|

|
|
The AX-AV-SP range of single point air velocity transmitters are designed on the Calorimithric principle of the air flow being passed across a heated thermistor and the results being measured against the controlthermistor to determine heat loss and corresponding air flow. The units are mounted across the flow of the duct and give an analogue signal proportional to the air flow. |
