Certification in Sensors for Manufacturing Automation

Industrial sensors are at the foundation of manufacturing automation, industrial measurement, process monitoring and machine control. This course provides a structured introduction to industrial sensors, transducers, measurement systems, displacement sensors, position sensors, proximity sensors, pressure measurement, flow measurement and temperature sensors, with an emphasis on how different sensing technologies operate and where they are applied.

You will study important industrial sensing technologies including potentiometer sensors, strain gauges, Wheatstone bridges, capacitive sensors, LVDTs, RVDTs, eddy-current proximity sensors, inductive proximity switches, optical encoders, pneumatic sensors, photoelectric sensors and Hall effect sensors.

The course then extends into measurement of important physical and process variables including fluid pressure, liquid flow and temperature, covering technologies such as piezoelectric sensors, turbine meters, bimetallic strips, RTDs, thermistors and thermocouples. Light-sensitive devices including photoresistors and photodiodes are also introduced before the course concludes with sensor selection.

What You Will Learn

The course begins with the foundations of sensors and transducers and their role within measurement systems. You will examine examples and applications of sensing devices before exploring the potentiometer as a practical sensing element.

From there, you will develop an understanding of sensors used for displacement, position and proximity measurement.

You will explore strain-gauge sensing and the use of resistance-based measurement principles, including the Wheatstone bridge. You will then study capacitive sensing elements, their industrial construction and their applications.

The course covers the Linear Variable Differential Transformer (LVDT) and its use for displacement-related measurements. Practical application contexts include roller spacing, injection molding machines and valve opening and closing.

You will also study the Rotary Variable Differential Transformer (RVDT) for rotary measurement and examine additional non-contact sensing technologies such as eddy-current proximity sensors and inductive proximity switches.

Optical sensing is introduced through optical encoders, including their relationship to servo-motor applications. The course also examines pneumatic sensors and proximity switches before moving into photoelectric and Hall effect sensing.

Hall effect sensors are explored from both their operating perspective and their use in industrial monitoring and control applications.

Industrial Pressure and Flow Measurement

Industrial automation frequently requires reliable measurement of physical process variables.

The course introduces fluid pressure measurement and examines the use of an LVDT together with bellows as part of a measurement arrangement.

You will also study piezoelectric sensors, which represent an important sensing principle for converting physical effects into measurable electrical signals.

Tactile sensors are introduced before progressing into liquid-flow measurement.

You will then examine the turbine meter as a method of measuring flow, helping you understand another important category of industrial instrumentation.

The course therefore develops the broader measurement pathway:

Physical Variable → Sensor/Transducer → Measurable Signal → Interpretation → Monitoring or Control

This way of thinking helps connect individual sensor technologies with the larger role of measurement in manufacturing automation.

Temperature Sensors and Temperature Measurement

Temperature is another major industrial measurement variable, and the course covers several important temperature-sensing technologies.

You will begin with the fundamentals of temperature measurement and then study bimetallic strips.

The course introduces Resistance Temperature Detectors (RTDs), including their construction and applications.

You will also study thermistors and their applications, followed by thermocouples and the materials used in thermocouple construction.

These topics provide exposure to multiple temperature measurement principles rather than treating temperature sensing as a single technology.

This makes it possible to understand an important engineering principle:

Measurement Requirement → Sensor Principle → Sensor Characteristics → Application

Displacement, Position and Proximity Sensors

One of the strongest areas of this course is its coverage of sensor technologies used to determine whether an object is present, where it is positioned or how far it has moved.

The course covers:

• Potentiometer sensors

• Strain-gauge sensing elements

• Capacitive sensing elements

• LVDTs

• RVDTs

• Eddy-current proximity sensors

• Inductive proximity switches

• Optical encoders

• Pneumatic sensors

• Proximity switches

• Photoelectric sensors

• Hall effect sensors

This range of technologies demonstrates that there is no single sensor suitable for every industrial measurement problem.

A displacement or position measurement may rely on electrical resistance, capacitance, inductance, electromagnetic effects, optical methods or other sensing principles depending on the application.

Understanding these different principles is important when working with industrial automation systems because the measurement method must match the physical variable and application environment.

Strain Gauges and Wheatstone Bridge Measurement

The course examines strain-gauge sensors across multiple lessons and includes their industrial applications.

You will also study the use of a Wheatstone resistance bridge with strain sensing, helping connect changes in resistance with practical measurement.

The general measurement concept can be understood as:

Physical Change → Sensor Element Response → Electrical Change → Measurement

This relationship appears repeatedly across industrial sensor technologies even though the physical principle used by each sensor may differ.

Capacitive Sensors

Capacitive sensing receives dedicated coverage in the course, including the sensor element, typical industrial construction and applications.

Capacitive sensors demonstrate how changes in electrical properties can be used for measurement and detection.

By studying their construction as well as applications, you gain a clearer understanding of how a sensing principle becomes a practical industrial device.

LVDT and RVDT Sensors

The Linear Variable Differential Transformer (LVDT) is covered together with several application examples.

These include:

• Roller spacing

• Injection molding machines

• Valve opening and closing

• Other LVDT applications

The course also introduces the Rotary Variable Differential Transformer (RVDT), extending the discussion from linear displacement to rotary measurement.

Later, the LVDT principle appears again in connection with bellows for pressure-related measurement.

This reinforces an important concept in instrumentation: the same sensing technology may participate in different measurement arrangements depending on how the physical variable is converted into measurable movement.

Proximity and Non-Contact Detection

The course introduces several technologies relevant to industrial object detection and proximity measurement.

These include:

• Eddy-current proximity sensors

• Inductive proximity switches

• General proximity switches

• Photoelectric sensors

• Hall effect sensors

Understanding the existence of different proximity technologies is important because industrial detection requirements vary according to the target, measurement principle and application.

Rather than viewing "proximity sensor" as one device type, the course helps build an understanding of the different physical principles that can be used to detect or monitor objects.

Optical Encoders and Motion Measurement

The curriculum includes dedicated coverage of optical encoders, followed by further encoder concepts and their use with servo motors.

Encoders are particularly relevant when a system needs information related to movement or position.

Their inclusion alongside LVDTs, RVDTs and other position-sensing technologies provides a broader perspective on the ways industrial systems obtain information about mechanical motion.

Pneumatic, Photoelectric and Hall Effect Sensors

The course also covers pneumatic sensors and their applications, expanding sensor knowledge beyond purely electrical sensing approaches.

Photoelectric sensors introduce light-based detection.

Hall effect sensors introduce magnetic-field-based sensing and are followed by applications and examples involving monitoring or control.

Together, these topics demonstrate how industrial sensing can be based on very different physical phenomena while serving the common purpose of providing useful information to a measurement or automation system.

Pressure Measurement

The fluid-pressure portion of the course introduces pressure as an industrial measurement variable and examines an arrangement involving bellows and an LVDT.

Piezoelectric sensors are also studied within this part of the curriculum.

This reinforces the idea that industrial measurement often involves multiple stages:

Process Variable → Physical Response → Sensor Conversion → Electrical Information

Understanding this chain makes it easier to see how sensors fit into complete measurement systems.

Liquid Flow Measurement

The course introduces liquid flow and then examines the turbine meter.

Flow measurement is important because many industrial processes involve liquids moving through equipment or process systems.

Studying turbine-meter measurement provides another example of how a physical process variable can be converted into measurable information.

RTDs, Thermistors and Thermocouples

Several major temperature-sensing technologies are covered.

RTDs

You will study the construction of Resistance Temperature Detectors and their applications.

Thermistors

The course introduces thermistors together with their applications.

Thermocouples

You will examine thermocouples as well as thermocouple materials.

Studying these technologies together helps learners recognize that temperature can be measured using different physical principles and sensor constructions.

Light Sensors

The course includes photoresistors and their applications, followed by photodiodes and their applications.

These topics extend the curriculum into sensors that respond to light and help broaden your understanding of sensing beyond displacement, pressure, flow and temperature.

Sensor Selection

The course concludes with the important topic of sensor selection.

Learning individual sensor technologies is only part of industrial sensing. A practical measurement problem also requires determining which sensing approach is appropriate for the variable being measured and the intended application.

A useful operating model for approaching sensor selection is:

Measurement Need → Physical Variable → Suitable Sensor Principle → Application Requirements → Sensor Selection

This provides a systematic way to connect the technologies studied throughout the course with real industrial measurement requirements.
