Technical details and manufacturing context for Data Acquisition System

Definition
Within the Automated Industrial Calibration System, the Data Acquisition System serves as the critical interface between physical measurement devices and the control/analysis software. It continuously samples analog signals from various calibration sensors (temperature, pressure, flow, etc.), converts them to digital format with high precision, and transmits the data to the central processing unit for real-time monitoring, analysis, and calibration verification.
Working Principle
The system operates by connecting to multiple sensors through input channels, sampling analog signals at specified rates, converting them to digital values using analog-to-digital converters (ADCs), applying signal conditioning (filtering, amplification), and transmitting the digitized data via communication protocols (Ethernet, USB, RS-485) to the main control system for processing and storage.
