Abstract
A temperature measuring device includes a temperature-responsive element that mechanically moves a first inductive assembly component relative to a second inductive assembly component in response to temperature changes. The movement of the first inductive assembly component relative to the second inductive assembly component generates a change in a local eddy current pattern that corresponds to the sensed temperature.
Claims17
A device responsive to temperature change, the device comprising:
- a temperature-responsive element operable to sense temperature and move in response to temperature changes;
- a first inductive component displaceable by the movement of the temperature-responsive element;
- and
- a second inductive component positioned relative to the first inductive component, such that movement of the first inductive component generates a change in a local eddy current pattern corresponding to a temperature change.
