GreenFlow GF Series GF-A1001-DI ATMD Product Data
●Typical Installations:
■Hospital, laboratory and clean room ducts
■Terminal boxes
■Outdoor air intakes to fan coils
■Makeup air ducts to air handlers
●The GF-A1001-DI airflow/temperature measurement device is a low cost, high performance, solution for airflow and temperature measurement in smaller round ducts. The GF-A1001-DI is provided with an integral transmitter. Simply provide 24 VAC/ DC power and connect the output cable wires to a BAS or other analog input device to determine the airflow rate and temperature.
●The GF-A1001-DI airflow/temperature measurement device is designed for duct insertion applications. Probes are available with one or two sensor nodes. Installed airflow accuracy is ±4% of reading to NIST traceable standards when installed in accordance to published placement guidelines.
●The GF-A1001-DI measurement device uses the principal of thermal dispersion to determine the airflow rate. Thermal dispersion is ideal for HVAC applications that typically require measurement of low air velocities. Each sensing node uses two thermistors to determine airflow. One thermistor is self- heated above ambient while a second thermistor determines the ambient air temperature. The power dissipated into the airstream is directly related to the airflow rate.
●Each thermistor body is a hermetically sealed bead-in-glass probe. Bead-in-glass thermistors have demonstrated extreme stability and superior performance over chip type thermistors used by other manufacturers. The bead-in-glass sensor used has been time tested for over 35 years by GreenTrol’s sister company, EBTRON. Thermistors are potted in a waterproof sensor assembly and are designed for years of trouble-free operation.
●Each sensing node is individually calibrated at 7 points in high- performance wind tunnels. The transmitter processes each individual sensor node independently. The result is the true average airflow rate and temperature when more than one sensing node is applied.
