Viscosity measurement is important in many process industries

Viscosity measurement is important in many process industries. In the food industry, the viscosity of raw materials such as dough, batter and ice cream has a direct effect on the quality of the product. Similarly, in other industries such as the ceramic one, the quality of raw materials affects the final product quality. Viscosity control is also very important in assembly operations that involve the application of mastics and glue flowing through tubes. Clearly, successful assembly requires such materials to flow through tubes at the correct rate and therefore it is essential that their viscosity is correct.

Torque measurement • Measurement of applied torques is of fundamental importance in all • rotating bodies to ensure that the design of the rotating element is adequate to • prevent failure under shear stresses. Torque measurement is also a necessary part of • measuring the power transmitted by rotating shafts. The three traditional methods of • measuring torque consist of (i) measuring the reaction force in cradled shaft bearings, (ii) the • ‘Prony brake’ method and (iii) measuring the strain produced in a rotating body • due to an applied torque. However, recent developments in electronics and optic-fibre • technology now offer an alternative method •
