Introduction

The EN 837 standard is a comprehensive set of guidelines that address the requirements for the design, manufacturing, and testing of pressure gauges. Originating from European standards, it provides uniformity and reliability for pressure measurement instruments used across various industrial sectors.

Understanding the EN 837 Standard

The EN 837 standard comprises three parts: EN 837-1, EN 837-2, and EN 837-3. Each part pertains to different types of pressure measuring devices:

• EN 837-1: Covers Bourdon tube pressure gauges.
• EN 837-2: Deals with selection and installation recommendations for pressure gauges.
• EN 837-3: Concerns diaphragm and capsule pressure gauges.

Parameters Covered by EN 837

The EN 837 standard specifies several key parameters essential for pressure gauges:

• Accuracy Classes: Ranging from Class 0.1 to Class 4.0, indicating the precision level.
• Pressure Ranges: Typically from 0 to 1600 bar, accommodating various industrial needs.
• Temperature Limits: Operational temperatures generally span -40°C to +60°C.
• Materials: Prescribes materials for different parts such as the measuring element, case, and window.

Applications of the EN 837 Standard

The EN 837 standard finds its applications across several industries, ensuring precise pressure measurements and safety in operations. Some critical applications include:

• Oil and Gas: For monitoring and controlling pressure in pipelines and storage facilities.
• Manufacturing: Maintaining pressure in pneumatic and hydraulic systems.
• Food and Beverage: Used in processing plants for safety and quality assurance.
