R290 Refrigerant Infrared Sensor
The Senseair Sunlight R290 features an electronic design with no moving parts, making it superior vibration resistance and rugged durability. This solid-state design offers significant advantages for applications that are exposed to harsh environments or where there is a risk of explosion. It is also the first NDIR sensor to feature LED technology, which is a true energy saving while maintaining high accuracy.
The Senseair Sunlight R290 is designed for mass production and enables full traceability of all processes and critical components through the sensor serial number.
Each sensor is individually calibrated and offers a UART (Modbus) and I2C interface. When the ABC function is enabled, the sensor is maintenance-free.
The modular design allows for easy integration into a wide range of products. Senseair Sunlight R290 can be used in a wide range of R290-based refrigerant applications.
