Bi-metallic stem thermometers used to measure the temperature of steamed milk Bi-metallic thermometer for cooking and baking in an oven. There are various kinds of empirical thermometer based on material properties. Many empirical thermometers rely on the constitutive relation between pressure, volume and temperature of their thermometric material.
Working on the principle of a bimetallic strip, it consists of a very slender strip of platinum [1] soldered to a similar strip of silver, with a slip of gold soldered in between. [2] Breguet's thermometer diagram. The strips of soldered metals are curved into a helix (a). The upper extremity of the helix is fastened to a metallic support (c ...
A bimetallic strip is used to compensate this phenomenon in the mechanism of some timepieces. The most common method is to use a bimetallic construction for the circular rim of the balance wheel. What it does is move a weight in a radial way looking at the circular plane down by the balance wheel, varying then, the momentum of inertia of the ...
The bimetallic strip is usually made from steel and copper. Because these metals expand and contract at different rates. When one of these metals expand it curls tighter, when one contracts it uncurls slightly. When it curls or uncurls, the data is converted into electric signals, which record the temperature change.
Early technologies included mercury thermometers with electrodes inserted directly through the glass, so that when a certain (fixed) temperature was reached the contacts would be closed by the mercury. These were accurate to within a degree of temperature. Common sensor technologies in use today include: Bimetallic mechanical or electrical sensors.
"Taylor oven thermometers are always within a degree or two of each other, and from the thermometer in the lid of my grill. I only wish the numbers were a bit easier to read from a couple of feet ...
