Specifications
Measurement Range
0-2000 PPM factory calibrated
Duct Air Velocity
0 to 1500 ft/min (0 to 450 meter/min)
Temperature Dependence
0.2% of full scale per ºC
Stability
<2% of full scale over the life of the sensor (10 years typical)
*Accuracy
±40 ppm +3% of reading @ 22ºC (72ºF) when compared with a factory
certified reference
Non-linearity
<1% of full scale @ 22ºC (72ºF)
Pressure Dependence
0.13% of reading per mm of mercury
*Calibration
Sensors will be calibrated at zero and span at the factory. Calibration in
the field will not be required. Sensors will be shipped with ABC Logic™
turned on.
Response Time
Three minutes typical for a 90% step change at low duct speeds
Sampling Rate
Every two seconds
Warm-up Time
< two minutes (operational); 10 minutes to achieve maximum accuracy
Certifications
RoHS compliance
FCC Part 15,B
CE EMC EN61000-6-2, class B, criterion B*
*Deviations of the output signal may occur during strong electrical fast
transients on the power line
Enclosure flammability rating – UL94-5VA
