IEC 61326-2-3 Testing — Transducers with Signal Conditioning

Compatible Electronics is NVLAP-accredited for EN 61326-2-3 (2013) and IEC 61326-2-3 (2006) — the specific EMC requirements for transducers with integrated or remote signal conditioning at all three Southern California locations.

What is IEC 61326-2-3?

IEC 61326-2-3 is Part 2-3 of the IEC 61326 standard family — the specific EMC requirements for transducers with integrated or remote signal conditioning. A transducer in this context is a device that converts a physical quantity (temperature, pressure, flow, force, displacement, etc.) into an electrical signal. When the transducer includes active signal conditioning electronics — amplifiers, A/D converters, transmitters — it falls within the scope of IEC 61326-2-3.

This standard supplements the general requirements of IEC 61326-1 with test configurations and performance criteria appropriate for transducers, recognising that transducer outputs are small analogue signals easily corrupted by electromagnetic interference. The standard specifies how the transducer should be connected during immunity testing, what performance criteria apply, and how accuracy degradation during tests is to be assessed. See our IEC 61326-2 Lab Equipment Testing page for the full sub-standard family.

🔎 IEC 61326-2-3 performance criteria: Unlike general measurement equipment where performance criteria A/B/C apply, transducer performance is assessed by accuracy degradation during immunity tests. The standard defines acceptable limits for measurement error during each disturbance — for example, the output shift during a conducted RF immunity test must not exceed a defined percentage of full-scale output. Our EMC Design Consulting team can advise on how to define appropriate performance criteria for your transducer.

IEC 61326-2-3 in a Complete CE Marking Program

✓

IEC 61326-1 General Requirements

The general EMC standard for all measurement equipment. IEC 61326-2-3 supplements — not replaces — IEC 61326-1. Both apply for CE marking of transducers with signal conditioning.

✓

IEC 61326-2 Family

Part 2-3 is one of three particular requirements sub-standards in the IEC 61326-2 family alongside -2-1 (unprotected applications) and -2-2 (portable LV distribution equipment).

✓

EN 61000-6-2 Industrial Immunity

Industrial transducers installed in factory environments are often subject to industrial immunity levels. IEC 61326-2-3 specifies performance criteria for transducers at those levels.

✓

CE Marking under EU EMC Directive

EN 61326-2-3 is harmonised under EU EMC Directive 2014/30/EU. Test results using the EN version form the basis of the Declaration of Conformity for CE marking.
