In the industrial production environment, pressure gauge calibration plays an indispensable role in ensuring industrial safety. Many industrial equipments, such as boilers, pressure vessels, hydraulic systems, etc., rely on accurate pressure monitoring during their operation. If the pressure gauge is not calibrated or the calibration is inaccurate, it may lead to misjudgment of the internal pressure of the equipment. For example, when a boiler is in operation, if the pressure value displayed by the pressure gauge is lower than the actual pressure, the operator may continue to increase the fuel supply due to misjudgment, which will cause the boiler pressure to be too high and lead to serious safety accidents such as explosions; conversely, if the pressure value is displayed too high, it may lead to unnecessary shutdown and maintenance, affecting production efficiency. By regularly calibrating the pressure gauge and ensuring its measurement accuracy, reliable pressure information can be provided to the operator, enabling them to adjust the equipment operation parameters in a timely and accurate manner, effectively preventing safety accidents caused by abnormal pressure, ensuring the smooth and safe operation of industrial production, protecting the safety of people's lives and property and the normal production order of enterprises.
