Fenwal Electromechanical Controllers
Series 30000 and 30003require no external power and provide simple, rugged
and dependable temperature control. They are well proven in a
wide range of applications. Operating on either the principal
of differential expansion of metals , these controllers are available
as non-indicating surface mount designs.
OurTHERMOSWITCH® controllers operate
on the principal of differential expansion of metals providing
fast response and extreme sensitivity for precise control. With
surface mount designs the stainless steel outer case of the controller
expands at a greater rate than that of the internal bridge assembly
allowing temperature changes to be sensed instantaneously.
