Airflow Measuring Station
aluminum airfoil blade–thermal dispersion
AM-51-TD airflow measuring stations employ a low leakage control damper with highly accurate airflow measuring equipment in a single compact assembly. The C&S AC-51 control damper is factory mounted with a modulating 24V actuator and thermal dispersion airflow measurement system to provide airflow measuring along with the ability to control airflow all in one easy to install assembly. Fully encapsulated precision thermistors are paired with heating circuits and dedicated ELECTRA-flo G5 transmitters to provide a high degree of environmental protection along with state-of-the electronic airflow measurement.
