Evaluation of a self-correcting dual probe heat pulse sensor

- Knowing probe spacing accurately is important for the dual probe heat pulse method.
- Change in probe spacing can result in large errors in measured heat capacity c.
- In situ probe spacing correction can significantly reduce errors in c.
- Coplanar deflection model works well for small angle non-coplanar deflections.
- In situ correction works well for top deflections than for bottom deflections.
