25、itioning 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 standardizati
26、on 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 en
27、trusted 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 Inte
28、rnational 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
29、 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 o
30、f 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
31、 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 de
32、clared 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 Natio
33、nal 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
34、 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
35、 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
36、 and constitutes a technical revision. SANS 61326-2-3:2009This s tandard may only be used and printed by approved subscription and freemailing clients of the SABS .61326-2-3 IEC:2006 9 The text of this standard is based on the following documents: FDIS Report on voting 65A/477/FDIS 65A/484/RVDFull i
37、nformation 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 IEC 61326 is to be used in conjunction with IEC 61326-1 and follows the same
38、 numbering of clauses, subclauses, tables and figures as that standard. 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 ada
39、pted accordingly. NOTE The following numbering system is used: subclauses, tables and figures that are numbered starting from 101 are additional to those in Part 1; unless notes are in a new subclause or involve notes in part 1, they are numbered starting from 101 including those in a replaced claus
40、e 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 has decided t
41、hat the contents of this publication will remain unchanged until the maintenance result 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, or am
42、ended.

43、l conditions and performance criteria for transducers with integrated or remote signal conditioning 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 integra
44、ted 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
45、 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 10
46、2): 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 elect
47、rical 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.; tran
48、sducer 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 corre
49、sponding test levels of IEC 61326-1. Additional requirements and exceptions for specific types of transducers are given in the annexes to this standard.
