The pressure gauge is a critical component in monitoring the operation of a low pressure boiler. It provides essential real-time information about the pressure within the boiler system. Maintaining the correct pressure is crucial for ensuring safe and efficient operation. If the pressure is too low, it may indicate that the boiler is not functioning properly, which could lead to inefficient heating or overheating. Conversely, excessive pressure can pose safety hazards, potentially leading to equipment failure or accidents. Therefore, the pressure gauge is vital for operators to assess the system's performance and take necessary actions to maintain safe operating conditions.

In contrast, while smoke detectors, water filters, and temperature sensors all play important roles in overall system safety and performance, they do not provide the specific information regarding the pressure levels that is essential for the safe operation of a low pressure boiler.
