Contact Thermometry - Training Course

Registration and date of the course

Price: 1850 EURO

Introduction
Do you measure temperature? Most likely! About one half of all measurements in the world are temperature measurements. Temperature impact on our basic comfort is a vital parameter in health care, crucial to management and modeling of local and global environment and almost all materials processed in industries, such as steel, petrochemicals, glass, ceramics, power generation, pharmaceuticals, foods, refrigeration, etc. This three-day course covers measurement of temperature and calibration of temperature measuring instruments. It incorporates extensive demonstrations, hands-on practical exercises and theoretical exercises. The emphasis is to ensure that you can apply the techniques and knowledge at your own workplace.

Who should attend?
The course is relevant to any personnel who use or check thermometers as part of laboratory testing, plant installation or monitoring and maintenance tasks. The course is designed to provide value for senior technicians, engineers and technical staff from a wide range of industries, calibration and testing laboratories involved in laboratory accreditation and establishing measurement traceability under an ISO quality system.  The course is suitable for participants with or without previous measuring experience. The course curriculum is applicable to both calibration and manufacturing processes.

Participants should have a basic level of mathematics: multiplication, division, uses of graphs and tables and be acquainted with GUM uncertainty analysis.

Course content
The course curriculum is based on Danish Technological Institute’s more than 100 years of experience in designing test setups, calibration in various fields, verification and as a leading partner in industrial development for Danish and international companies. Besides being the National Reference Laboratory for Contact Thermometry in Denmark since 1990, this experience includes measurement of flow, pressure, mass and force among others as well as operation of data acquisition systems.

The course covers the use, practical and theoretical aspects of temperature measurements, calibration and maintenance with emphasis on methods and guidelines for designing calibrations and measurements that you can use immediately at your workplace. The course is designed to be highly interactive to enable you to benefit from the experience of the other participants and the presenters and to enable you to emphasise the practical consequences of the ideas and techniques. There will be a number of demonstrations, hands-on exercises, theoretical examples and exercises and also opportunities to discuss specific problems.

The course will give you a clear step-by-step approach with practical examples and techniques covering the whole process from analysing system requirements, interpreting specifications and buying equipment to calibration and maintenance. The necessary concepts are based on hands-on exercises to develop the practical skills.

The course includes an exam, a certificate of participation and a certificate of the exam result.

Objectives
After the course you will have obtained:

  • An understanding of the principles of operation of common temperature sensors and their instrumentation, especially thermocouples, resistance and liquid-in-glass thermometers.
  • Experience with suitable processes for calibrating and using temperature measurement equipment.
  • An insight needed to identify various sources of error that affect temperature measurements and tips and tricks in order to recognise problems.
  • Development of practical skills through hands-on exercises

Furthermore you will have learned about:

  • Basic measurement concepts
  • Why measurements sometimes do not work
  • Measurement design
  • Making measurements traceable
  • Principles of calibration
  • Assessing the uncertainty in measurements

Why participate?
Measurements are the basis of all commercial decisions and the associated uncertainty is an assessment of the risk of making wrong decisions based on our measurements. Temperature is one of the most commonly measured parameters in the key sectors in the industry such as medicine, meteorology and technology, and in everyday life. The primary aim of this course is to provide information that enables the users to choose the right equipment and methods meeting their needs, recognise faulty thermometers and to install and use thermometers correctly. All concepts at the course are treated in a practical and pragmatic matter ensuring direct knowledge to value.
