Why is it essential to calibrate pressure gauges on a boiler?

Calibrating pressure gauges on a boiler is essential to ensure accurate measurements for safe operation. Pressure gauges provide critical information about the internal pressure of the boiler, which is vital for the safe management of operations. If the gauge is not calibrated correctly, it may give false readings, leading to potentially dangerous situations. For example, if the pressure gauge indicates that the boiler is operating within safe limits when it is actually over-pressurized, this could lead to equipment failure or even catastrophic accidents such as explosions. Therefore, regular calibration ensures that the readings are reliable and enables operators to make informed decisions, maintaining safety and efficiency in boiler operation.
