# Industrial Specification: I/P Converter

## 1. Technical Definition
A device that converts an electrical current signal (I) into a proportional pneumatic pressure signal (P).

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **4-20 mA input to 3-15 psi output (0.2-1.0 bar)**. Failure boundary: **Input current exceeding 25 mA causes permanent coil damage, output pressure exceeding 20 psi (1.38 bar) ruptures diaphragm**, Mechanism: **Coil overheating due to Joule heating (P=I²R) at 25+ mA causes insulation breakdown at 155°C; diaphragm fatigue failure occurs at 20+ psi due to yield strength limit of 316L stainless steel (205 MPa)**.

### 2.1 Analytical Physics Model
Governed by the **Thin-Wall Pressure Vessel Stress Analysis**:

> **Primary Equation**: $\sigma_h = \frac{P \cdot D}{2t}$  
> **Engineering Impact**: Determines the hoop stress boundary to prevent rupture.

| Symbol | Variable Definition | Localized Reference |
| :--- | :--- | :--- |
| P | Internal Pressure | Engineering Constant |
| D | Diameter | Engineering Constant |
| t | Wall Thickness | Engineering Constant |

### 2.2 FMEA (Failure Mode & Effects Analysis)
| Event Trigger | Severity | Failure Mode | Mitigation Strategy |
| :--- | :--- | :--- | :--- |
| Moisture ingress exceeding 85% RH | 8 | Corrosion-induced short circuit in feedback potentiometer | Hermetic sealing with IP67-rated enclosure and desiccant cartridge |
| Supply pressure fluctuation beyond ±0.5 bar from 1.4 bar nominal | 8 | Nozzle-flapper misalignment causing 0.5 psi hysteresis | Integrated pressure regulator with 0.1% accuracy and 2 μm sintered filter |

- **Caution**: 

### Q: What is the typical input/output range for this I/P converter?
**A**: This I/P converter typically accepts 4-20mA electrical current input and converts it to a proportional 3-15 psi pneumatic pressure output, making it compatible with standard industrial control systems.

### Q: What materials ensure durability in industrial environments?
**A**: The converter features an aluminum alloy housing for corrosion resistance, stainless steel internal components for longevity, copper coil windings for efficient electrical performance, and elastomer seals/diaphragms for reliable pneumatic sealing.

### Q: How does the flapper-nozzle assembly work in this converter?
**A**: The flapper-nozzle assembly converts small electrical signals from the torque motor into precise pneumatic pressure changes. As the flapper moves relative to the nozzle, it modulates air flow to create proportional pressure output through the pneumatic relay.
