The role of a pressure gauge in a dry chemical extinguishing system is to display the amount of pressure within the system. This is crucial for several reasons. First, it allows users to monitor the pressure to ensure that the system is operational and ready to deploy the extinguishing agent effectively. Adequate pressure is necessary for proper distribution of the dry chemical during activation, as it directly affects the range and dispersion pattern of the agent when it is discharged.

Furthermore, maintaining proper pressure is essential for system integrity and reliability. If the pressure is too low, it may indicate a leak or that the extinguishing agent needs to be replenished, which could impair the system's ability to function in an emergency. Conversely, excessively high pressure could indicate a potential hazard or malfunction within the system.

In summary, the pressure gauge serves as a critical monitoring tool that helps ensure the dry chemical extinguishing system remains functional and can respond effectively in the event of a fire.
