AHU Sensor Types and Locations

ACI offers complete sensor solutions for Air Handler Units and Roof Top Units. ACI’s sensor lineup includes: temperature, humidity, pressure, smoke detection, leak detection, freeze stats, IAQ and current sensors to cover all sensing aspects of AHU applications. This guide helps to show all the different sensor types and locations in an AHU. AHU designs vary based on application, performance, maintenance requirements, related size and building location, and energy efficiency. Based on the differences, not all sensor types apply. Regardless of AHU design, sensors are crucial to overall Indoor air quality (IAQ), energy use, and occupant thermal comfort.

Common Challenges

Air handlers require numerous sensors in multiple configurations to measure temperature, humidity, pressure, current, CO2, air quality, and more. Using field devices from different sources with varying quality standards and warranties can lead to lower overall efficiency of the BMS system and increased service calls.

The ACI Solution

ACI is a one-stop source for all of the sensors required for AHUs. Only one purchase order is needed. Most ACI sensors are American-made and backed by a five-year warranty. ACI's Sales and Technical Support Teams can help with difficult or unique installations.
