It uses a thermistor sensing element to monitor mixed air temperature inside ventilation ducts. The sensor operates on a negative temperature coefficient (NTC) principle, meaning its electrical resistance decreases as the sampled air temperature rises. This resistance change is read as an input signal by compatible economizer logic modules to proportion outdoor and return air dampers. HVAC technicians and building automation professionals rely on this type of sensor to maintain proper mixed air temperature control, which is essential for energy-efficient economizer operation. The c7150b1004 is compatible with Honeywell and Resideo control modules including the W973 and M7415 actuators, as well as the W7210, W7212, W7213, W7214, W7215, W7459, and W7460 economizer logic modules. This broad compatibility makes it a practical replacement or service part for a wide range of commercial HVAC economizer applications. The sensor requires no field calibration or settings adjustments, which simplifies installation and reduces commissioning time. It mounts directly to the outside of the duct surface using four screws, which are not included. The sensing element is rated at 3000 ohms at 25 degrees Celsius and operates across a temperature range of 40 degrees Fahrenheit to 110 degrees Fahrenheit, covering typical mixed air conditions found in commercial air handling units. This sensor is a direct fit for systems requiring a reliable NTC thermistor input for demand-controlled ventilation and free cooling economizer logic. It is a standard service part for commercial HVAC service contractors, controls technicians, and facilities maintenance teams working on economizer-equipped air handling systems.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eSolid-state NTC thermistor sensor rated at 3000 ohms at 25 degrees Celsius for precise mixed air temperature measurement\u003c\/li\u003e\n\u003cli\u003eNo calibration or settings required — installs and operates immediately upon mounting\u003c\/li\u003e\n\u003cli\u003eCompatible with W973, M7415, W7210, W7212, W7213, W7214, W7215, W7459, and W7460 economizer control modules\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eProduct Highlights\u003c\/h4\u003e\u003cp\u003eThe Resideo Braukmann c7150b1004 mixed air sensor provides reliable NTC thermistor-based temperature sensing for commercial HVAC economizer systems.
