# Industrial Specification: Heating/Cooling Actuator

## 1. Technical Definition
A device that converts control signals into mechanical movement to regulate heating or cooling elements within a temperature control system.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.1-2.5 MPa (1-25 bar) working pressure, -40°C to 150°C ambient temperature, 4-20 mA control signal input**. Failure boundary: **Mechanical failure at 3.0 MPa burst pressure, electrical failure at 30 mA continuous current, thermal failure at 180°C actuator body temperature**, Mechanism: **Diaphragm rupture due to yield strength exceedance at 3.0 MPa, coil insulation breakdown at 180°C (Class H insulation limit), potentiometer wiper wear at &gt;100,000 cycles (Archard's wear law)**.

### 2.1 Analytical Physics Model
Governed by the **LMTD Logarithmic Mean Temperature Difference**:
