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
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).
In Metalworking, the clamping status of tools and workpieces are monitored in many applications. Typically, inductive sensors are used to control this. Three positions are usually detected: Unclamped, clamped with object, and clamped without object. The sensor position is mechanically adjusted to the application so the correct clamping process and clamping status is detected with a proper switch point.Read more
