RFS300

Board-Mount Digital Airflow Sensor (Reference Design)

The RFS300 is a board-mount air velocity and temperature sensor that uses a reference design circuit for maximum positioning flexibility, thereby creating the smallest possible sensor footprint (6mm x 6mm). The RFS300 is designed to be soldered directly to a printed circuit board or mounted to a surface mount socket for easy removal or maintenance.

Sensor element with pre-programmed IC

Drive circuit schematic and placement files supplied by Degree Controls, Inc.

Dual sensing element with protective shroud

Provides fully linearized air velocity and air temperature with wide operating range.

Smallest footprint sensor on the market

Less than 20mA power consumption.
Digital UART or I²C Communication
Alarm output option available for switch style operation
5% Accuracy & Repeatability Rating
Available flow learning command for product
optimization, post-soldering
