One of the most important parts of integrating an inductive sensor into an application or ordering replacement parts is being able to identify the part and model number of the sensor. That is why knowing how to find the model number on your inductive sensor is so important. This is actually a fairly simple and straightforward process.
The Internet of Things is an up-and-coming technology which is set to transform the way we live. Simply put, it allows machines to communicate directly with each other over the Internet. This connection between machines will lead to greater convenience and efficiency based on a more rapid exchange of information. Everyday examples might include a car telling a garage door when to open or close, a stove turning itself on to boil a pot of tea that will be ready for you when you come home from work, a timer setting thermostats, and your refrigerator letting you know when you’re running low on groceries.
Tired of so many different hazardous location wall charts lining your office walls? One for NEC, then one for ATEX, then another one for IECEx, and yet still another for SIL. Just like with most business, it helps when you can one-stop shop; find everything you need at a single supplier. Shouldn’t getting the information you want about hazardous locations be the same?
I should start by mentioning that Pepperl+Fuchs has the pleasure of working with automation engineers every day. They build incredible machines by reducing the most complex problems into a number of simpler tasks. Those tasks are automated, put in sequence, and at the end, they ship a machine that transforms raw material or small components into our everyday items. But, there is one aspect of such machines that is frequently overlooked: diagnostics.
If you scan the Internet for the term Cyber-Physical Systems (or CPS) you will find many contributions discussing topics from mobile phones to time-aware software. CPS are objects that bring the physical (i.e., hardware) together with the computational world. In that sense, a modern car is an application of a CPS.
In communicating systems, bit time is the time it takes for one data bit to be injected into a given network. The main advantage of the bit time concept is that it makes discussions concerning network response times and delays quite easy; in fact, time independent.
Do you need a control panel for installation in a Zone 1 or Zone 2 hazardous area? Unlike the North American Class and Division hazardous area systems, not all Zone areas are created equal.
How do you use this rating to select a sensor?
If you have ever looked at all the data sheet specifications listed for a Pepperl+Fuchs industrial sensor, typically you will see a section labeled “protection degree” under the mechanical specifications section. This rating defines how well the sensor will be protected from contact with dust and water.
It’s no secret that in today’s business world, we must be willing to use the latest technology if we want to maximize our growth potential and stay ahead of the competition. One such promising technology is virtualization.
You may have heard the term before, but you may not know what exactly virtualization is or the benefits it provides. And that’s why I am going to share a brief overview of this innovative technology that we here at Pepperl+Fuchs believe in.
Virtualization gives you the ability to store all of your software and data on a single server outside of a hazardous area even when this server is connected to a thin client or group of thin clients that can be located inside a hazardous area. If a thin client in the hazardous area is damaged, your information is still secure and you can easily replace the damaged thin client. The illustration below shows a virtualized hardware system in which one thin client is outside the network, two thin clients are in good working condition inside the network, and another thin client is damaged with no adverse effect on the information it has gathered.
Because photoelectric sensors are available in such a wide variety of sensing modes (thru-beam, diffuse, retroreflective, etc.), the terms light ON and dark ON were introduced to better define what the sensor’s output is doing in the absence or presence of light. These terms apply only to photoelectric sensors.
Light ON (LO) means that the sensor’s output is only enabled or ON when it receives light. Otherwise, the output remains OFF. Dark ON (DO) means the opposite; when light is received, the output is OFF. The sensor’s output is only enabled or ON when it is dark or when it receives no light. See the figure below for further explanation.
Rather than using the standard convention for describing the outputs as normally open (NO) or normally closed (NC), most photoelectric sensor manufacturers specify the output behavior as being either light ON or dark ON. For most people, this method is more straightforward and easier to understand.
