Mechanical And Industrial Measurements Process Instrumentation & Control

Today the industrial processing and manufacturing techniques have become so much complex and complicated that their control is beyond the reach of human judgement. The automatic controls and protections are inevitable. The exact and precise measurements are the basic essentials of automatic controls. The whole foundation of process industries, power plants and other industries is solely based on the advancement in the art and science of measurements. The quality of the product or the efficiency of production on one hand and the safety (life) of equipment on the other hand, i.e. the concept of optimisation has put such stringent requirements that very accurate and precise measurements are must. The principles underyling the existing techniques of measurements have to be thoroughly understood, the proper selection of the instruments to suit the requirements has to be made, and efforts have to be made to improve upon them and develop new techniques. It is in this direction that the book has been written for.
