In the world of instrumentation and process control, we define a Sensor as a device that detects changes in physical, electrical, or chemical properties and produces an electrical output in response to that change.
This free online course is intended to introduce participants to the various sensors used in industry. After completing this course you'll be able to explain what an industrial sensor is, what it can do, and how it can be used in process control. You’ll also learn the various applications of sensors in industrial environments.
This course also introduces the concept of sensor and transmitter calibration.

Ideal for you if…

  • You are interested in Industrial sensors and different types

  • You are responsible for engineering or maintenance in a plant or field environment

Prepare for better pay & bigger responsibility

Eduardo Cali

I’m a maintenance technician at my company and I recently transferred to automation. We’re working more and more with Siemens so I needed to get up to speed on the newest PLC software. RealPars videos feel like a real classroom experience. The instructors are great…they’re easy to follow and they make the lessons relevant to real-world applications and I like that. I definitely recommend RealPars.

Mario Flores

I tried other online training, but I have to say that RealPars instructors helped me connect the dots in a way the others didn’t. I was able to expand my Siemens knowledge…I only knew Allen-Bradley…now I understand the differences and similarities better. I find RealPars to be a professional and affordable way to get the big picture of PLC as well as gain lots of practical knowledge.
