CENELEC - EN IEC 62828-1

Reference conditions and procedures for testing industrial and process measurement transmitters - Part 1: General procedures for all types of transmitters

active, Most Current
Organization: CENELEC
Publication Date: 1 February 2018
Status: active
Page Count: 92
ICS Code (Industrial process measurement and control): 25.040.40
ICS Code (Metrology and measurement in general): 17.020
scope:

This Part of IEC 62828 establishes a general framework for defining reference conditions and test procedures applicable to all types of industrial and process measurement transmitters (PMTs) used in measuring and control systems for industrial process and machinery. These reference test conditions are divided into "standard reference conditions", which apply when determining the accuracy of measurement, and "ambient and process reference conditions", which are used to assess the influence of external quantities on the measurement.

For the purpose of this document, an analogue PMT is a process measurement transmitter with an analogue current or voltage output, irrespective of the technology adopted and the complexity of the circuitry. All the other process measurement transmitters, with digital output only or with hybrid analogue and digital output (e.g. HART®), are considered to be digital PMTs.

For general test procedures, reference is made to IEC 62828-1, which is applicable to all types of industrial and process measurement transmitters.

Additional specific test procedures for given types of PMTs (pressure, temperature, level, flow) are covered by other parts of this series.

NOTE 1 In industrial and process applications, to indicate the process measurement transmitters it is common also to use the terms "industrial transmitters", or "process transmitters".

NOTE 2 For better clarity, when the complete definition "industrial and process measurement transmitter" makes the sentence too long in this document, the short term "transmitter" is used instead.

Proximity devices with analogue output are excluded from the scope of this document.
