# Industrial Specification: Pickup / Sensor Head

## 1. Technical Definition
The detection element of a reference flow sensor that directly interfaces with the fluid or medium to measure flow parameters.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0-150°C, 0-100 bar, 0.1-10 m/s flow velocity**. Failure boundary: **Piezoelectric crystal depolarization at 180°C Curie temperature, diaphragm rupture at 120 bar yield stress, signal attenuation below 0.05 m/s flow velocity**, Mechanism: **Thermal depolarization of PZT-5A piezoelectric elements exceeding Curie temperature, mechanical fatigue of 316L stainless steel diaphragm at 120 MPa stress concentration, boundary layer separation causing turbulent flow detection failure below Reynolds number 2300**.

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

> **Primary Equation**: $u_c = \sqrt{\sum u_i^2}$  
> **Engineering Impact**: Defines the precision confidence interval for inspection.

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

### Q: What materials are available for the pickup/sensor head and when should I choose each?
**A**: Available in 316L stainless steel (general corrosion resistance), PEEK (chemical/corrosive media), and alumina ceramic (high-temperature/abrasive applications). Choose based on your fluid compatibility and operating conditions.

### Q: How does the sensing element interface with different fluids in machinery applications?
**A**: The sensing element directly contacts the fluid through a protective housing/sheath with O-ring seals, ensuring accurate flow parameter measurement while maintaining integrity against pressure, temperature, and medium characteristics.

### Q: What maintenance is required for the pickup/sensor head in industrial equipment?
**A**: Minimal maintenance; periodic inspection of O-rings/seals and housing for wear or buildup is recommended. The robust materials (stainless steel, PEEK, ceramic) provide long service life in harsh machinery environments.

## 6. Manufacturing Compliance
- ISO 10816-1:1995 (VIBRATION MEASUREMENT AND EVALUATION)
