A pair of electrical contacts is mounted on the strut assembly and installed in the shell under tension or compression. Because each end of the strut assembly is mechanically connected to the ends of the shell, a net change in force is produced on the low expansion strut assembly as the high expanding shell expands or contacts with changing temperature. The temperature at which the contacts make or break can be regulated. The range of these thermostats is available from 0 to 300°C with an accuracy of plus/minus 0.1 degree.
