Abstract
Components for use in a temperature controlled heatable object are provided in which a temperature sensor is connected to a transmitter such as a Radio Frequency Identification (RFID) tag. The RFID tag is encased in a protective overmolding and connected to the temperature sensor via a mineral insulated cable. An end cap containing a potting material (such as silicone or ceramic) is placed over the temperature sensor and laser welded to a sheathing of the mineral insulated cable. A potting material for use in a heatable object is also provided comprising a silicone-based material that is modified by adding bauxite to increase thermal conductivity.
Claims20
A component for a heatable object comprising:
- a temperature sensor having an end cap of a material to increase thermal conductivity;
- a transmitter associated with said temperature sensor, said transmitter being operable to communicate temperature information obtained by said temperature sensor to a heating device;
- and
- a shell at least partially surrounding said transmitter and at least partially surrounding a portion of cabling connecting said temperature sensor to said transmitter when said transmitted is located within a handle or other cavity of the heatable object,
- wherein,
- the cabling (i) exits said transmitter in a direction parallel to a bottom surface of the heatable object, (ii) has a portion that runs in a direction perpendicular to the bottom surface of the heatable object, and (iii) has a portion that runs along the bottom surface of the heatable object such that the cabling substantially follows a contour of the heatable object.
