Temperature Gauge
A temperature gauge is a device used to indicate the temperature of an item being monitored. The display can be an analogue dial, an analogue range or a digital readout.

Bimetallic strips, whose bending increases with temperature, and thermocouples, which generate an electronic voltage that is temperature-dependent, are common techniques for measuring temperature.
Feature
