Absolute Sealing
Laser welding achieves a permanent fusion between the casing and the connector, eliminating any leakage points. This completely eliminates the risk of media leakage caused by aging seals or loose threads in traditional threaded pressure gauges.
High Structural Strength
The weld strength is close to or even exceeds that of the base material, resulting in an extremely secure connection with no possibility of loosening.
No Internal Leakage Risk
Eliminates the potential leakage hazard at the connection between the pressure-sensing tube and the movement in traditional pressure gauges.
High Protection Rating
Combining laser welding and sealed mirrors, the protection rating typically reaches IP65/IP67, providing complete dust protection and preventing water spray or short-term immersion.
Clean & Dry Internal Environment
The permanent seal achieved through laser welding ensures that the internal cavity is protected from external moisture and dust, preventing internal condensation and corrosion, and extending the lifespan of the core mechanism.
Overload / Pulse Resistance
Equipped with elastic elements (Bourdon tube, diaphragm) and a safety relief cover, the robust structure can withstand certain pressure overloads and pulse impacts.
