2-7. 스마트 센서 소개

• 영어로 되어있지만, 설명이 간략하고 명확해서 다른 자료 보다 이해 하기 쉽다. 
• Smart Sensor는 기존의 센서보다 많은 기능들이 있기 때문에
• 어떤곳에 적용할 것인가를 고민하면, 비용까지도 줄일수 있다. 
• Smart Factory, 4차 산업혁명의 시작이다. 

 

In this article, we’re going to introduce you to a very powerful group of devices called Smart Sensor.

The 4 Industrial Revolutions

Alright…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 us 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 (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 increasing temperature.

In industry today, thousands of thermocouples are connected to transmitters in temperature process control loops.

In the process control, we condition the thermocouple voltage and convert it to an industry-standard signal that represents our controlled temperature range.

Smart sensor

OK…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 and the Cloud?

What is a smart sensor?

In very general terms a Smart Sensor has a base sensor, a microprocessor, is communication-capable, and has some form of onboard 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.

Smart sensors with multi-sensing capability

Some Smart Sensors are capable of multi-sensing and can measure pressure, temperature, humidity, gas flow, and more.

Manufacturing intelligence

Smart Sensors play a very important role in the new era of manufacturing intelligence. They will become more and more important as the industry develops increasingly sophisticated and complex processes.

Summary

OK, 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.
