bimetallic strip การใช้

• A bimetallic strip thermostat is commonly used as the automatic shut-off mechanism.
• The balance consisted of a circular steel balance wheel with two bimetallic strips attached diametrically.
• Each bimetallic strip terminated with a screw thread mounted with a weight or balance nut.
• Older devices, such as bimetallic strips, were used in conjunction with pilot lights.
• A resettable fuse in series with the cell, particularly of the bimetallic strip type, increases safety.
• Within the device, the very small electric heating element, mentioned above, heats up a bimetallic strip.
• Toasters made since the 1930s frequently use a thermal sensor, such as a bimetallic strip, located close to the toast.
• The earliest surviving bimetallic strip was made by the eighteenth-century clockmaker John Harrison who is generally credited with its invention.
• A bi-metal mechanical thermometer uses a bimetallic strip and bends due to the differing thermal expansion of the two metals.
• Consequently, it takes longer for the bimetallic strip to warp sufficiently to trigger the electric " cut-out " described above.
• Bimetallic strips and disks, which convert a temperature change into mechanical displacement, are the most recognized bimetallic objects due to their name.
• If the engine is started whilst warm the bimetallic strip remains open due to the higher temperature, meaning the cold start routine is not entered.
• It could be a bimetallic strip attached to the on / off switch-- Light current 15 : 49, 22 December 2006 ( UTC)
• When an engine first starts, the coolant temperature is cold and the bimetallic strip is closed, which in turn supplies the cold start injector with current.
• The spiral balance spring also had a temperature compensation device similar to those in Arnold's watches, and based on Harrison's bimetallic strip of brass and steel.
• The thermostat is isolated from the water in the kettle and is instead heated by the steam created when the water boils, which is directed through a duct onto the bimetallic strip.
• A consequence of this design is that the kettle may fail to deactivate if the lid is left open, due to an insufficient amount of steam being ducted onto the bimetallic strip.
• After so many seconds, the bimetallic strip becomes sufficiently warped to trigger a set of spring-loaded switch contacts to open, thus interrupting the electric current to the heating element.
• In addition, the entrance to the vaporising chamber is controlled by a bimetallic strip, which admits more gas to the chamber as it cools, to compensate for the loss of efficiency of evaporation.
• This duration is controlled by the thermotime switch, which is a bimetallic strip based device placed in the water jacket or in the case of an air-cooled engine, in the engine / timing case.
