Thermal Dispersion Fan Inlet Sensor Airflow Measuring System

The AV-RA Series averages velocity and temperature from fan inlet sensors in a duct or plenum, providing accurate, dependable airflow measurement from 0 to 10,000 fpm (0 to 50.8 mps) within ±2% accuracy. Each sensor circuit is connected to a router that stores the calibration data. The router’s microprocessor calculates flow and temperature and sends this information digitally to the Electronic Controller, which provides air velocity and temperature informa¬tion on an LCD screen. The transmitter sends the output to a Building Automation System (BAS) through 4 to 20 mA or 2 to 10 VDC analog outputs (using a 500 ohm resistor) or a 1 to 5 VDC analog output (using a 250 ohm resistor).
