# Industrial Specification: Level Sensors

## 1. Technical Definition
Devices that detect and measure the level of materials within aggregate bins

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.1-100 mH₂O (differential pressure range), -40°C to 85°C (ambient temperature)**. Failure boundary: **Diaphragm rupture at 150% overpressure (1.5x rated pressure), dielectric breakdown at 2.5 kV/mm for capacitive sensors, piezoelectric crystal depolarization at 350°C Curie temperature**, Mechanism: **Diaphragm fatigue failure due to cyclic pressure loading exceeding 10⁶ cycles at 0.8σ_yield, dielectric breakdown in capacitive sensors from moisture ingress reducing breakdown strength below 0.5 kV/mm, piezoelectric depolarization from exceeding Curie temperature during steam cleaning**.

### 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.
