The deviation of the device's actual output from a theoretical straight-line relationship with its input.
The range through which an input can vary without initiating a change in the output.
Kept within a stable range to prevent moisture interference.
This helps control loop designers select appropriate devices for fast processes. iec 612982
To fully implement Part 2, it is often used alongside other parts of the series:
, insulation strength, and power consumption (both electrical and pneumatic). Drift Analysis : Provides guidelines to quantify start-up drift long-term drift
If you meant a (e.g., -1, -3, -4) or a completely different standard (like IEC 61282 for fiber optics or IEC 61298-2 for devices), please clarify, and I can provide a more focused paper or abstract. The deviation of the device's actual output from
Process measurement and control devices – General methods and procedures for evaluating performance – Part 2: Tests under reference conditions.
The standard applies to a wide range of industrial equipment, including but not limited to: Pressure sensors and transmitters. Flow meters and sensors. Temperature measurement devices. Level sensors. Process controllers.
In the world of industrial automation, accuracy and reliability are paramount. Whether it is a pressure transmitter in a chemical plant or a flow meter in a water treatment facility, the instruments measuring and controlling processes must operate within strict performance parameters. The serves as a foundational international guideline for evaluating these crucial performance characteristics. This helps control loop designers select appropriate devices
If you actually meant a different number (e.g., 61298-2, or another standard like 61260 or 61290), please clarify.
It allows engineers to compare different devices from different vendors on an equal footing based on data gathered under the same reference conditions.
Measuring the stability of DC output signals. 4. Drift Measurements Long-term reliability is assessed through:
