Mechanical engineering is a discipline concerned with the application of knowledge to solve real-world problems. The study of calibration techniques is considered one of the most crucial subjects in the field of engineering as it links the accuracy and quality of instruments, thereby providing a result with an acceptable error rate. Calibration is the process of configuring an instrument to provide a result for a sample within an acceptable range. Eliminating or minimizing factors that lead to inaccurate measurements is a fundamental aspect of instrument design (What is Calibration?). Say no to plagiarism.

The experiment carried out in the laboratory is based on the calibration of a pressure gauge using a dead weight balance. A deadweight tester is a calibration standard that uses the principle of a pressure balance to calibrate pressure measuring instruments. It uses calibrated weights to apply known pressures to a device under test to provide a simple, cost-effective solution that covers a wide range of pressure calibrations (dead weight testers). A dead weight works on the principle of Pascal's law which states that "In a fluid at rest in a closed container, a change in pressure in one part is transmitted without loss to each portion of the fluid and to the walls of the container" (Principle by Pascal).A dead weight tester consists of a pumping piston with a screw that presses it into the reservoir containing fluid oil, a primary piston that carries the dead weight, W, and the pressure gauge or transducer to calibrate (How a Dead Weight Tester Works). The primary piston is then loaded with a certain amount of weight W to finalize the desired calibration pressure. It should also be noted that the pumping piston pressurizes the entire system by letting more liquid into the cylinder. In this experiment, the Bourdon gauge is connected to a dead weight tester. It contains a clear dial through which the mechanism is observed. The Bourdon pressure gauge works on the principle that, when put under pressure, a flattened tube tends to straighten out or return to its circular shape in cross section. The Bourdon tube is available in C-shaped, helical, and spiral, although most gauges use the C-shaped (Flow Control Network). One end of the drone tube is held firmly to introduce pressure while the other end, which is linked to a dial and pointer, can move freely..
