What is BS EN IEC 62828‑4 about?
BS EN IEC 62828‑4 is part four of the multi-series standard that establishes specific procedures for testing level transmitters used in measuring and control systems for industrial process and machinery control systems. For general test procedures, reference is to be made to IEC 62828-1:2017, applicable to all types of transmitters.
Throughout BS EN IEC 62828‑4, the term "industrial transmitters" covers all types of transmitters used in measuring and control systems for industrial processes and for machinery.
The requirements of BS EN IEC 62828‑4 are applicable to all level measurement principles.
Detailed description of transmitters is given for two main principles for improved clarity.
BS EN IEC 62828‑4 helps you as it reviews, completes and reorganizes the existing IEC standards and create a more suitable, effective and comprehensive standard series that provides, in a systematic way, all the needed specifications and tests for the different transmitters.
Who is BS EN IEC 62828‑4 for?
BS EN IEC 62828‑4 on specific procedures for level transmitters is useful for:
- Level transmitters manufacturers
- Industries using transmitters
- Designers and testers of level transmitters
Why should you use BS EN IEC 62828‑4?
Most of the current IEC standards on industrial measurement transmitters are rather old and were developed having in mind devices based on analogue technologies. Today’s digital industrial and process measurement transmitters are quite different from those analogue transmitters: they include more functions and newer interfaces, both towards the computing section (mostly digital) and towards the measuring section (mostly mechanical). Even if some standards dealing with digital transmitters already exist, they are not sufficient, since some aspects of the performance are not covered by appropriate test methods.

BS EN IEC 62828‑4 provides definitions for different types of level transmitters.
BS EN IEC 62828‑4 explains the principles of level measurement and indicates its different applications, highlighting the aspects that may influence the test procedures.
BS EN IEC 62828‑4 defines all the parameters that have to be considered as influence quantities for the operating conditions. The test conditions in BS EN IEC 62828‑4 determine the impact of the influence quantities on the performance of the level transmitter and to verify the mechanical and the electrical conditions that a level transmitter can withstand and still work within its specifications.
BS EN IEC 62828‑4 on level transmitters covers the following main aspects:
- Hardware and software aspects
- Interfaces (to the process, to the operator, to the other measurement and control devices)
- Physical, mechanical and electrical requirements and relevant tests; clear definition of the test categories: type tests, acceptance tests and routine tests
- Performances (their specification, tests and verification)
- Environmental protection, hazardous areas application, functional safety, etc
- Structure of the technical documentation
What’s changed since the last update?
BS EN IEC 62828‑4 supersedes BS EN 60770‑1:2011, BS EN 60770‑2:2010 and BS EN 60770‑3:2014, which will be withdrawn.
