F300 / F333

Multi-Purpose Air Velocity Sensor


The AccuSense F300 Series uses our latest state-of-the-art constant ΔT technology to achieve accurate, stable, air velocity and air temperature measurements at a new best-in-market price point. The F300 provides airflow measurement over the velocity range 0.2 m/s to 10.0 m/s (40-2000 fpm).  Features include unimpaired access to tight locations, measurement accuracy to ±10% of reading from 15°C to 60°C, ease of installation, rugged construction, and probe interchangeability. Outputs are a linear 0-5V or 0-10V velocity output.  The optional UART or I2C (3.3v) serial communication provides air velocity as well as air temperature data. Typical applications include ducts & plenums.
