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.
