# Industrial Specification: Compaction Meter

## 1. Technical Definition
A measurement device that monitors and displays the compaction level achieved by a vibratory roller during soil or asphalt compaction operations.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0-100% compaction ratio, calibrated to 0.1% resolution**. Failure boundary: **Sensor membrane rupture at 2.5 MPa overpressure or -40°C to +85°C temperature excursion**, Mechanism: **Piezoresistive diaphragm fatigue failure due to cyclic loading exceeding 10⁶ cycles at 10 Hz vibration frequency**.

### 2.1 Analytical Physics Model
Governed by the **Harmonic Vibration Force Generation**:

> **Primary Equation**: $F_e = m \cdot r \cdot \omega^2 \sin(\omega t)$  
> **Engineering Impact**: Calculates centrifugal force for vibratory sifters/feeders.
