Introduction to EN 837-1 Standard

The EN 837-1 standard governs the design, construction, and accuracy of Bourdon tube pressure gauges. The standard ensures that these gauges are safe, reliable, and consistent across different manufacturers and applications.

Detailed Specifications of EN 837-1

Key parameters defined in the EN 837-1 standard include:

• Nominal Sizes: Typically 40mm, 50mm, 63mm, 100mm, 160mm, and 250mm.
• Pressure Ranges: From 0-0.6 bar up to 0-1,600 bar, depending on the specific gauge design.
• Accuracy Classes: Common classes are 0.1, 0.25, 0.6, 1.0, 1.6, 2.5, and 4.0, where lower numbers indicate higher accuracy.
• Operating Temperatures: Generally -20°C to +60°C for ambient temperatures, with process temperatures dependent on materials used.
• Material Specifications: Guidance on materials for wetted parts and case materials, typically stainless steel, brass, or phosphor bronze.

Applications of EN 837-1 Compliant Instruments

Pressure gauges compliant with the EN 837-1 standard are used in a wide range of sectors, including:

• Industrial Manufacturing: Monitoring pressure in compressed air systems and hydraulic circuits.
• Oil and Gas: Measuring pressures in pipelines and storage tanks.
• Pharmaceuticals: Ensuring sterile conditions in process lines by monitoring pressure.
• Power Generation: Pressure measurements in steam systems and cooling circuits.
