Abstract
To reduce uncertainty of calibrations of contact thermometers using dry block calibrators a concept was developed at Institute for Process Measurement and Sensor Technology of Technische Universität Ilmenau This concept uses a multizone heating heat flux sensors and a multiple fixedpoint cell The paper shows the concept and its validation on the basis of a dry block calibrator with a working temperature range of 70circ hbox C to 430circ hbox C The experimental results show a stability of pm 4hbox mK for the reference temperature and axial temperature differences in the normalization block less than pm 55hbox mK
