12.1 Introduction

When we are to measure any non-electrical quantity like displacement, pressure, temperature, strain, etc., we first convert the measuring quantity into a proportional electrical signal, i.e., voltage or current. This is done with the help of devices called transducers. Therefore, we can state that a transducer is a device which converts a non-electrical quantity ...
