Pressure transducers find wide spread usage for a variety of applications. In this article, a description of the the historical development followed by the principle of operation of the pressure transducers is given. The characteristics of an ideal pressure transducer for measurement of pressure and the general types of pressure transducer are also given. After description of these basic concepts, the remaining part of the paper is devoted to the various steps involved in the design and fabrication of the pressure transducer. The typical data and performance of the transducer developed are also included. The paper ends with the description on the latest development of pressure transducers viz, the thin film pressure transducers.
