Thermal Dispersion

Thermal dispersion probes with control damper

Thermal dispersion technology uses an array of thermal dispersion nodes positioned across the face of a duct or opening. The AMD-TD series combines the function of Vari-Green® airflow measurement probes and transmitters with a low-leakage control damper into one compact assembly. These measure and control airflow volumes to a target set point.

AMD-23-TD
