Thermal BiMetals
Thermal BiMetals
(OP)
Anyone with any experience using this? Or is there a better forum to ask in?
Specifically, Matweb list two parameters that describe its thermal
characteristics, but I'm unsure of their definition.
1. Specific thermal curvature, /K
2. Specific deflection, /K
Both are unitless (after mutiplying by temp) and both are small numbers
(10^-5). I'm sure that both relate to the differential expansion and #2 is
probably the difference between linear expansion of each metal. But, I have
no idea what #1 is measuring.
I'm also not sure why they are referenced to absolute temperature when they
are spec'd as linear between -20°C and +250°C.
All knowledge, theory and conjecture welcome

Look under Defining Terms at the bottom of the page here:

It is a custom to express temperature differences in celcius as Kelvins as long as it is clear it is a temperature difference and not an absolute temperature.
