# Industrial Specification: Leak Sensor

## 1. Technical Definition
A device that detects and signals the presence of liquid leaks in industrial systems.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.1-10 bar (1-1000 kPa) differential pressure**. Failure boundary: **15 bar (1500 kPa) burst pressure or -0.2 bar (-20 kPa) vacuum collapse**, Mechanism: **Diaphragm rupture due to yield strength exceedance (316L stainless steel: 290 MPa yield strength) or capacitive sensor dielectric breakdown (air: 3 MV/m dielectric strength)**.

### 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.
