The primary function of duct and immersion temperature sensors is to detect temperature variations and transmit real-time data to control systems. This data allows HVAC and industrial processes to maintain consistent temperature levels, reducing energy consumption and improving operational efficiency. By continuously monitoring temperature fluctuations, these sensors help prevent issues like overheating, freezing, and inefficient energy use. https://www.building-controls.com/product-type/hvac-products/sensors/temperature/duct-and-immersion
