Synopses & Reviews
The concept of traceability has evolved to ensure measurements can be communicated consistently and unambiguously. This new edition of a classic reference offers a systematic treatment of traceable temperature measurement and presents a practical guide to the principles and purpose of measurements. With an emphasis on recognizing sources of uncertainty, Nicholas and White examine the most commonly used thermometers: liquid-in-glass thermometers, platinum resistance thermometers, thermocouples and radiation thermometers.
The new edition features:
* How to make measurements fit for purpose; the importance of traceability, uncertainty and measurement standards.
* The latest advances in industrial and laboratory thermometry, with a unique emphasis on practical advice on how to recognise and treat errors.
* An updated chapter on calibration, reflecting the changes brought about by the release of the ISO 17025 standard for laboratory accreditation.
* A systematic treatment of uncertainty in measurement consistent with ISO guidelines, including numerous thermometry examples and exercises.
Practising engineers, scientists and technicians will value the authors' emphasis on practical advice combined with quality concepts. Engineering students, researchers and instrument manufacturers will benefit from the self-teaching approach.
Synopsis
The accurate measurement of temperature is a vital parameter in many fields. A critically important aspect of applying any temperature sensor is that of traceable calibration - a concept that has been developed to ensure that all measurements made are accurate and legally valid.
This timely new edition reflects the marked move towards ISO accreditation in measurement laboratories internationally, and the ever increasing emphasis on adequate uncertainty analysis for measurements in accredited laboratories to conform to national and international bodies, and the SI and Metric treaty.
* Fully revised and updated to incorporate the latest trends and developments in measurements and calibration
* Provides information concurrent with the latest ISO Quality Standards for assessing the uncertainty of measurement sensors
* Offers detailed converage of traceability, how to make traceable measurements and how to design, carry out and report calibration
* Unique emphasis on possible problems in the field, and provision of practical advice on how to recognise and treat errors.
An essential reference resource for practising and training engineers, scientists and technicians in accredited test and calibration laboratories involved in temperature measurement and calibration.
Synopsis
Diese 2. komplett berarbeitete und aktualisierte Neuauflage des Handbuchs ber cksichtigt alle wesentlichen Entwicklungen auf den Gebieten der Temperaturmessung und der Eichung der dazu erforderlichen Ger te. Besprochen werden u.a. die aktuellen ISO-Standards zur Genauigkeit von Messsensoren. Der Leser lernt, reproduzierbare Messungen auszuf hren sowie Eichungen zu entwerfen, durchzuf hren und zu protokollieren. Im Unterschied zu vergleichbaren Werken wird hier auch auf Fehlerquellen, Fehlererkennung und -beseitigung eingegangen.
