Thermal Dispersion Probe Airflow Measuring System

The AV-ASTNN Thermal Dispersion Probe Airflow Measuring System Series averages velocity and temperature from up to four probes and sixteen sensing points in a duct or plenum, providing accurate, dependable airflow measure¬ment from 40 to 4,000 Feet Per Minute (FPM) (12 to 1,219 Meters Per Minute [MPM]) within ±2% accuracy. At each sensing point, a microprocessor calculates flow and temperature, sending this information to an Integral Multiplex¬ing Unit (IMU). The IMU collects data from each sensor circuit and sends a digital output to the control transmitter. The control transmitter provides air temperature and velocity information on an LCD screen and to a Building Automation System (BAS) through analog outputs (2 to 10 VDC or 4 to 20 mA).
