Core Features and 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 and 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 Pressure Resistance Equipped with elastic elements (Bourdon tube, diaphragm) and a safety relief cover, the robust structure can withstand certain pressure overloads and pulse impacts.

Frequently Asked Questions (FAQ)

What makes laser-welded pressure gauges superior to traditional threaded models?
Laser-welded pressure gauges achieve a permanent, airtight fusion between the casing and connector, completely eliminating leakage risks associated with aging seals or loose threads found in traditional threaded designs. The weld strength can match or exceed the base material, ensuring a more reliable and durable connection.
What is the IP protection rating of this pressure gauge?
By combining laser welding technology with sealed mirrors, this gauge typically achieves an IP65 or IP67 protection rating. This means it offers complete dust protection and can withstand water spray or short-term immersion without damage to internal components.
What connection types and locations are available?
The gauge is available with stainless steel connections in multiple locations: Lower, Center Back, and Lower Back. The standard thread size is 1/2" NPT, suitable for a wide range of industrial piping systems.
Is this gauge suitable for use in food, beverage, or pharmaceutical applications?
Yes. The all-stainless-steel construction, laser-welded sealed housing, and smooth surfaces make it ideal for aseptic processes in pharmaceutical, food, and beverage industries. The design supports easy cleaning and disinfection while maintaining the required hygiene standards.
Can this gauge handle pressure overloads or pulsating pressure conditions?
Yes. The gauge is equipped with elastic sensing elements including a stainless steel Bourdon tube and a safety relief cover. This robust construction enables the gauge to withstand pressure overloads and pulse impacts, making it well-suited for hydraulic systems, heavy machinery, and compressor applications.
How does the sealed design extend the service life of the gauge?
The laser-welded permanent seal keeps the internal cavity completely isolated from external moisture, dust, and contaminants. This prevents condensation buildup and internal corrosion of the movement and Bourdon tube, significantly prolonging the operational lifespan of the gauge even in harsh or humid environments.
