Manufacturers must now verify temperature influence over a broader span, including rapid thermal cycling (10°C/min, up from 2°C/min).
The error rate shall not exceed (10^-6) under any influence quantity. iec 612982 new
If you are a control systems engineer, a plant manager, or an instrumentation technician, understanding what is "new" in IEC 61298-2 is not just an academic exercise—it is a regulatory and operational necessity. This article unpacks the most critical changes, how they affect your legacy equipment, and why the 2025 update is being called the most significant overhaul in 15 years. Manufacturers must now verify temperature influence over a
Modern plants use variable frequency drives (VFDs) and switch-mode power supplies that inject harmonics and high-frequency ripple onto the 24V DC loop. The old test used a pure DC source. This article unpacks the most critical changes, how
: Evaluating how devices respond to changes over time, including dead band and response times.
IEC 61298-2:2022 is a standard that specifies requirements for the design, testing, and documentation of process automation and control devices, including sensors, actuators, and controllers. The standard covers various aspects, such as:
If your products were certified under the 2008 edition, you must transition. Here is a practical timeline.
