The FST1000 Series measures air velocity and provides two SPST alarm contact closures corresponding to high and low alarm set points. The alarm set points are adjustable from 0 to 100% of the air flow range. The unit comes with a green power LED, and two red LEDs for high and low alarm indications. They can be used in research and development labs, HVAC applications, exhaust/ ventilation hoods and other manufacturing processes. The sensor design is based on RTD elements; the air velocity is measured by the heat loss from the RTD sensor as it cools down by the air flow. The sensor probe comes in two configurations, fixed mount and remote probe.
