FS1015-1015

FS1015-1015 is a mass air velocity sensor module measures the air velocity using the thermo-transfer (calorimetric) principle. It offers key advantages over resistor based flow solutions. The sensor uses thermopile sensing, which provides an excellent signal-to-noise ratio. The sensor comprises a “solid” thermal isolation technology and silicon-carbide coating to protect it from abrasive wear and provides robustness and long-term reliability. The FS1015 design allows it to be mounted in a vertical or horizontal position. Applications includes HVAC and air control systems, data centre and servers, air filtration and collection systems, laminar flow control systems.
