What is the function of the cad cell in an oil burner?

The function of the cad cell in an oil burner is to prove ignition. This component is essentially a light-sensitive device that ensures that the oil burner has successfully ignited. When the burner operates, the cad cell detects the presence of a flame; if it does not detect a flame within a specified amount of time, it will signal the burner to shut down. This safety mechanism is critical because it prevents the accumulation of unburned fuel, which could lead to hazardous conditions, such as explosions or severe equipment damage. By actively monitoring the flame, the cad cell enhances the safety and efficiency of the oil burning process, allowing for reliable operation of heating systems.
