RFS300

Board Mount Digital Air Velocity & Temperature Sensor


The RFS300 is a reference design, air velocity sensor, used by clients looking for both the smallest footprint, and lowest profile, board-mounted airflow sensor on the market.  The electronic circuit is implemented directly on the client’s PCB assembly, and Degree Controls provides the sensing head and the programmed micro-processor, on tape or reel, ready for reflow or soldering. For customers looking for a board-mount airflow sensor which is fully-integrated and packaged, and ready for plug-and-play on their PCB assembly, the F660 is a slightly larger, but optimal choice.

The RFS300 may be calibrated for flow velocities from 0.15 - 20 m/s (30-4000 fpm), with accuracy up to 5% of reading. The RFS300 sensor uses the smallest possible sensor footprint, (6mm x 7mm), to provide maximum positioning flexibility for the client. The sensor is powered by local 15-18VDC and communicates across the existing I2C or UART bus.  Fully addressable on the I2C bus, the RFS300 is ideal for multi-point applications.  The RFS300 may also be configured to operate as an open drain switch, to provide normally open or normally closed operation.For some applications, a flow learning command may be used, transmitted over I2C, to allow for local calibration of the sensor after install.
