Single Point AV & Temp Transmitter AX-AV-SP-ESF-35-2
4-20mA / 0-10V - 0.5-8m/s & 0.5-16m/s 0-50 deg C
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).
For a steady control signal, damped output
Materials that prevent corrosion
