Thermoswitch® Temperature Controllers
17000 and 18000 Thermoswitch® Series
Series 17000 and 18000
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.
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.
