Compared to production systems, the pressure gauges are too small to cause any accidents. However, with the pressure gauge as the main device, the automatic interlocking device, the sensing device and the protection device as the supporting parts, the tiny and subtle visual perception, the fortress of safe construction is irreplaceable. "A thousand-mile-long dyke collapses in an ant's nest." Despising and ignoring details is a desecration of safety. As one of the safety accessories, the pressure gauge not only displays several pressure figures, but also monitors the smallest "leakage holes" with its smart "eyes", always guarding the door for product safety, personal safety and environmental safety. Especially when used in dangerous places such as production, storage, and transportation of flammable and explosive materials, explosive and toxic substances, and pressure factors play a key role in preventing catastrophic accidents. The contribution of pressure gauges to safety cannot be underestimated. First of all, users should continuously improve their safety awareness and sense of responsibility, and truly manage and make good use of the characteristics of the pressure gauge, so that it can play the role of "eyes"; second, the testing and verification agency should actively verify the pressure gauge and downgrade it in time. Pressure gauges that do not meet the requirements for use shall be scrapped to ensure accurate measurement values and reliable performance; at the same time, the regulatory authorities shall strictly supervise the use of pressure gauges, and investigate and punish illegal operations and illegal use in accordance with the law. Let us start from the details and foundation, light up the "eyes" of safety, and build a strong and safe long embankment together.
