Is input to a thermocouple a step or ramp?
Click For Summary
Discussion Overview
The discussion revolves around whether the input to a thermocouple, when immersed in a water bath, should be characterized as a step input or a ramp input. Participants explore the implications of thermal mass and response time in this context.
Discussion Character
- Debate/contested
Main Points Raised
- Some participants suggest that the input to a thermocouple can be considered a step input due to the instant change in temperature when immersed in a water bath.
- Others argue that because a thermocouple has thermal mass, the response will take time to settle, which aligns more closely with a ramp input rather than a step input.
- A participant questions the time constant of the thermal change, indicating that the rate of response may influence the classification of the input type.
Areas of Agreement / Disagreement
Participants express differing views on whether the input is best described as a step or ramp, indicating that the discussion remains unresolved.
