What Are Bars In Espresso Machines?

In espresso machines, the bars are used as pressure indicators for the boiler. The boilers in espresso machines subject water to extremely high temperatures and pressures in order to turn it into steam, which is then utilized in the process of preparing a shot of espresso.

So, what exactly does it mean when an espresso machine refers to a ″BAR″? The term ″BAR″ refers to the unit of measurement for atmospheric pressure, which is also known as barometric pressure.
