# Industrial Specification: Level Sensor

## 1. Technical Definition
A device that measures and monitors the liquid level within a reagent storage tank.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0-15 m H2O (0-147.1 kPa)**. Failure boundary: **Exceeds 20 m H2O (196.1 kPa) differential pressure or operates below -40°C**, Mechanism: **Diaphragm rupture due to overpressure exceeding yield strength of 316L stainless steel (205 MPa) or diaphragm stiffening below glass transition temperature of FKM elastomer (-20°C)**.

### 2.1 Analytical Physics Model
Governed by the **Hansen Solubility Distance (HSP)**:

> **Primary Equation**: $R_a = \sqrt{4\Delta\delta_d^2 + \Delta\delta_p^2 + \Delta\delta_h^2}$  
> **Engineering Impact**: Predicts seal/gasket swelling when exposed to CIP chemicals.

- **Caution**: 

### Q: Why is 316L stainless steel used for this chemical level sensor?
**A**: 316L stainless steel offers superior corrosion resistance against harsh chemicals commonly used in reagent storage, including acids and chlorides, ensuring long-term durability in chemical manufacturing environments.

### Q: How does the PTFE and ceramic construction benefit chemical level monitoring?
**A**: PTFE (Teflon) provides excellent chemical inertness and resistance to virtually all industrial chemicals, while ceramic components offer thermal stability and wear resistance, making the sensor suitable for aggressive chemical applications.

### Q: What maintenance is required for this level sensor in chemical tanks?
**A**: Minimal maintenance is needed due to the corrosion-resistant materials. Periodic visual inspection of the process seal and calibration checks of the transmitter electronics are recommended to ensure accurate readings in chemical processing applications.
