The Teren AVT Thermal Air Velocity Transmitter/Sensor is designed for air velocity monitoring and controlling, suitable for most HVAC applications. Based on the thermal anemometer principle, it uses an innovative and sensitive hot-film sensor, which is insensitive to dust and dirt, and easy to install and maintain. The transmitter has no moving parts, providing accurate, reliable, sensitive, and long-term measurement, with wide-range temperature compensation. Digital technology is applied to ensure output linearity and accuracy. Overvoltage and reverse polarity protection enhance reliability and anti-interference capacity. Multiple outputs are available, with an optional relay for alarm or ON/OFF control. The device features 4 field jumper selectable ranges: 0~5/10/15/20 m/s. An optional LCD and function keys support various functions such as parameter setting, modifying, and calibrating.
