Iec 612982 ((top)) -

Implementing IEC 61298-2 offers immediate advantages across the entire automation supply chain:

The core of IEC 61298-2 revolves around a series of tests that determine essential performance metrics: 1. Accuracy and Error Measurement

Applies to all measurement and control devices with clear input/output relationships. iec 612982

A flow transmitter is tested at 23°C ± 2°C, 50% RH, with clean power. That becomes its "reference performance." If it fails in a hot, humid plant, you know it is due to environmental effects, not the device itself.

The same input values are applied multiple times consecutively from the same direction. This measures the device’s ability to reproduce identical output readings under unvarying conditions. 3. Hysteresis Evaluation That becomes its "reference performance

: Covers devices with defined input/output variables.

Understanding IEC 61298-2: The Standard for Testing Process Control Devices Under Reference Conditions with clean power.

Key tests outlined in Part 2 include:

IEC 61298-2 is designed for a broad range of industrial applications. It is applicable to any device that requires performance validation, including but not limited to: Pressure transmitters Differential pressure transmitters Flow meters Level sensors Temperature transmitters Control valves (positioners)

Verify that the device provides the same output for the same input multiple times.
