Key Features & Advantages
Glycerin Filled Anti-Vibration Design
The glycerin filling reduces pointer vibration and ensures stable readings in pulsating systems.
Compact 50mm Industrial Size
Small dial design allows installation in compact equipment and OEM assemblies.
Stainless Steel Corrosion Resistant Case
SS304 housing ensures durability in humid and industrial environments.
Vacuum & Low Pressure Measurement Capability
Suitable for -1 to 1 bar vacuum systems and low-pressure monitoring applications.
EN 837-1 Standard Compliance
Manufactured according to international industrial pressure gauge standards for reliability and interchangeability.
Working Principle
The bourdon tube inside the gauge deforms under pressure or vacuum, converting mechanical movement into pointer rotation for real-time pressure indication.
