What is the use of a bimetallic thermometer?
A bimetallic element is used in order to react it from various temperature that will indicated the temperature of an object or body.
What are the function of Bimetallic thermometer?
A bimetallic thermometer has a coil of metal strips in it. The metal strips are made of two different materials that expand/contract at different rates. Because they're connected together at one end, when the metals warm up or cool down, the coil changes shape. You use a bimetallic thermometer when you want an electrical circuit to close due to a change of temperature.
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.
Appliances bimetallic strips are used in?
Bimetallic strips are used in switches which are triggered by changes in temperature. Examples of appliances that use bimetallic strips include heaters, ovens, irons, coffee makers, and toasters. Various applications using bimetallic strips include: 1. Clocks - where temperature changes could cause errors in timekeeping. 2. Thermostats to regulate temperature in household heating systems and car cooling systems. 3. Some thermometers are based on bimetallic strips wound into a coil. 4. Circuit breakers in electrical devices are used to protect circuits from excess current by responding to any increase in temperature by cutting of the electricity supply. 5, Some photocell devices use a thermal relay consisting of a resistor and a bimetallic strip. The light causes the photocell to conduct electricity, causing the resistor to heat, thus causing the bimetallic strip to bend away from the electrical contact, keeping the lights or other load turned off. When it gets dark, the photocell no longer conducts, thus allowing the strip to cool and make contact. This design has advantages over using a magnetic coil relay in that there is some built-in delay and that there may be some inherent overload protection.
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.
Many thermostats use m strip?
Bimetallic strip
Does a barometer use a bimetallic strip?
yes
What is a use of a bimetallic strip in everyday life?
thermostat
Which gadgets use the bimetallic strip?
fire alarm
How could a bimetallic strip be used to help in every day life?
A bimetallic strip can be used as a thermometer or thermostat. The two metals expand at different rates which will make it bend. You can use this to find the temperature of an oven. When the temperature of the oven increases, the strip will curve and break the electrical contact which make the oven cool down. When the oven cools the bimetallic strip will become straight again and the electrical contact will be remade and the oven will begin to reheat again.
Can anyone explain the use of a bimetallic strip in heat regulation in an electric iron?
When the temperature of the iron increases, the bimetallic strip bends upwards. This breaks the contact between the strip and the heating coil. When the temperature falls, the bimetallic strip bends down and the contact is restored.
What is the use of a bimetallic thermometer?

Is it possible to use bimetallic strip to find temperature?
because of pressure
What uses bimetallic strip?
Appliances like electric iron, which need a cut off from the electric current from time to time as the appliance is heated adequately, use bimetallic strip for this.
Can we use bimetallic strip in iron box?
yes, in automated iron boxes

Can a bimetallic strip be made from two strips of same material?
That would be more of a unimetallic strip. No, you need to use two different metals.
