# Industrial Specification: Load Sensor

## 1. Technical Definition
A transducer that converts mechanical load or force into an electrical signal for measurement and monitoring.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0-100 kN with ±0.5% full-scale accuracy**. Failure boundary: **150% of rated capacity (150 kN) causes permanent strain gauge deformation**, Mechanism: **Exceeding the elastic limit of the strain gauge material (typically constantan alloy with 0.2% proof stress of 310 MPa) leads to plastic deformation and signal drift**.

### 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.

| Symbol | Variable Definition | Localized Reference |
| :--- | :--- | :--- |
| u_i | Standard Uncertainty components | Engineering Constant |

### 2.2 FMEA (Failure Mode & Effects Analysis)
| Event Trigger | Severity | Failure Mode | Mitigation Strategy |
| :--- | :--- | :--- | :--- |
| Moisture ingress exceeding 85% relative humidity | 8 | Bridge circuit imbalance causing ±15% signal deviation | Hermetic sealing with IP68-rated epoxy encapsulation and desiccant cavity |
| Thermal cycling between -40°C and +125°C at 10°C/min gradient | 8 | Fatigue failure of solder joints (Manson-Coffin law: Δε_pl = 0.6(N_f)^{-0.6}) | Gold-plated contacts with compliant leadframe design and SnAgCu solder (melting point 217°C) |

**Downstream Applications**: Weighing Scales, Industrial Presses, Material Testing Machines  

## 5. Engineering Risks & FAQ
- **Caution**: 
- **Caution**: 
- **Caution**: 

### Q: What materials are used in your load sensors for durability?
**A**: Our load sensors feature stainless steel and aluminum alloy construction with strain gauge foil elements, providing excellent corrosion resistance and long-term stability in industrial environments.

### Q: How does a load sensor convert force to electrical signals?
**A**: The sensor uses strain gauge foil bonded to an elastic element. When force is applied, the element deforms slightly, changing the electrical resistance of the strain gauge, which is then converted to a measurable voltage signal.

### Q: What components are included in your load sensor BOM?
**A**: Our bill of materials includes the elastic element, strain gauge, protective housing, and cable/connector assembly, ensuring complete functionality and protection for industrial applications.

## 6. Manufacturing Compliance
- ISO 376:2011 (CALIBRATION OF FORCE-PROVING INSTRUMENTS USED FOR THE VERIFICATION OF UNIAXIAL TESTING MACHINES)
- CE MARKING PER EU DIRECTIVE 2014/30/EU (ELECTROMAGNETIC COMPATIBILITY) AND 2014/35/EU (LOW VOLTAGE DIRECTIVE)
