The 3D design of a gauge illustrates a compact and precise instrument used to measure and display pressure, temperature, or other system parameters in piping and mechanical systems. Typically circular in shape, the model includes a dial face with calibrated markings, a needle indicator, a protective glass cover, and a threaded or flanged connection for installation. Gauges are essential for monitoring system performance and safety in applications such as HVAC, water treatment, oil and gas, and manufacturing. This realistic design supports integration into larger assemblies for simulation and operational planning.
