Instrumentation and control system is the heart of all processing industries. No process can run without the aid of instrumentation. Therefore, sometimes it is said that instruments are eyes of process  through which a process operators visualize the process behaviour. Instrumentation and control concepts have undergone a drastic change over the past few years. The book is meant for the graduate level course of Instrumentation and Process Control (Electrical & Electronics and Instrumentation & Control disciplines).

The topics have been divided in 8 chapters. The first three are devoted to Transducers.
