Electrical equipment for measurement, control and laboratory use - EMC requirements -- Part 2-3: Particular requirements - Test configuration, operational conditions and performance criteria for transducers with integrated or remote signal conditioning
In addition to the requirements of IEC 61326-1, this part of IEC 61326 specifies more detailed test configurations, operational conditions and performance criteria for transducers with integrated or remote signal conditioning. This standard applies only to transducers characterized by their ability to transform, with the aid of an auxiliary energy source, a non-electric quantity to a process-relevant electrical signal, and to output the signal at one or more ports. This standard includes transducers for electrochemical and biological measured quantities. The transducers covered by this standard may be powered by a.c. or d.c. voltage and/or by battery or with internal power supply. Transducers referred to by this standard comprise at least the following items (see Figures 101 and 102): - one or more elements for transforming a non-electrical input quantity to an electrical quantity; - a transmission link for transferral of the electrical quantity to a component for signal conditioning; - a unit for signal conditioning that converts the electrical quantity to a process-relevant electrical signal; - an enclosure for enclosing the above-stated components fully or in parts. Transducers referred to by this standard may also have the following items (see Figures 101 and 102): - a communication and control unit; - a display unit; - control elements such as keys, buttons, switches, etc.; - transducer output signals (for example, switch outputs, alarm outputs) which are clearly assigned to the input signal(s); - transducers with signal conditioning which may be integrated or remote. The manufacturer specifies the environment for which the product is intended to be used and utilizes the corresponding test levels of IEC 61326-1. Additional requirements and exceptions for specific types of transducers are given in the annexes to this standard.

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with an IEC Publication.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
This International Standard IEC 61326-2-3 has been prepared by subcommittee 65A: System
aspects, of IEC technical committee 65: Industrial-process measurement and control.
The IEC 61326 series cancels and replaces IEC 61326:2002 and constitutes a technical
revision.

When a particular subclause of Part 1 is not mentioned in this part, that subclause applies as
far as is reasonable. When this standard states “addition”, “modification” or “replacement”, the
relevant text in Part 1 is to be adapted accordingly.

1 Scope
In addition to the requirements of IEC 61326-1, this part of IEC 61326 specifies more detailed
test configurations, operational conditions and performance criteria for transducers with
integrated or remote signal conditioning.
This standard applies only to transducers characterized by their ability to transform, with the
aid of an auxiliary energy source, a non-electric quantity to a process-relevant electrical
signal, and to output the signal at one or more ports. This standard includes transducers for
electrochemical and biological measured quantities.
The transducers covered by this standard may be powered by a.c. or d.c. voltage and/or by
battery or with internal power supply.
Transducers referred to by this standard comprise at least the following items (see Figures 101
and 102):
– one or more elements for transforming a non-electrical input quantity to an electrical
quantity;
– a transmission link for transferral of the electrical quantity to a component for signal
conditioning;
– a unit for signal conditioning that converts the electrical quantity to a process-relevant
electrical signal;
– an enclosure for enclosing the above-stated components fully or in parts.
Transducers referred to by this standard may also have the following items (see Figures 101
and 102):
– a communication and control unit;
– a display unit;
– control elements such as keys, buttons, switches, etc.;
– transducer output signals (for example, switch outputs, alarm outputs) which are clearly
assigned to the input signal(s);
– transducers with signal conditioning which may be integrated or remote.
The manufacturer specifies the environment for which the product is intended to be used and
utilizes the corresponding test levels of IEC 61326-1.
Additional requirements and exceptions for specific types of transducers are given in the
annexes to this standard.

Addition:
A system for monitoring the behaviour of the EUT and for registering the output values shall

The measurement uncertainty and the bandwidth of the monitoring system shall be adapted to
the characteristics of the transducer.
Transmission links are considered as separate input and output lines.
The tests shall be conducted in compliance with the environmental conditions for the
transducer specified by the manufacturer and using the specified supply voltage.
In the case of battery-operated transducers that can also be used when connected with a
power supply, both operating modes (stand-alone and externally supplied) shall be tested.
In cases in which the manufacturer's installation instructions stipulate the use of external

ranges are known to provide worst-case immunity results within normal application.
Only operational functions compliant with the specified use under the nominal conditions are
permitted. Defined functions that cannot be set under electromagnetic compatibility test
conditions shall be simulated by appropriate measures. This shall be done in such a way that
the electromagnetic compatibility behaviour of the transducer is not affected.
