# Industrial Specification: Data Acquisition System

## 1. Technical Definition
A system that collects, digitizes, and transmits measurement data from sensors and instruments in industrial calibration processes.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0-10 VDC analog input, 4-20 mA current loop, -40°C to 85°C ambient temperature**. Failure boundary: **Input voltage exceeding ±15 VDC, sampling rate dropping below 100 Hz, signal-to-noise ratio falling below 60 dB**, Mechanism: **Semiconductor junction breakdown at overvoltage conditions, thermal noise exceeding signal amplitude at high temperatures, analog-to-digital converter saturation beyond input range**.

### 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.
