.~> With additional compensating resistor or resistance element {1}
DEFINITION
Classification: 338/7
(under the class definition) Subject matter wherein the resistance element is formed of materials whose resistance value changes a relatively small amount with a change in the temperature of the element; or wherein one resistance material is combined with another resistance material in the same or different resistance elements, the change of resistance value of one material with the temperature of the material being such as to offset at least partly the change of resistance value of the other material with the temperature of this material, the materials being always at the same temperature, e.g., one material has a positive temperature coefficient and the other material has a correspondingly negative temperature coefficient; or wherein the support or actuator for the resistor includes material or structure which offsets at least partly the effect of or resists dimensional changes due to temperature change in the support or actuator, which otherwise would result in a change in resistance value.
(1) Note. Only compensation structure is classified here which at least partly controls or modifies the resistance value of the resistor. Resistors with temperature compensated supports which merely maintain the position of the resistor unchanged with temperature change, for example, are classified in subclass 316 below.
