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 topics in the field of engineering as it links the accuracy and quality of instruments thus providing output with an acceptable amount of error. Calibration is the process of configuring an instrument to provide a result for a sample within an acceptable range. Eliminating or minimizing factors that cause inaccurate measurements is a fundamental aspect of instrumentation design (what is calibration?). Say no to plagiarism.

The experiment performed in the laboratory is based on the calibration of a pressure gauge using a dead weight tester. A dead weight tester is a calibration standard that uses the pressure balance principle to calibrate pressure measuring instruments. Uses calibrated weights to apply known pressures to a device under test for a simple, cost-effective solution that covers a wide range of pressure calibrations (deadweight tester). A dead weight tester 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 every portion of the fluid and to the walls of the container” ( Pascal's principle). A dead weight tester consists of a pumping piston with a screw that presses it into the tank containing a fluid oil, a primary piston that carries the dead weight, W, and the pressure gauge or transducer to be calibrated (How to The dead weight tester dead weight works). The primary piston is then loaded with a certain amount of weight W to finalize the desired calibration pressure. Also note that the pumping piston pressurizes the entire system allowing more fluid to enter the cylinder. In this experiment, the Bourdon pressure gauge is connected to a dead weight tester. It contains a transparent dial through which the mechanism is observed. The Bourdon pressure gauge works on the principle that, when pressurized, a flattened tube tends to straighten or return to its circular shape in cross section. The Bourdon tube is available in C-shaped, helical, and spiral shapes, although most pressure gauges use the C-shaped (Flow Control Network) shape. One end of the Bourdon tube is held firmly to introduce pressure while the other end, which is connected to a dial and pointer, can move freely.
