# Industrial Specification: Oil Level Indicator

## 1. Technical Definition
A device used to monitor and display the oil level within a reservoir or sump.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0-100% of reservoir height with ±2% accuracy at 20°C**. Failure boundary: **Sensor output deviation &gt;5% from actual level or complete signal loss**, Mechanism: **Capacitance change detection failure due to dielectric constant variation from oil contamination exceeding 15% water content**.

### 2.2 FMEA (Failure Mode & Effects Analysis)
| Event Trigger | Severity | Failure Mode | Mitigation Strategy |
| :--- | :--- | :--- | :--- |
| Dielectric breakdown at 3 kV/mm in contaminated oil | 8 | Capacitance sensor calibration drift exceeding 5% FS | Hermetic sealing with IP68 rating and 316L stainless steel housing |
| Thermal expansion mismatch between 304SS probe and PTFE insulator at ΔT&gt;80°C | 8 | Mechanical binding causing 0-100% stroke restriction | Differential thermal expansion design with Invar 36 alloy compensation |

## 3. Key Technical Parameters

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

### Q: What materials are used in this oil level indicator?
**A**: This oil level indicator is constructed from durable materials including stainless steel for corrosion resistance, polycarbonate for impact resistance, and glass for clear visibility of the oil level.

### Q: How does the oil level indicator work?
**A**: The indicator uses a float mechanism that rises and falls with the oil level, which is then displayed through a sight glass or measured by a sensor, providing real-time monitoring of oil levels in machinery reservoirs.

### Q: What types of machinery is this oil level indicator suitable for?
**A**: This oil level indicator is designed for use in various industrial machinery and equipment including pumps, compressors, generators, hydraulic systems, and other equipment requiring reliable oil level monitoring.

## 6. Manufacturing Compliance
