Hall effect sensor De Dietrich 7689700

The hall effect sensor is a magnetic field sensor used in heating equipment to detect rotation or position of components like flow turbines or motors. As part of burner spare parts, it provides essential feedback for system control and safety. This sensor is commonly found in gas burner systems to monitor fan speed or water flow. A faulty hall effect sensor can cause erratic operation or shutdown, making it a common replacement item during boiler maintenance.
