# Industrial Specification: Conductivity Probe

## 1. Technical Definition
A sensor that measures the electrical conductivity of a solution to monitor cleaning effectiveness in CIP systems.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.1-200 mS/cm at 25°C with ±0.5% accuracy**. Failure boundary: **Electrode polarization occurs at current densities exceeding 0.1 A/cm², causing non-linear response**, Mechanism: **Faradaic electrode reactions at high current densities create concentration gradients and gas bubbles that insulate the electrode surface**.

### 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.

| Symbol | Variable Definition | Localized Reference |
