Core Features & Advantages
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.
Typical Application Fields
Petrochemical & Natural Gas Pressure monitoring of pipelines, reactors, compressors, and storage tanks.
Pharmaceutical & Food & Beverage Aseptic processes with high hygiene and cleanliness requirements; easy to clean and disinfect.

Frequently Asked Questions
Q What makes laser-welded pressure gauges more reliable than traditional threaded gauges?
Laser welding creates a permanent, metallurgical bond between the casing and connector, eliminating all threaded joints that can loosen or degrade over time. This results in zero leakage points, superior structural integrity, and a weld strength that meets or exceeds the base material — making the gauge significantly more reliable in demanding environments.
Q What is the IP protection rating of this pressure gauge?
By combining laser welding technology with sealed mirror glass, this pressure gauge typically achieves an IP65 or IP67 protection rating. This means it is fully dust-tight and protected against water jets (IP65) or short-term immersion (IP67), making it suitable for harsh outdoor and industrial environments.
Q What thread standard and connection locations are available?
This gauge uses a 1/2" NPT thread connection. It is available in three connection locations: Lower (bottom mount), Center Back, and Lower Back — providing installation flexibility for a wide range of pipeline and panel configurations.
Q Is this pressure gauge suitable for use in corrosive or hygienic environments?
Yes. The case, ring, connection, Bourdon tube, and movement are all constructed from stainless steel, offering excellent corrosion resistance. The fully sealed design also prevents external contaminants from entering the gauge, making it appropriate for pharmaceutical, food and beverage, water treatment, and marine applications where hygiene and corrosion resistance are critical.
Q Can this gauge handle pressure overloads or pulsating pressure conditions?
Yes. The gauge is equipped with a stainless steel Bourdon tube as the primary sensing element, along with a safety relief back cover. This robust construction allows the gauge to absorb and withstand certain levels of pressure overload and pulsating or dynamic pressure conditions, which is particularly beneficial in hydraulic systems and compressor applications.
Q How does the sealed internal environment extend the gauge's service life?
The laser-welded permanent seal isolates the internal mechanism from external humidity, dust, and contaminants. This prevents moisture ingress that can cause internal condensation, corrosion of the movement and Bourdon tube, and dial deterioration. By maintaining a clean, dry internal environment, the gauge's core components are protected from premature wear, significantly extending its operational lifespan.
