Series QAA2200 Room Temperature sensors are engineered to enable accurate and efficient control of room comfort. A wide variety of output signals is available for compatibly with nearly any control system. The patented housing design seamlessly blends into any décor and features strategically placed ventilation slots to maximize airflow and optimize accuracy.

A complete line of Duct Temperature Sensors with insertion depths of 4 inches up to 24 feet and a variety of output signals and measuring ranges enable compatibility with any HVAC control system.

Immersion Well Temperature Sensors monitor and transmit changes in liquid temperature to the HVAC control system. All sensors are fully assembled with stainless steel thermowells, and are available in 2.5-inch, 4-inch and 6-inch insertion depths.

Multiple output signals are available to ensure compatibility with most HVAC control systems.

Surface: Surface mounted temperature sensors are ideal for measuring pipe or vessel surface temperature as a surrogate for actual fluid temperature when it is not possible to retrofit a full immersion type sensor.

Cable: Low cost temperature sensors for use throughout the HVAC system. Cable temperature sensors typically used to measure temperature at the surface of a pipe. Also used to measure air temperature at the inlets or outlets of air handling devices or installed in thermowells to measure fluid or slab temperatures.

Outdoor Air Temperature Sensors monitor and transmit changes in outdoor air temperature to the HVAC control system. All sensors incorporate precision temperature sensing elements to accurately and reliably measure temperatures.

Duct Air Temperature Sensors monitor and transmit changes in duct air temperature to the HVAC control system. All sensors incorporate precision temperature sensing elements to accurately and reliably measure temperatures.
