The FS3000 is a surface-mount type air velocity
module that uses a MEMS thermopile-based sensor.
The FS3000 features a digital output with 12-bit
resolution. The sensor comprises a “solid” thermal
isolation technology and silicon-carbide coating to
protect it from abrasive wear and water
condensation.
The module features a compact design fit for low
profile enclosures.
