Prototype Dead Weight Tester

Dead Weight Tester is a pressure calibration device designed to generate highly accurate pressure using the balance principle between force and piston area. This instrument is commonly used in instrumentation laboratories and industrial applications for calibrating pressure gauges, pressure transmitters, and other pressure measurement devices. This model was created as a technical representation of a Dead Weight Tester system with detailed mechanical components and assembly-oriented design for CAD and engineering learning purposes. The design includes the main body structure, piston-cylinder mechanism, and calibrated weight placement system based on real industrial concepts. Suitable for: • CAD modeling practice • Mechanical assembly study • Instrumentation engineering reference • Technical drawing learning • Reverse engineering projects The model is developed with an engineering-focused approach to provide realistic mechanical proportions, structural details, and technical visualization.
