Air velocity transmitter
Sontay’s AV-622 air-velocity transmitter has its own built-in self-test feature and enables the user to manually over-ride the output to 0%, 50% or 100% to aid commissioning. The device comes in a flame-retardant housing with Sontay’s uniform style plant housing for fitting to ductwork
The output signal is selectable between 0 to 10 V DC and 4 to 20 mA, with user-selectable ranges.
These devices can operate in ambient temperatures from -10 to +50°C. Response speed is just 3 s with a 90% rate change.
