What is the function of an oil pressure switch in an oil-fired plant?

The function of an oil pressure switch in an oil-fired plant is primarily to ensure safe operating pressure. This component is crucial for the protection of the entire system, as it monitors the oil pressure within the lines and equipment. If the pressure falls below or rises above predetermined levels, the switch can activate alarms or shut down the system to prevent unsafe operating conditions and potential damage.

Maintaining the proper oil pressure is vital for efficient combustion and optimal operation of the burners. If the pressure is not maintained, it can lead to insufficient fuel delivery or excess strain on the fuel system components. Therefore, the oil pressure switch plays a key role in safeguarding the integrity of the system by closely monitoring and controlling pressure levels, ensuring that the plant operates under safe conditions.
