Fibre optic sensors - Part 1: Generic specification

IEC 61757-1:2012 is a generic specification covering optical fibres, components and sub-assemblies as they pertain specifically to fibre optic sensing applications. It has been designed to be used as a common working and discussion tool by the vendor of components and subassemblies intended to be integrated in fibre optic sensors, as well as by designers, manufacturers and users of fibre optic sensors independent of any application or installation. The objective of this generic specification is to define, classify and provide the framework for specifying fibre optic sensors, and their specific components and subassemblies. The requirements of this standard apply to all related sectional, family, and detail specifications. Sectional specifications will contain requirements specific to sensors for particular quantities subject to measurement. Within each sectional specification, family and detail specifications contain requirements for a particular style or variant of a fibre optic sensor of that sectional specification. This edition includes a substantial technical update of all clauses, definitions, and cited references with respect to the previous edition.

Capteurs a fibres optiques - Partie 1: Spécification générique

La CEI 61757-1:2012 est une spécification générique qui traite des fibres optiques, des composants et des sous-ensembles intervenant de manière spécifique dans des applications de capteurs à fibres optiques. Elle a été conçue pour être utilisée comme un outil de travail et un support de discussion par les vendeurs de composants et de sous-ensembles destinés à être intégrés à des capteurs à fibres optiques, ainsi que par les concepteurs, les fabricants et les utilisateurs de capteurs à fibre optiques indépendants de toute application ou installation. La présente spécification générique a pour objectif de définir, de classer et de fournir un cadre de travail pour la spécification des capteurs à fibres optiques, de leurs composants et de leurs sous-ensembles. Les exigences de la présente Norme s'appliquent à toutes les spécifications particulières, les spécifications de famille et les spécifications intermédiaires associées. Les spécifications intermédiaires contiendront des exigences spécifiques aux capteurs pour des grandeurs particulières à mesurer. Chaque spécification intermédiaire, chaque spécification de famille et chaque spécification particulière contient des exigences pour un modèle ou une variante particulier d'un capteur à fibres optiques de cette spécification intermédiaire. La présente édition contient une mise à jour technique significative de tous les articles, toutes les définitions et toutes les références citées par rapport à l'édition précédente.

Optična zaznavala - 1. del: Rodovna specifikacija (IEC 61757-1:2012)

Ta del standarda IEC 61757 je rodovna specifikacija, ki zajema optična vlakna, sestavne dele in sklope, ki se nanašajo posebno na zaznavo v zvezi z optičnimi vlakni. Pripravljen je bil kot skupno orodje za delo in razpravo, ki bi ga uporabljali prodajalci sestavnih delov in sklopov, ki so namenjeni za vključitev v optične senzorje, ter projektanti, proizvajalci in uporabniki optičnih senzorjev ne glede na uporabo ali namestitev. Cilj te rodovne specifikacije je opredeliti, razvrstiti in zagotoviti okvir za specifikacijo optičnih senzorjev ter njihovih posebnih sestavnih delov in sklopov. Zahteve iz tega standarda se uporabljajo za vse povezane področne, skupinske in podrobne specifikacije. Področne specifikacije bodo vključevale zahteve glede senzorjev za določene količine, ki so predmet meritve. Skupinske in podrobne specifikacije v okviru vsake področne specifikacije vključujejo zahteve za določen tip ali različico optičnega senzorja iz te področne specifikacije. Optični senzor zajema optični element za zaznavanje ali element za zaznavanje z optičnimi vlakni, v katerem se informacije ustvarijo z reakcijo svetlobe na meritev. Element za zaznavanje je lahko samo vlakno ali optični element, ki se nahaja ob optični poti. V optičnem senzorju se en ali več svetlobnih parametrov neposredno ali posredno spremeni z meritvijo nekje na optični poti, kar se razlikuje od optične podatkovne povezave, kjer se informacije le prenesejo od oddajnika do sprejemnika. Za navedene lastnosti so opredeljeni splošni preskusi ali merilne metode. Kadar je to mogoče, se te definicije sklicujejo na standard IEC, sicer je preskusna ali merilna metoda opisana v ustrezni področni, skupinski in/ali podrobni specifikaciji. V Prilogi A so za boljši prikaz klasifikacijske sheme navedeni primeri optičnih senzorjev. Navedeni primeri so namenjeni le pregledu in niso izčrpni, pri čemer ne pomenijo priporočila ali odobritve posameznega transdukcijskega načela.
