# Industrial Specification: Flame Detector

## 1. Technical Definition
A safety device that monitors the presence or absence of a flame in a burner system.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.1-10.0 lux (flame intensity detection threshold), 400-1100 nm (spectral sensitivity range), -40°C to +85°C (ambient temperature)**. Failure boundary: **Flame signal intensity drops below 0.05 lux for &gt;2 seconds, UV sensor quantum efficiency falls below 15% at 185 nm, IR sensor responsivity drops below 0.5 A/W at 4.3 μm**, Mechanism: **UV sensor quartz window solarization (UV-induced color center formation at 185-260 nm wavelengths), IR sensor PbSe detector thermal degradation (Arrhenius aging with activation energy 0.7 eV), photocathode poisoning from hydrocarbon contamination**.

### 2.1 Analytical Physics Model
Governed by the **Combined Measurement Uncertainty**:

> **Primary Equation**: $u_c = \sqrt{\sum u_i^2}$  
> **Engineering Impact**: Defines the precision confidence interval for inspection.
