Continuous control of process media significantly contributes to the reliability of industrial production. Not only in process industry liquid media are used. More and more process technology is involved in industrial manufacturingRead more
It is not a surprise that optimizing yield is one of the most important objectives in a sawmill (or lumber mill) as it is in any other industry. The big difference is that there is hardly any control over the quality of the logs that enter the sawill.Read more
Do you want to understand the foundations of automation? Is it your job to make production more productive, efficient and secure? Are you asking yourself how to open up the potential of Industry 4.0?
With Basics of Automation we will provide you with the answers. Profit from our knowledge and experience – well-founded, practical, and explained fast and simple.
In the last post about the Basics of Automation, we discussed how humans act as a paradigm for automation. Now, let’s take a closer look at how objects can be detected, collected and positioned with the help of sensors.Read more
Digitizing the production world in the age of Industry 4.0 increases the need for information between the various levels of the automation pyramid from the sensor/actuator level up to the enterprise management level.Read more
Both washdown and hygienic design are common terms used in the food and beverage industry, and are increasingly being used in the packaging industry. These terms are used in different scenarios and easily confused with each other. What exactly are the differences between them, and in what applications are each used?Read more
In my last blog, Imagine the Perfect Photoelectric Sensor, I discussed the possibilities of a single part number that could be configured for any of the basic sensing modes: through-beam, retroreflective, background suppression and diffuse. This perfect sensor would also have the ability to change the sensing mode on the fly and download the required parameters for a changing process or format change.Read more
Here’s a simple way remember how to wire up a 3-wire DC PNP or NPN sensor:
PNP = Switched Positive, NPN = Switched Negative. “Switched” refers to which side of the controlled load (relay, small indicator, PLC input) is being switched electrically. Either the load is connected to Negative and the Positive is switched (PNP), or the load is connected to Positive and the Negative is switched (NPN).
A machine’s automation system operates very much like the human body. Just as we humans perceive our surroundings using our sensory organs, a machine registers its surroundings using presence sensors, input devices, and measuring systems.Read more
