A bimetallic coil from a thermometer reacts to the heat from a lighter, by uncoiling and then coiling back up when the lighter is removed. The invention of the 

Hello Everyone Welcome to Engineer’s AcademyIn this video we will learn the Working of bimetallic Temperature Gauge, It’s Construction & Specifications. Also

Sep 14,  · The defrost bimetal thermostat does this by activating a hot gas valve or an electrical heating element that raises the temperature near the evaporator, which then melts the frost that has formed. The melting away of frost buildup protects your refrigerator and freezer's evaporators from overheating during the defrost cycle.

Bimetal thermometers work on the principle that different metals expand at different rates as they are heated. By using two strips of different metals in a thermometer, the movement of the strips correlates to temperature and can be indicated along a scale.

The bimetal thermometer employs a bimetal strip in the form of a helix; It works on the principle of thermal expansion - two metals with different coefficient of expansions are joined to form a bimetal. The expansion of bimetal is proportional to temperature; Bimetal dial thermometers are simple in construction, yet rugged.

Bimetal thermometers are designed with a bimetal strip and it is wrapped into a helical coil. The helical bimetal is connected at one end in a measuring tube. A 

Bimetal Thermometer works with two pieces of metal with different thermal expansion inside the shaft. Continue reading our post.

Nov 02,  · Bimetal temperature gauges are generally produced as a helical tube. The measuring system consists of two strips of metal with different expansion coefficients that are welded or bonded. When the

Bimetal thermometers work on the principle that different metals expand at different rates as they are heated. By using two strips of different metals in a thermometer, the movement of the strips correlates to temperature and can be indicated along a scale. Bimetal thermometers are inexpensive, simple, and durable.

Bimetal thermometer is a temperature measuring device. It uses a bimetal to convert the temperature of the medium into mechanical displacement. The bimetal 

The bimetal thermometer has been used by humans for over 200 years and continues to be an accurate and reliable source to gauge the temperature of food or other materials. You can use a number of different metals to make this thermometer work, but it is important to be sure that one of the metals has low heat sensitivity and the other is high heat sensitivity. They are designed to bend and expand when heated.
