Fenwal Electromechanical Controllers require 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 or
of liquid expansion, these controllers are available as indicating
and non-indicating probe type, surface mount and bulb & capillary
designs.
Our THERMOSWITCH ® controllers operate
on the principal of differential expansion of metals providing
fast response and extreme sensitivity for precise control. Differential
expansion in the probe type controllers occurs between the internal
strut and the external tube. 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.
In our snap action liquid filled controllers, the expandable
liquid surrounding the bellows is in direct contact with the
temperature sensing outer shell providing a fast response for
accurate temperature sensing. These controllers are available
with a single circuit or dual circuit that can be set at any
temperature within the controller's range. On dual circuit units,
each switch may be set individually, allowing independent action.
