OPERATING
PRINCIPLES
These
SR Thermostats are strut and tube type thermostats comprised of
two basic parts (1) the outer shell made of high expanding metal
and (2) the strut assembly made of low expanding metal.
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 contracts with changing
temperature. The termperature at which the contacts “make”
or “break” can be regulated. The accuracy is considerably
better than that obtainable from other types of Thermostat, such
as the snapacting type. Low load switching differentials of less
than 0.1 degree C are achieved.
