# Industrial Specification: Feed Sensor

## 1. Technical Definition
A sensor that detects the presence, position, or flow of materials in a product feeder system.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.1-10 m/s material flow velocity, -20°C to 85°C ambient temperature, 12-24 VDC supply voltage**. Failure boundary: **Material flow velocity exceeding 12 m/s causes sensor membrane rupture, ambient temperature beyond -25°C or 90°C causes piezoelectric crystal depolarization, supply voltage below 10.5 VDC or above 26.5 VDC causes Hall effect sensor saturation**, Mechanism: **Membrane rupture due to Bernoulli principle pressure differential exceeding 150 kPa yield strength, piezoelectric depolarization from Curie temperature threshold violation at 90°C, Hall effect sensor saturation from magnetic flux density exceeding 0.5 Tesla at overvoltage conditions**.

### 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 is the feed sensor constructed from?
**A**: The feed sensor features a durable stainless steel housing, a clear polycarbonate lens for protection, and a reliable electronic circuit board for accurate detection.

### Q: How does the feed sensor detect materials in a feeder system?
**A**: The sensor uses its sensing element to detect the presence, position, or flow of materials. The signal processor then interprets this data to provide real-time feedback for system control.

### Q: What are the main components in the feed sensor's bill of materials (BOM)?
**A**: The core BOM includes the sensing element for detection, the signal processor for data interpretation, and the protective housing (stainless steel with polycarbonate lens) for durability in industrial environments.
