Mechanical behavior of carbon ceramic TVO temperature sensors

This paper presents the results of investigations on some carbon ceramic TVO resistance temperature sensors during thermal cycling and hydrostatic pressure tests. In addition to already performed cycling tests with moderate temperature changes, now very harsh cycling conditions with temperature changes up to 40 K/s were applied to find out the mechanical stability of the design of such sensors. Furthermore, some tests with hydrostatic pressure were done in order to get additional information of the sensor characteristic. For better understanding of the construction of these sensors one of them was cut and prepared for demonstration of the areas where mechanical forces appears.
