Maximizing HVAC Efficiency with Duct Averaging Sensors

The heart of an effective HVAC system lies in the precise management of temperature throughout extensive ductwork. This is where duct averaging sensors come into play. Designed for the meticulous task of maintaining an even and comfortable ambient temperature, these sensors are integral to modern heating, ventilation, and air conditioning systems.

Duct averaging sensors are specially designed to measure temperature over the length of an air duct. Unlike point sensors that measure temperature at a single location, duct averaging sensors provide a more comprehensive overview by measuring the temperature along the entire length of the sensor probe. This is particularly useful in large and complex duct systems where air temperatures can vary significantly due to stratification, airflow patterns, or other factors.

Belimo’s new line of duct averaging temperature sensors, such as the 22MT-528 (active, 0...5 V, 0...10 V, ), 01MT-5B8 (passive, Pt1000), and 01MT-5L8 (passive, NTC10k (10k2) are engineered to deliver exceptional performance. These sensors are housed in rugged IP65 / NEMA 4X rated enclosures, ensuring they are well protected from environmental factors and capable of operating in diverse conditions.

The most recent addition to our 50-foot averaging sensor line is the 22MT-548. This variant features a 4…20 mA active output, delivering precise and reliable temperature readings for complex HVAC application

Applications and Use Cases

Air Handling Units (AHUs): For AHUs, duct averaging sensors assist in achieving the desired mix of recirculated and fresh air, which is vital for both comfort and energy savings.

Zonal Temperature Control: In buildings with multiple zones requiring different temperature settings, duct averaging sensors can ensure each zone receives air at the correct temperature.

Overall Energy Efficiency: Maintaining the correct temperature is key to energy efficiency. By providing accurate temperature readings, these sensors help the HVAC system to operate only as needed, reducing energy consumption.

Installation Flexibility

With probes available in various lengths, including the extensive 50-foot option, Belimo duct averaging sensors offer flexibility when it comes to installation. They can be mounted horizontally or vertically, catering to the specific design of the ductwork.
