Class Information
Number: 338/25
Name: Electrical resistors > Resistance value responsive to a condition > Ambient temperature
Description: Subject matter wherein the resistance element includes material which effects a significant change, such as sharp, rapid, or pronounced, in the resistance value of the element with a change in the surrounding temperature, or together with structure which facilitates this change in resistance value with the surrounding temperature; or including a mechanically adjustable or variable resistor together with structure whose shape, configuration or any other dimension changes with a change in surrounding temperature, the structure being linked with the adjustable or variable resistor to change in resistance value with the change in shape, configuration or other dimension occurring in the temperature sensing structure.
