instantaneous values
- Can be installed in any direction
- Connects to a fan controller, PLC, or device suitable for analog input signals
- Able to be placed in ventilation ducts, air handling units, or just stationary in a room
- High sensitivity so a sufficiently good response time is achieved in the event of changes in radon content
- EMC protection and easy connection to thyristor control
Radonova has developed the radon sensor ROBIN, which measures radon concentration in air in Bq/m³ and provides an analog 1–10 V output proportional to the radon level. The sensor can be connected to a controller, PLC, or Building Management System (BMS) and used for applications such as fan control, automated ventilation, radon mitigation systems, and continuous indoor air quality monitoring.
Designed for fixed installation, ROBIN supports real-time monitoring and enables automated responses to elevated radon levels in residential buildings, commercial facilities, and technical installations, helping ensure a safe and controlled indoor environment.
Choose a Custom Measurement Range
One model of the sensor has a measuring range of 0–400 Bq/m³, where 10 V corresponds to 400 Bq/m³ and 1 V corresponds to 0 Bq/m³. An extended-range version is also available, offering a measuring range of 0–4,000 Bq/m³ with a 24 V output, designed for applications requiring higher concentration monitoring.
Quick & Easy Installation into BMS
The radon sensor is protected against electromagnetic interference and can be connected to a thyristor controller. The sensor is mountable without directional dependence and can be permanently installed in a room, ventilation duct, or air handling unit in a simple manner with no prior experience needed.
