# Industrial Specification: Torque Sensor

## 1. Technical Definition
A device that measures and converts torque (rotational force) into an electrical signal for monitoring and control purposes.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.1-1000 NВ·m**. Failure boundary: **1200 NВ·m (20% over maximum rated torque)**, Mechanism: **Shear stress exceeding material yield strength (П„_max &gt; Пѓ_y/в€љ3 per von Mises criterion)**.

### 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.

- **Caution**: 

### Q: What materials are used in the construction of this torque sensor?
**A**: Our torque sensor features a durable stainless steel and alloy steel housing, strain gauge foil for precise measurement, and electrical insulation materials for reliable performance in industrial environments.

### Q: How does the torque sensor convert rotational force into electrical signals?
**A**: The sensor uses strain gauges bonded to a sensing shaft that deform under torque. This deformation changes electrical resistance, which is then converted into precise voltage signals through the signal conditioning circuit for monitoring and control systems.

### Q: What industries commonly use this type of torque sensor?
**A**: This torque sensor is specifically designed for machinery and equipment manufacturing applications, including industrial automation, production line monitoring, quality control systems, and equipment performance testing where precise torque measurement is critical.
