FS3000-1005

FS3000-1005 is a surface-mount type air velocity module that uses a MEMS thermopile-based sensor. The FS3000 features a digital output with 12bit 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. The application includes data centre and servers, HVAC and air control systems, laminar flow control systems, air filtration, and collection systems.
