A bimetallic temperature gauge is a mechanical temperature measurement instrument that uses the differential thermal expansion of two metals bonded together to detect temperature changes. These gauges are self-operating, requiring no external power, making them ideal for a variety of industrial and commercial uses.
Working PrincipleAt its core is a bimetallic element, usually formed into a spiral or helical coil. This coil is made by bonding two metal strips with significantly different coefficients of thermal expansion (e.g., steel and brass or steel and copper).
-
As the temperature increases, the metals expand at different rates.
-
This causes the strip to bend or twist.
-
The twisting motion is mechanically amplified and transmitted to a pointer on a dial to indicate the temperature.
Typical Metal Combinations:
-
Steel & Brass
-
Steel & Invar
-
Copper & Steel
