Scientists at the University of Central Florida in the US are inventing a small device that will be able to more accurately measure combustion temperatures, removing the need to take readings from elsewhere.

The three-year project involves designing a thermometer that will last years inside a power plant.

Electrical engineer Xun Gong and two other professors in collaboration with Siemens Energy said the temperature sensor will be used in power stations that operate on natural gas.

The sensor uses a heat-resistant enhanced ceramic designed by the UCF team.

The device will release a wireless microwave temperature signal that can be spotted outside the combustion chamber.

The system will be operate at temperatures up to 2,700°F.
