High Performance Board-Mount Digital Airflow Sensor

The F660 is the smallest form factor, digital airflow sensor available on the market today. Designed to measure spatial airflow inside electronic or ducted systems, the F660 uses high performance dual element sensing technology and can be soldered directly to a printed circuit board, or plugged into a surface-mount socket for easy removal or maintenance.  For customers looking for a lower profile head with sensor electronics built directly onto their PCBA as a reference design, the F660 is also available as a programmed sensing element called the RFS300. 

The F660 can be calibrated for flow velocities of 0.15 - 20 m/s (30-4000 fpm), with accuracy up to 5% of reading and operates from 0-60C.  Operating storage temperature range will not damage the part. The F660 sensor uses the smallest possible sensor footprint, (7mm x 10mm), thereby providing to maximum positioning flexibility for the client. The sensor is powered by local 15-18VDC and communicates across the existing I2C or UART bus, or can be configured with an alarm output, for switch-style operation. Up to 16 sensors can be addressed for applications where multipoint measurement is needed. Utilizing RoHS-compliant, dual sensing elements, the F660 sensor measures air velocity and air temperature in real time. For some applications, a flow learning command can be used, transmitted over I2C, to allow for local calibration of the sensor after install by the board manufacturer.
