In this primer you will learn about electrical transducers and get accurate knowledge of the working principle of a transducer. This course explains and defines the parts and functions of a thermistor and a thermocouple. It will also give you information about resistance temperature detectors. You will see how to use a resistive strain gauge learn what a capacitive transducer is and understand linear variable differentials. Next we will discuss the definition of a load cell and a flow transducer. This course also assesses the various measurements of levels and speeds using instruments such as a float level indicator and a stroboscopic tachometer.Next it teaches you about the accurate measurement of torque force and acceleration. You will learn how to correctly use instruments like piezoelectric and magnetostrictive transducers. Furthermore you will learn about the various measurements of acceleration to properly use tools like a linear variable transformer. Following on the material explains how to measure vibration. In addition you will discover how humidity is measured through the use of devices such as a hygrometer. You will be taught how to properly employ a Dunmore cell to measure humidity. The course ends by describing the working principles for measuring moisture and the installation of a transducer.This course provides you with a better understanding of electrical transducers giving you clear and precise methods to apply it in your field. It will help you understand the necessary instruments for measuring electronics and electricity.
