Introduction to EN 837-1 Standard
The EN 837-1 standard establishes specifications for Bourdon tube pressure gauges. It provides guidelines on the design, manufacture, testing, and calibration of these instruments, ensuring consistent performance across applications.
Scope and Applicability
EN 837-1 applies to Bourdon tube pressure gauges with circular, spiral, or coiled tubes intended for measuring pressures from -0.6 bar to 1,600 bar. The standard caters to various sectors including energy, manufacturing, and environmental monitoring.
Key Parameters Defined in EN 837-1
Pressure Range
The standard specifies a pressure range from -0.6 bar to 1,600 bar, accommodating both vacuum and high-pressure applications.
Accuracy Classes
EN 837-1 defines accuracy classes as 0.1, 0.25, 0.6, 1.0, 1.6, and 2.5, each reflecting a percentage of the full-scale reading. These classes guarantee precision levels suitable for various industrial needs.
Temperature Limits
Operating temperature ranges are specified between -40°C and +200°C, while storage temperatures range from -50°C to +60°C.
Design and Construction Requirements
The standard mandates the use of corrosion-resistant materials for wetted parts and provides guidelines on the dimensions and marking of pressure gauges, ensuring durability and traceability.
Performance Specifications
Performance criteria include response time and stability. The standard ensures gauges can respond within a specific time frame, typically less than 2 seconds, and remain stable in fluctuating conditions.
Testing and Calibration
EN 837-1 specifies tests for leakage, overpressure, and pressure cycling. Calibration procedures are provided to maintain accuracy, with recalibrations advised annually or after 5,000 operational hours.
