During the period from 1920 to 1960 there was a fundamental change in the c
21、omprehension and usage of physical quantities, which was particularly promoted by the works of Julius Wallot published between 1922 and 1953. In this process the various systems of physical units and the usage of numerical equations were replaced by the SI-units (see ISO 1000) and the usage of quant
22、ity equations. So the quantities were no longer linked to certain units. This development culminated in the publishing of the first edition of the German standard DIN 1313 Notation of physical equations in sciences and technology in 1931 and the resolutions of the tenth general conference of weights
23、 and measures in 1954. Since then it has been considered incorrect to address a quantity by its unit. In view of this, measuring instruments should not be addressed by the unit of the measured quantity but only by the measured quantity or the measuring task itself. Referring to the question of marke
24、t relevance, it must be stated, that especially with respect to the international project of standardized classification and documentation in multilingual equipment descriptions, it is important to critically address the situation regarding the designation of measuring instruments. Ideally, every ma
25、nufacturer should use the same terminology. In practice, there is confusion in the proper designation of measuring instruments within catalogues and sales brochures which also has consequences in technical literature. It is not the intention of this standard to enforce particular usages in any langu
26、age but to make recommendations that remove the linguistic confusion in this field or at least, reduce it. Considering the urgent necessity of unambiguous technical communication over language boundaries, this is a legitimate goal. This could also be considered to be a matter of global importance. B
27、S EN 62419:2009 6 62419 IEC:2008(E) CONTROL TECHNOLOGY RULES FOR THE DESIGNATION OF MEASURING INSTRUMENTS 1 Scope and object This International Standard is applicable to measurement technology. It defines rules for the unambiguous designation of different types of measuring instruments and of measur
28、ing instrument features with the intention of enabling unambiguous technical communication over language boundaries. The scope of this International Standard is the adaptation of the designation of measuring instruments and of measuring instrument features to the state of science by designating them
29、 according to the measuring quantity or the measuring task instead of the unit, and the adaptation of the designation of measuring instruments and of measuring instrument features to the terms given in the ISO/IEC Guide 99 (VIM). It is strongly recommended that “ measuring instrument” is used as sec
30、ondary component in compound terms. This is consistent with the objective of standardization, namely uniformity, especially since the meaning of other secondary components, e.g. “indicator”, “gauge”, “meter”, is no more descriptive than that of the standard component in this context. For exceptions
31、see 4.1 and A.2. The ambiguous secondary component “. sensor” shall not be used. In its place one of the secondary components “ sensing element”, “. detector”, “. transformer”, “. transducer”, “ transmitter”, “. measuring instrument” or “. measuring chain” shall be used, depending on the task of the
32、 functional unit being termed. The definitions for detector (detecting device), transformer, transducer and transmitter are given in IEC 60050-351. 2 Normative references The following referenced documents are indispensable for the application of this document.

In compound expressions, the term “measuring instrument” should only be used to signify a displaying measuring inst

NOTE 2 The output measured value can refer directly to the measured quantity, or it can be derived from this using a processing method. The pro
40、cessing method can be invariable, manually adjustable or programmable. NOTE 3 Linguistic usage is not unambiguous. In IEC 60050-311 displaying measuring instruments are also termed “indicating (measuring) instruments”. In ISO/IEC Guide 99, displaying measuring instrument and indicating measuring ins
