Course content

2 sections • 5 lectures • 1h 16m total length

  • Basic types of transducers20:54

    Transducers convert physical energy into electrical signals and are classified as Active or Passive, with ideal ones being linear, repeatable, and hysteresis-free.


    Capacitive types measure displacement via area/distance/dielectric changes, while Inductive types (especially LVDT) use electromagnetic induction through coil geometry.

  • THERMOELECTRIC C PHOTOELECTRIC TRANSDUCERS12:29

    Thermoelectric transducers (RTD, Thermocouple, Thermistor) convert temperature to electrical signals — Thermocouples via Seebeck Effect, Thermistors via sharp NTC/PTC resistance changes.


    Photoelectric transducers convert light to electrical signals — LEDs/Laser Diodes emit via p-n junction, while Photodiodes/LDRs sense light through photocurrent or resistance change.

Description

Welcome to Sensors & Measuring Instruments Made Easy

This course is specially designed for beginners, diploma students, engineering undergraduates, and anyone interested in learning the fundamentals of measurement and sensing technologies. The course provides a clear and easy-to-understand introduction to transducers, sensors, and measuring instruments that are widely used in modern electrical, electronic, industrial, and automation systems.

You will begin by understanding the basic concepts of transducers and their role in converting physical quantities into measurable electrical signals. The course then explores different types of transducers, including capacitive, inductive, thermoelectric, photoelectric, optoelectronic, piezoelectric, and Hall-effect transducers. Their working principles, construction, characteristics, advantages, limitations, and practical applications are explained with simple examples.

In addition, you will learn about Analog and digital measuring instruments such as PMMC instruments, moving iron instruments, dynamometers, digital multimeters, and digital storage oscilloscopes (DSO). The course also introduces modern sensors, including proximity sensors, infrared sensors, pressure sensors, biosensors, and smart building sensors used in real-world engineering applications.

Each topic is presented in a structured and beginner-friendly manner with illustrations, comparisons, quizzes, and practical insights to enhance learning. By the end of this course, you will have a solid understanding of measurement systems and sensor technologies, enabling you to confidently apply these concepts in academic studies, laboratory experiments, projects, and industry-orientated applications. You will also gain the knowledge required to understand sensor-based systems used in automation, smart devices, and Industry 4.0 applications.

Whether you are preparing for examinations, academic projects, or a career in engineering, this course will provide a strong foundation in instrumentation and measurement technology.

Who this course is for:

  • This course is ideal for beginners, engineering students, diploma learners, hobbyists, and anyone interested in sensors, instrumentation, electronics, and automation technologies.
