Welcome to NOTED

“Novel Techniques for Traceable Temperature Dissemination” (NOTED) is a Joint Research Project focused on the development of new advanced techniques for providing improved traceability to the kelvin to support its wider and simpler dissemination to users.

This project will provide solutions to the most pressing problems associated with high level practical temperature metrology, in the most widely used temperature range, from -218 ºC up to 1000 ºC.

NOTED is an EMRP funded Joint Research Project coordinated by Centro Español de Metrología.

The Project

“Novel Tecniques for Traceable Temperature Dissemination” (NOTED) is an EMRP funded Joint Research Project coordinated by Centro Español de Metrología.

Background

The Mise en Pratique for the definition of the kelvin (MeP-K) was created in 2006 by the Consultative Committee for Thermometry (CCT) to give definitive guidance for the practical realisation of the unit in accordance with the International System of Units (SI). The MeP-K opens a new and flexible means of updating and expanding the range of recognised thermometry methods beyond those currently in use. In addition future versions of the MeP-K will include; the redefinition of the kelvin in terms of the Boltzmann constant, the realisation (and where possible dissemination) of the kelvin by primary methods and by indirect approximations capable of exceptionally low uncertainties or increased reliability. The expected outcome is greater flexibility in traceable temperature measurement.

The International Temperature Scale of 1990 (ITS-90) is the current temperature scale, internationally agreed, in use throughout the world. It is the tool to perform practical measurement of temperature within the temperature range covered by the project, in accord with the International System of Units (SI). After the redefinition of the kelvin in terms of the Boltzmann constant the ITS-90 will continue in use because it is a robust and reliable tool, but it has some limitations and some pending questions that need to be solved; a number of the most pressing of these are addressed in this JRP. This JRP aims to answer the needs and solve the weaknesses of the present established methods for the dissemination of temperature and, in addition, prepare the thermal metrology community for the forthcoming redefinition of the temperature unit.

Objectives

This JRP is focused on the development of new advanced techniques for providing improved traceability to the kelvin to support its wider and simpler dissemination to users. It will also enable EURAMET members become the world leaders in the practical dissemination of the kelvin.

The JRP aim will be achieved by:

  1. The development of new interpolation instruments and techniques and through implementing practical primary thermometers (able to provide traceability directly to the thermodynamic temperature not the defined scale, the International Temperature Scale of 1990 (ITS-90) as currently ), which will be able to perform a calibration of Standard Platinum Resistance Thermometers (SPRT) directly to the new kelvin definition.
  2. Addressing current issues related to the ITS-90 temperature fixed points to resolve the discrepancies in their realisation leading to a reduction of the uncertainty of the fixed points. 

Impact

This JRP aims to solve some of the pressing weaknesses of the ITS-90 (T90) and will help establish a practical link between the thermodynamic temperature T and T90. This JRP will provide solutions to the most pressing problems associated with high level practical temperature metrology, in the most widely used temperature range, from -218 ºC up to 1000 ºC. Temperature is one of the most frequently measured physical quantities in science and industry for example in the pharmaceutical, semiconductors, petrochemical or food processing industries.

National Metrology Institutes (NMIs) will benefit from the results of this project because of its direct and significant contribution to developing the MeP-K and users in science and industry will benefit from improved practicality of the MeP-K e.g.:

Work Packages

The works of the project “Novel Techniques for Traceable Temperature Dissemination” (NOTED) are structured into five technical workpackages (WP) plus one dedicated to impact and another to management. In brief the main objectives of the technical work packages are:

  • Work package 1

    Reducing the uncertainties related to the realisations of the defining fixed points.

    Improvement of the present realization of the ITS-90 by a systematic study of the two most important sources of uncertainty in the realization of the defining fixed points: the thermal fluxes and the impurities concentration. This will involve experiments, and modelling based on fundamental physics.

  • Work package 2

    SPRT and CSPRT calibration procedures and temperature scale non-uniqueness.
     

    New procedures to calibrate SPRTs and capsule type SPRTs will be developed and new data on the oxidation, contamination and self-heating effects for the latest SPRT models will be obtained. In addition optimized procedures for SPRT annealing and handling will be developed.

  • Work package 3

    New temperature fixed points for improved dissemination of ITS-90 and future International Temperature Scales.

    Step change improvement of the most promising new fixed points, to yield measurement uncertainties sufficiently low to enable meaningful improvement of the present temperature scale. Development of brand-new fixed points to fill the large temperature gaps that exist between some established defining fixed points.

  • Work package 6

    Creating Impact.

                  

    The aim of this work package is to ensure that the results achieved by the project are adequately and appropriately communicated to the stakeholders and end-user community and that input and feedback is obtained from this community. The stakeholders of this JRP are essentially the CCT of the BIPM, the National Metrology Institutes both within and outside Europe, the National Accreditation Bodies and their Accredited Laboratories and the manufacturers of instrumentation used in the temperature measurements (from the highest to the lowest end).

  • Work package 7

    Management and coordination.
     

    The aim of this work package is to ensure effective management of the project, timely reporting on the scientific activities and budget control. Management and reporting of the JRP will be in accordance with EMRP guidelines.
    The management of the project is crucial and therefore a significant resource has been allocated to this work package. The appointment of key scientists as work package leaders gives the project a strong scientific value, a coherent structure and will facilitate the overall coordination of the project.

The Project Consortium

This Consortium brings together a wide range of European National Metrology Institutes (NMIs) with expertise in the field of thermal metrology.

Some of these NMIs, with a comprehensive capacity for cutting-edge research in thermometry, will carry out some of the most innovative developments in the field (e.g. brand-new fixed points, new equipment for practical thermodynamic temperature calibrations, near infrared radiation thermometers, etc.). These works will be complemented by other NMIs which will focus in specific contributions to different tasks in which they have proven expertise (e.g. thermocouple thermometry, calibration of standard platinum resistance thermometers or study of the uncertainties in the realization of the temperature fixed points).
