You've committed to the controlled-burn approach. The math is now undeniable. Let's quantify exactly how this fails.
PID control (Proportional-Integral-Derivative) is the gold standard for precision temperature control. Industrial PID controllers achieve ±0.01°C stability. Scientific cryostats reach ±0.001°C. The Flamelock requires ±0.001°C at 47,239°C. That's the same absolute precision as cryostats, but at a temperature 158,647× higher. Relative precision: parts-per-trillion range.
| Sensor | Best Precision | Max Range | At 47,239°C |
|---|---|---|---|
| Thermocouple (Type K) | ±0.5°C | 1372°C | MELTED |
| Thermocouple (Type R) | ±0.5°C | 1767°C | MELTED |
| Radiation pyrometer | ±200°C | ~6000°C | SATURATED |
| Spectroscopic emission | ±50°C | 100,000°C | ±50°C (50,000× too imprecise) |
| Required sensor | ±0.001°C | 47,239°C | DOES NOT EXIST |
There is no sensor in existence that can measure ±0.001°C at 47,239°C. Spectroscopic emission thermometry is your best option and it's 50,000× too imprecise. You cannot control what you cannot measure. This is PID control's fundamental requirement: observability.
