Greenheck's AMD-TD series of thermal-dispersion-based airflow measuring dampers combines the functionality of a thermal-dispersion airflow station and a control damper to control airflow volumes to a target setpoint. Featuring Vari-Green airflow-measurement probes and transmitters, it measures airflow down to 100 fpm. Factory-supplied controllers are available with analog or BACnet MS/TP operation. The AMD-TD is available in four models: AMD-23-TD with 3V-style blades, AMD-33-TD with fabricated-airfoil blades, AMD-42-TD with extruded-aluminum blades, and AMD-42V-TD with vertically oriented extruded-aluminum blades.
