Description
AVT-D-R
Electronic air velocity and temperature transmitter for air and non-flammable gases with relay output and Display | AVT-D-R
The air velocity transmitter is designed for use in building automation in the HVAC/R industry. The AVT measures air velocity and temperature, with selectable range and output options in a single device. Designed with a probe and adjustable flange suitable for round or rectangular ducts.
Features:
Separate measurements and outputs for air velocity and temperature
Proportional output options: voltage (0…10 V) and current (4…20 mA)
PID controller for air velocity (-D models)
Three field-selectable measuring ranges for air velocity, selectable with jumpers (models without Display)
Freely selectable measuring range for air velocity via menu (-D models)
Field-selectable units (-D models):
Air velocity: m/s, ft/min
Temperature: Celsius, Fahrenheit
Options:
Display (-D models)
Adjustable relay (-R models)
Modbus (-MOD models)
