# Industrial Specification: Chemical Reactor Temperature Sensor Probe

## 1. Technical Definition
Temperature measurement probe for chemical reactor vessels

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **-50°C to 400°C**. Failure boundary: **425°C for Pt100 RTD sensors, 450°C for Type K thermocouples**, Mechanism: **Phase transformation of platinum wire at 425°C causing permanent resistance shift in RTDs; oxidation of chromel-alumel junction at 450°C creating measurement drift in thermocouples**.

### 2.1 Analytical Physics Model
Governed by the **Hansen Solubility Distance (HSP)**:

> **Primary Equation**: $R_a = \sqrt{4\Delta\delta_d^2 + \Delta\delta_p^2 + \Delta\delta_h^2}$  
> **Engineering Impact**: Predicts seal/gasket swelling when exposed to CIP chemicals.
