Construction
- Solid-state design airflow sensor
- Measures airflow using the VORTEX method
- Vortex method is a proven way to measure the airflow very accurately
- Vortex method is independant of small particles present in the air stream - like water droplets
- The airflow sensor is housed in a stainless steel box
- The lifespan of the airflow detector can be in excess of ten years.
Advantageous characteristics
- Airflow speed maximum range of 40m/s or 144 km/hour
- Linear output proportional to airspeed
- Highly accurate, dependant on the width of the "accentuatar" bar
- Calibration is a function of the width of the bar
- Rapid response of change of airflow
- Excellent repeatability inherent to the vortex principles
- Very low lifecycle costs due to no moving parts
- Insensitive to small particles, dust or waterdroplets in the airstream
- Internal DIL switch for different ranges of airspeed
- Output is a standard 4-20mA
