28、ion, operational conditions and performance criteria for transducers with integrated or remote signal conditioning FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC National Committ
29、ees). 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 Availabl
30、e 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 organ
31、izations 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 m
32、atters 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 Nati
33、onal 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,
34、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 its
35、elf does not provide any attestation of conformity. Independent certification bodies provide conformity assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any services carried out by independent certification bodies. 6) All users should ensure that
36、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 natur
37、e 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
38、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 Interna
39、tional Standard IEC 61326-2-3 has been prepared by subcommittee 65A: System aspects, of IEC technical committee 65: Industrial-process measurement, control and automation. This second edition cancels and replaces the first edition published in 2006. This edition constitutes a technical revision. Thi
40、s edition includes the following significant technical change with respect to the previous edition: update of the document with respect to IEC 61326-1:2012. 61326-2-3 IEC:2012 5 The text of this standard is based on the following documents: FDIS Report on voting 65A/629/FDIS 65A/638/RVD Full informa
41、tion on the voting for the approval of this standard can be found in the report on voting indicated in the above table. This publication has been drafted in accordance with the ISO/IEC Directives, Part 2. This part of the IEC 61326 series is to be used in conjunction with IEC 61326-1:2012 and follow
42、s the same numbering of clauses, subclauses, tables and figures. When a particular subclause of IEC 61326-1 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 IEC 61326-1 is to be
43、adapted accordingly. NOTE The following numbering system is used: subclauses, tables and figures that are numbered starting from 101 are additional to those in IEC 61326-1; unless notes are in a new subclause or involve notes in IEC 61326-1, they are numbered starting from 101 including those in a r
44、eplaced clause or subclause; additional annexes are lettered AA, BB, etc. A list of all parts of the IEC 61326 series, under the general title Electrical equipment for measurement, control and laboratory use, control and laboratory use EMC requirements, can be found on the IEC website. The committee
45、 has decided that the contents of this publication will remain unchanged until the stability date indicated on the IEC web site under “http:/webstore.iec.ch“ in the data related to the specific publication. At this date, the publication will be reconfirmed, withdrawn, replaced by a revised edition,
46、or amended. 6 61326-2-3 IEC:2012 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 1 Scope In addition t
47、o the requirements of IEC 61326-1, this part 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
48、 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. o
49、r 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
