Air Velocity Transducers Heated for sfpm Measurements


Stamford, CT: Type FMA-900 transducers use a velocity and a temperature sensor to measure air velocity in standard feet per minute. Both sensors are rugged, glass-coated platinum resistance detectors. The circuit heats the velocity sensor to a constant temperature differential above ambient temperature and measures the cooling effect of the air flow, providing high accuracy and excellent low-velocity sensitivity. Linear analog 0-5 v dc or 4-20 ma outputs are provided for flows to 10,000 sfpm. Omega Engineering, Inc., (203) 359-1660
