Where might you see a Bimetallic strip?
old thermostats.
What is a bimetallic strip and where can it be used?
A bimetallic strip is a strip with two metals bonded together. It can be found in thermostats
Many thermostats use m strip?
Bimetallic strip
Why are bimetallic strips used in thermostats?
The two metals chosen for the bimetallic strip have different modulii of thermal expansion, The bimetallic strip bends as the temperature changes and so the strip can be used to activate relays or other electronic switches and so work as a thermostat.
Bimetallic strips composed of two different metals each having a different rate of thermal expansion are used in?
Thermostats,.
A bimetallic strip used in thermostats relies on the fact that different metals have different?
Rates of physical expansion, over the same temperature change.
Any 5 gadgets in which bimetallic strip is used?
They're all thermostats of on kind or another: home, car, stove, hot-water heater,
Why do some thermostats have a spiral shaped bimetallic strip?
That is what makes the thermostat works, the two different metals expand and contract with the temperature and trigger the heat or air
Why do some thermostats have a spiral shaped bimetallic?
Its just a different type of temperature measurement, the coil expands or contracts at a steady rate so it is reliable for setting a temp range.
Bimetallic Controls In Furnance Thermostats?
Voltage is reduced to levels of 12 or 24 volts for furnace thermostats servicing digital, electronic programmable or mercury contact controls. Line voltage thermostats operate with adjustable potentiometers. The mercury contact operates on the principle that some metals expand when heated. By tapping the precise amount of expansion, a hotter temperature could force the metal to expand so that a vial of mercury is tipped. The tipping action closes or opens a switching ensemble that can turn the burner in the furnace on or off. The mercury vial could be replaced entirely by the operation of the simple bimetallic cord.
What happens when bimetallic strip is heated?
The bimetallic strip bends.
How does a bimetallic strip act as a switch?
It acts as a switch in thermostats because it starts curved and when it cools down enough for it to straighten up it touches another piece of metal, completing a circuit before bending again due to the heat. Hope this helped!
