Abstract
A temperature sensor assembly is provided. The temperature sensor includes an aluminum capillary soldered to an actuation unit. The actuation unit operably fluidly couples to the capillary to define an internal cavity storing a working fluid. The working fluid configured to manipulate the actuation unit when the working fluid changes temperature. Solder sealingly couples the capillary to the actuation unit.
Claims20
A temperature sensor assembly comprising:
- an aluminum capillary;
- an actuation unit operably fluidly coupled to the capillary, the aluminum capillary and actuation unit defining an internal cavity storing a working fluid, the working fluid configured to manipulate the actuation unit when the working fluid changes temperature;
- and
- solder sealingly coupling the capillary to the actuation unit.
