# Industrial Specification: Position Indicator

## 1. Technical Definition
A visual or electronic device that displays the current open/closed position of a sanitary flow control valve.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0-150°C ambient temperature, 0-100% relative humidity non-condensing, 24VDC ±10% supply voltage**. Failure boundary: **LED burnout at 200mA continuous current, LCD delamination at 85°C sustained temperature, Hall effect sensor saturation at 0.5T magnetic flux density**, Mechanism: **LED junction thermal runaway at 150°C, LCD liquid crystal phase transition at -20°C, Hall effect sensor electron mobility degradation at 125°C**.

### 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.

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

### Q: What makes this position indicator suitable for food manufacturing environments?
**A**: Constructed with 316L/304 stainless steel, food-grade plastics like PEEK and PTFE, and tempered glass, it meets strict sanitary standards, resists corrosion from cleaning chemicals, and prevents contamination.

### Q: How does the position indicator work with sanitary flow control valves?
**A**: It mounts directly to the valve via a bracket, using a position sensor to detect the valve's open/closed status, which is then displayed visually on a scale plate with a pointer or electronically for remote monitoring.

### Q: What are the key components included in the BOM?
**A**: The bill of materials includes a mounting bracket for secure attachment, a pointer/needle for visual indication, a position sensor for accurate detection, and a scale plate marked for clear position reading.
