# Industrial Specification: Sensor Head

## 1. Technical Definition
The front-end sensing element of a sensor unit that directly interacts with the measured environment or object.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0-150°C, 0-1000 psi, 0-100 kHz**. Failure boundary: **Thermal: 175°C (glass transition of polyimide insulation), Pressure: 1200 psi (yield strength of 316L stainless steel diaphragm), Frequency: 120 kHz (piezoelectric crystal resonant frequency limit)**, Mechanism: **Thermal: Polymer insulation degradation above glass transition temperature; Pressure: Plastic deformation of diaphragm material beyond yield point; Frequency: Mechanical resonance-induced crystal fracture**.

### 2.1 Analytical Physics Model
Governed by the **Combined Measurement Uncertainty**:

> **Primary Equation**: $u_c = \sqrt{\sum u_i^2}$

- **Caution**: 
- **Caution**: 
- **Caution**: 

### Q: What materials are available for sensor head construction?
**A**: Our sensor heads are manufactured using high-grade materials including stainless steel for durability, ceramic for thermal resistance, silicon for precision sensing, and specialized polymers for chemical resistance in harsh environments.

### Q: What components are included in a typical sensor head BOM?
**A**: A standard sensor head bill of materials includes the sensing element that interacts with the environment, a protective housing or sheath for durability, and electrical terminals or connectors for system integration.

### Q: How does the sensor head interface with measurement systems?
**A**: The sensor head serves as the front-end component that directly contacts the measured object or environment, converting physical parameters into electrical signals through its sensing element, which are then transmitted via connectors to processing units.
