# Industrial Specification: Dancer Arm or Tension Sensor

## 1. Technical Definition
A mechanical-electrical component that measures and regulates material tension in decoiling/uncoiling systems.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.5-50 NÂ·m torque, 0-10 VDC output, -20Â°C to 85Â°C ambient**. Failure boundary: **Permanent deformation at 75 NÂ·m torque, signal saturation at 12 VDC, Hall-effect sensor demagnetization at 125Â°C**, Mechanism: **Yield strength exceedance in 6061-T6 aluminum arm (275 MPa), semiconductor junction breakdown at 15 V reverse bias, Curie temperature transition in NdFeB magnets**.

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

> **Primary Equation**: $F_e = m \cdot r \cdot \omega^2 \sin(\omega t)$
