Characteristics And Applications Of Bimetallic Thermometers
A bimetallic thermometer is a mechanical thermometer that has two strips of different metals that have different coefficients of expansion. These metals which are usually steel and copper in the device help in converting the temperature into mechanical displacement. They are attached together by wielding on its length and will expand at different rates as they are heated. Owing to the different properties in the metals, the heat will cause them to bend one way or the other depending on the applied temperature. Applications of bimetallic thermometers Bimetallic thermometers are less expensive and they are durable. At the same time, they are purely mechanical devices that are easy to use. Many industrial sectors use a leading industrial bimetal thermometer that displays the current temperature on their dial. The device is widely used in food processing units, process temperature measurement, wastewater treatment, boiler systems, refineries, and household devices like oven,
