The BES-5 Buk (БЭС-5) reactor was a fast breeder reactor which used thermocouples based on semiconductors to convert heat directly into electricity.

The invention solved this problem by using embedded thermocouples to constantly check the temperature, and then feeding the measured values into a computer.

Thermo Electron has used thermocouples to provide power in space, taking advantage of the extreme temperature difference between the side of an object facing the sun and the part in shadow.

We attempted to do this by using thermocouples attached to a multimeter, but they maxed out and melted.

Facing such hassles, most people just change over to using electrical thermocouples.

Mmmm. . . . Well, we could use thermocouples maybe.

As the radioisotope decays, it gives off heat, which the rover converts to electricity using thermocouples.

While the cost, durability, precision, portability, safety and response times of these liquid-column thermometers make them well-suited for laboratory use, other applications call for thermometers that measure temperature using thermocouples, thermistors, linear metallic resistors, bimetals, or electromagnetic radiation.

Temperature sense isn't so important to you, but we used thermocouples for that, and gyroscopes attached to the balance-organ nerves supply a sense of balance.
