A bimetallic strip consist of two metals in order to detect rapid changes in temperature. Used in conjunction with some fire alarm systems, bimetal strips will detect rapid changes in temperature using the differences in expansion rate of the two metals. As one half of the strip expands more rapidly than the other, it will cause the strip to bow or bend causing it to touch a nearby contact sensor thus activating the ' rate of rise' temperature sensor, which may or may not be tied into an alarm system.

What is a bimatallic strip?
A bimetallic strip is a thin strip of two different metals bonded together. The strip bends when heated or cooled due to the different thermal expansion properties of the metals, making it useful in devices like thermostats and temperature-sensitive switches.
How does the bimetallic strip function when heated?
The Bi-metallic Strip works on simple thermal dynamics. 2 different metals are brazed together, and when heated or cooled, the metals expand or shrink at different rates, causing it to move in one direction or the other. they are used in thermostats in kettles and irons and have other useful applications too.
What is bimetallic strips used for?
Bimetallic strips were commonly used in thermostats. The two metals would expand at different rates and therefore bend. When a bimetallic strip, made of iron and brass [or any other metals] is heated, both metals expand differently, causing the bimetallic strip to bend. These bimetallic strips are used in fire alarms. The heat of the fire, causes the brass and iron strips to expand, ultimately resulting in the bending of the bimetallic strip, which on bending touches the screw adjacent to it, thus completing the circuit. Once the circuit is complete, the bell begins to ring. Thus the brass bends more than the steel, but on cooling, contracts more than the steel, thus causing the bimetallic strip to bend in the opposite direction.
What is the use of a bimetallic strip in a thermostat?
The 2 metals have different coefficients of expansion so when the strip heats up it bends. This bending is arranged to separate an electrical connection so that the electrical power causing the heating is switched off, and then back on again when things cool back down slightly.
How does a bimetallic strip works in a thermostat?
The switch contains a sandwich strip of 2 metals with two different coefficients of thermal expansion. The dial you would turn to control the temperature modifies the resistance of the circuit - thus current (or would be set digitally nowadays). When the desired temperature has been reached, one of the metals stretches more than the other. The metal sandwich curls, thus disconnecting the contact of the switch.

How does bimetallic work in an electric iron?
A bimetallic strip is a strip made from 2 different metals. It is designed to bend one way if it is warm and the other way if it is cold. The hotter it gets, the more it bends. In any thermostat, the electrical contacts bend apart as the target temperature is reached. The only difference between a heating thermostat and a cooling thermostat is which side of the bimetallic strip faces the other contact. In a heating appliance, the thermostat knob turns a screw to add resistance to the motion of the contacts so they must get hotter to separate as the screw is tightened. So the tighter the screw is turned, the hotter the appliance is allowed to get before the contacts separate.
Appliances bimetallic strips are used in?
Bimetallic strips are used in appliances for temperature control and safety mechanisms. When the bimetallic strip is heated, the two metals with different coefficients of thermal expansion expand at different rates, causing the strip to bend. This bending action can be used to open or close electrical circuits, regulating the temperature or activating safety features in appliances such as irons, thermostats, and circuit breakers.
What are 2 examples of heat or temperature sensors?
Two examples of heat or temperature sensors are thermocouples, which generate a voltage proportional to temperature differences, and infrared thermometers, which detect infrared energy emitted by an object to determine its temperature.
