bimetal thermometer how it works

How does a bimetal thermometer work? Would you like to measure temperatures mechanically with no use of electricity? In a bimetal thermometer, two metals with

The principle behind a bimetallic strip thermometer relies on the fact that different metals expand at different rates as they warm up. By bonding two different metals together, you can make a simple electric controller that can withstand fairly high temperatures. This sort of controller is often found in ovens. Here is the general layout:

Nov 13,  · The bimetallic strip constitutes one of the most trouble-free and durable thermometers. It is simply two strips of different metals bonded together and held at one end.

The simplest design of a bimetal thermometer is to wrap the bimetallic strip into a spiral. The inner end of the spiral is firmly connected to 

The bimetallic thermometer consists of a bimetallic strip. A bimetallic strip is made of two thin strips of metals which have different coefficients of 

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 thermometers come in externally adjustable or tamper-proof designs. If you need to check and recalibrate the thermometer in the field, 

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.

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 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
