# Industrial Specification: Speed Sensor

## 1. Technical Definition
A device that detects and measures the rotational or linear speed of a moving object or system.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0-10000 RPM (rotational), 0-50 m/s (linear)**. Failure boundary: **125°C operating temperature, 1500 g shock acceleration, 95% relative humidity**, Mechanism: **Hall effect sensor saturation at magnetic flux density &gt;0.5 T, piezoelectric crystal depolarization at Curie temperature 350°C**.

### 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.
