The AX-AV-SP-ESF-35-2 is a single-point air velocity transmitter based on the calorimetric concept, which involves passing air flow through a heated thermistor and comparing the results to a control thermistor to calculate heat loss and associated airflow. The devices, which are positioned across the duct's flow, produce an analog output proportional to the airflow. A 0-10Vdc indication of the duct temperature is also included, and there are two-speed ranges accessible (jumper selectable).

    Features:

• For a steady control signal, damped output

• Materials that prevent corrosion

• 0-10Vdc Output of Duct Temperature Contains Pipe Flange

• 8 and 16 m/s are the two jumper-selectable speed ranges.

• Selectable Analog air velocity output
