Why are pressure switches critical in boiler systems?

Pressure switches play a vital role in boiler systems by monitoring and controlling system pressure. These devices are designed to detect pressure levels within the system and can trigger alarms or automatically initiate shutdowns if pressure deviates from predetermined safe levels. This functionality is crucial for safety; excessive or insufficient pressure can lead to hazardous conditions, equipment damage, or failures. By ensuring that pressure remains within safe limits, pressure switches help protect both the boiler and operators, maintaining system integrity and safety while supporting reliable operation.

While pressure switches can indirectly influence operational costs, efficiency, and temperature maintenance through safe and stable operations, their primary function centers on pressure monitoring and control, which is why this option stands out as the key reason for their critical nature in boiler systems.
