RTD_Sensor
The FMA1000 Series features dual linear analog outputs.



The FMA1000 Series industrial air velocity/ temperature transmitter/indicator from OMEGA (Stamford, CT) measures and displays air velocity as well as air temperature in research and development labs, HVAC applications, and other manufacturing processes. The sensor design is based on three RTD elements, one measures air temperature and the other two measure air velocity by measuring the heat loss from the RTD sensor as it cools down by the air flow. Features include:

  • Measures air velocities up to 50.8 m/sec (10,000 FPM).
  • Measures air temperature up to 121°C (250°F).
  • 1.5 percent full scale accuracy (velocity).
  • 0.5 percent full scale accuracy (temperature).
  • 3 different sensor probe configurations: fixed probe with top or back mount, or remote. Probe with 4.5 m (15') cable.
  • 250 msec response time, programmable up to 2 seconds.
  • Hot wire air velocity sensor design.
  • Economical 6 OD x 305 mm L (¼ OD x 12") insertion probe design.
  • Backlit LCD displays air velocity and air temperature simultaneously.
  • Air velocity and air temperature can be displayed in different engineering units.
  • Monitors maximum and minimum air velocity and temperature.
  • Dual linear analog outputs for air velocity and temperature.
  • High and low velocity alarm voltage outputs.
  • USB serial PC interface with windows based data logging PC application.
  • NEMA 4 (IP65) industrial enclosure.
