A cooktop appliance comprising:
- a panel comprising a top surface and a bottom surface;
- a burner disposed on the panel;
- a terminal block positioned on the panel adjacent to the burner;
- a griddle plate configured to be supported over the burner;
- and
- a hermetically sealed temperature sensor embedded in the griddle plate, the temperature sensor comprising a base, a probe extending from the base, a first contact pad in the base, a second contact pad in the base, and a hermetic seal formed in the base, wherein the contact pad is configured to form an electrical connection with the terminal block, wherein the hermetic seal comprises a ceramic-to-metal seal between an electrical contact of the contact pad and a ceramic insert, and a ceramic-to-metal seal between the ceramic insert and a metal portion of the base, wherein the first contact pad and the second contact pad are configured to collectively form an electrical connection with the terminal block, and wherein the hermetic seal formed in the base comprises a hermetic seal between each of the first contact pad and the second contact pad and the base.
