[Music] in this video we're going to introduce you to a very powerful group of devices called smart sensors all right let's go the smart sensor plays a very important role in the smart factory of industry 4.0 which is considered as the fourth revolution of the manufacturing industry the first revolution brought a steam and water-powered mechanization the second revolution introduced mass production using electricity the third revolution established automated manufacturing processes using computers and robotics and now the fourth revolution has launched the internet of things or iot and the smart factory what makes a base sensor different
than a smart sensor before we get to that question let's review what a base sensor is what it does and how it is integrated into process control loops a base sensor is a device that senses something for many years we've had sensors that can see feel hear smell and even taste in the world of instrumentation and process control we define a sensor as a device that detects changes in physical properties and produces an electrical output in response to that change a thermocouple is a temperature sensor that will produce an increasing voltage across it when exposed
to an increasing temperature in industry today thousands of thermocouples are connected to transmitters in temperature process control loops in process control we condition the thermocouple voltage and convert it to an industry standard signal that represents our controlled temperature range okay so what if we had a sensor that did more than sense singular basic physical properties what if we had a sensor that also performs data conversion digital processing and can communicate to external devices in the cloud in very general terms a smart sensor has a base sensor a microprocessor is communication capable and has some form
of on-board diagnostics smart sensors are capable of a variety of functions and options smart sensors can perform self-assessments and self-calibration they can detect issues such as sensor contamination switch failures and open coils some smart sensors are capable of multi-sensing and can measure pressure temperature humidity gas flow and more smart sensors play a very important role in the new era of manufacturing intelligence they will become more and more important as industry develops increasingly sophisticated and complex processes if you want to learn more you might want to review our other video called what is a sensor different
types of sensors and applications you can find the link to this video in the description okay let's review the smart sensor plays a very important role in industry 4.0 which is considered as the fourth revolution of the manufacturing industry a smart sensor can do more than sense singular basic physical properties a smart sensor can perform data conversion digital processing and can communicate to external devices and the cloud a smart sensor has a base sensor a microprocessor is communication capable and has some form of onboard diagnostics sensors are capable of a variety of functions and options
some smart sensors are capable of multi-sensing and can measure pressure temperature humidity gas flow and more newcomers to realpars have free access to one of our online courses you can take advantage of this offer by downloading the realpars app and selecting the first lesson of the plc hardware course just like this video the lessons are all high quality and also very easy to follow also for a low monthly fee you'll get full access to an exclusive library of courses on plc programming and industrial automation topics as well as new fresh out of the oven videos
each and every week these courses are all member exclusive and are not shared anywhere else on the internet [Music] [Music] you
