Portable Data Acquisition System

Custom Design Based on GL840 Series Project Description: I designed and developed a portable multi-channel data acquisition system based on the Graphtec GL840 series. The entire setup is custom-built into a durable, shockproof hard case, making it ideal for both industrial and field applications. Highlights: 🔌 20 thermocouple input channels – clearly labeled and designed for quick, secure connections. 🔄 10 BNC connectors – suitable for analog signal acquisition with industrial-grade reliability. 🖥 GL840 display module – centrally located on the front panel for real-time monitoring and control. ⚙️ Integrated 220V AC power input and LAN connectivity – enabling both standalone and networked operation. 📦 DAEHYUN Telemetry System module – an additional integrated telemetry block for extended functionality. 🧳 Compact and portable suitcase design – optimized for transportation, protection, and field deployment. Software & Tools Used: SolidWorks – for detailed 3D modeling and assembly. GL840 software – for real-time data acquisition and exporting (CSV, Excel, USB). Custom electrical layout – for safety, usability, and modular maintenance. Applications: 🔬 Thermal analysis and temperature monitoring 🚘 Automotive testing environments 🧪 Laboratory experiments and scientific R&D 🌿 Environmental monitoring and field diagnostics
