Evaluation International are pleased to announce the establishment of a national EMPHASIS ASSESSMENT register which is being made available to Evaluation International Member companies.  This register brings together all planned, in-progress and complete Emphasis Assessments, undertaken on behalf of the Sponsor Companies. 

In addition to this Evaluation International has established a Working Group to oversee the development of the Register and supporting services. Any organisations wishing to access the register or participate in the working group should email: enquiries@evaluation-international.com and a member of our team will be happy to assist.

REPORT TITLE

K-Type Thermocouple Hysteresis – Interim Report

ABSTRACT

This report is a continuation of the work carried out to produce EI report T1962X15, in which a number of K-type thermocouples were examined to gain an understanding of drift in their measured values over a period of time. Work was later carried out to evaluate whether any hysteresis is present in the measurement of K-type thermocouples as a result of being subjected to a range of varying temperatures. The K-type thermocouple tested was Model number 408-055 manufactured by TC Ltd and using NiCr/NiAl. The functional purpose of the tests was to provide a realistic evaluation of the accuracy of K-type thermocouples which have been subjected to repeatedly varying temperature environments.
