With aid of a clearly labeled diagram and explain how a bourdon pressure works?

A Bourdon pressure gauge consists of a curved, hollow metal tube that straightens as pressure increases. When fluid enters the tube, the internal pressure causes it to expand and straighten out, which in turn moves a pointer along a calibrated scale. The amount the tube straightens correlates directly with the pressure, allowing for accurate readings. The diagram would typically show the curved tube, the movement mechanism, and the scale indicating pressure values.
