Reference conditions and procedures for testing industrial and process measurement transmitters - Part 2: Specific procedures for pressure transmitters

IEC 62828-2:2017 establishes specific procedures for testing pressure process measurement transmitters (PMT) used in measuring and control systems for industrial processes and for machinery control systems. A pressure PMT can feature a remote seal to bring the process variable to the sensing element in the PMT. When the remote seal cannot be separated from the PMT, the complete device is tested.

Conditions de référence et procédures pour l’essai des transmetteurs de mesure industrielle et de processus - Partie 2: Procédures spécifiques pour les transmetteurs de pression

L'IEC 62828-2:2017 établit les procédures spécifiques d’essai des transmetteurs de mesure de processus (PMT – process measurement transmitter) de pression utilisés dans les systèmes de mesure et de commande des processus industriels et des systèmes de commande des machines. Un PMT de pression peut être équipé d’un joint distant pour amener la variable de processus à l’élément de détection dans le PMT. Si le joint distant ne peut pas être séparé du PMT, l’appareil complet est soumis à l’essai.

Referenčni pogoji in postopki za preskušanje industrijskih in procesnih merilnih oddajnikov - 2. del: Posebni postopki za dajalnike tlaka (IEC 62828-2:2017)

Ta del standarda IEC 62828 določa specifične postopke za preskušanje tlačnih procesnih merilnih oddajnikov (PMT), uporabljenih v merilnih in kontrolnih sistemih za industrijske procese in sisteme za upravljanje strojev.
Tlačni procesni merilni oddajnik je lahko opremljen z ločenim tesnilom, ki posreduje procesno spremenljivko merilnemu elementu v procesnem merilnem oddajniku. Kadar ločenega tesnila ni mogoče odstraniti s procesnega merilnega oddajnika, se preskusi celotno napravo.
Za splošne preskusne postopke je omenjen standard IEC 62828-1, ki se uporablja za vse vrste procesnih merilnih oddajnikov.
OPOMBA: V industrijskih in procesnih uporabah so procesni merilni oddajniki pogosto poimenovani tudi »industrijski oddajniki« ali »procesni oddajniki«.

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 Nat
