TDFi- FA Electronic Fan Array Inlet Monitor

The TDFi-FA is a state-of-the-art electronic thermal dispersion type fan inlet air measurement device for reporting airflow and air temperature in fan array applications. The TDFi-FA host reads data collected from up to 16 monitor boxes with each monitor box gathering information from up to 4 sensors (1 or 2 sensors per fan); thereby offering the ability to collect a maximum of 32 airflow and temperature values from the fan array installation. Each fan has one or two sensors located in the fan’s inlet. The sensor’s design ensures minimal pressure drop by using less hardware across the fan inlet. Each sensor has a heated and passive thermistor. Up to 16 Client monitor boxes with max four sensors each can be connected to one host. The airflow and temperature information from each sensor is configured to correspond to the fan on which it is installed. This feature makes it possible to use only one Host as the interface point for processing air measurement from multiple fans on one or more AHU or RTU. The host will average up to 32 sensors on 16 fans when installed and configured as one airflow measurement station.
