How Bimetallic Temperature Gauges Works !! ||Engineer's Academy||

[@matthachireth4976]

We required few cold control bi-metalic strips.When the room temperature reach +20 degree ,the fan must be off.

good job

Doctor here, watching your video

[@shrikantthakare9569]

Which two metals are used in that stem ?

[@Gato_armado]

Hi. I 've one in the oven. Why the bimetalic termometer don´t return to 0° when it's off?

[@EngineersAcademy9204]

Hi... How it will come to zero .. it will return to ambient temperature !! Like atmosphere temperature.

[@ArbathSahadewa]

Is that mean, if the glass broke, it still work?

[@EngineersAcademy9204]

Yes

[@ArbathSahadewa]

@@EngineersAcademy9204 thank you very much 🙏

Excellent video, very informative...but Sirji, you are using the word "GUYS" more than several times...

You didn't really explain why a single the use of bimetallic strips are better suited for thermostats rather than single strips. All you said is that single strips don't move as quickly, but why? Your example of a heated ball not fitting through a circular loop does nothing to prove that point. Can you elaborate as to why single strips are more ineffective than a bimetallic setup?

Different co efficient of thermal expansion

[@srinivassai6372]

The main reason behind using the bimetal is as follows...if we use a single metal then the expansion is too small to notice unless the sample size is high...as the expansion is microscopic it is difficult to calibrate...instead if we use two metals having higher and lower coefficient of expansions...the difference in the expansions makes the strip to bend such that makes the deflection detectable
