The AVT4 Air Velocity Transmitter measures air speed in HVAC ducts with high precision. It uses a professional hot-film sensor to provide accurate data for your ventilation system. This tool helps you manage airflow in commercial offices, laboratories, and cleanrooms. It ensures your system provides the right amount of fresh air to every room. By tracking air speed, you can improve indoor comfort and reduce energy waste. You can view our full range of airflow sensors here.
Benefits of the AVT4 Air Velocity Transmitter
This model offers many selectable range options to fit your specific needs. You can set the range to 0–5, 10, 15, or 20 meters per second. You can select these ranges easily using a simple internal jumper. This flexibility makes the device suitable for many different air duct sizes and speeds. The hot-film technology ensures the sensor remains stable over a very long period. To learn more about airflow standards in buildings, visit the AMCA website.
High Precision and Fast Response
The AVT4 Air Velocity Transmitter reacts to changes in air speed very quickly. It has a typical response time of only two seconds. This speed allows your HVAC controller to adjust fan speeds immediately. The device maintains its high accuracy even if the air hits the probe at an angle. The angle dependence stays below 3% for most typical installations. This feature makes the sensor very easy to install in tight or difficult duct spaces.
Integrating the AVT4 Air Velocity Transmitter
Setting up this transmitter is quick and simple for any HVAC technician. The durable probe fits into standard ductwork without any special tools. You get precise readings even in low-flow environments where other sensors often fail. This device helps you lower operating costs by optimizing your air delivery. It provides the data you need to maintain a perfect indoor climate for all building occupants. Professionals trust this transmitter for its reliability and its very long service life.
