What Is Purging and Pressurization?
Purging and pressurization is a safe and cost-effective type of explosion protection that allows electrical equipment to be used in a standard enclosure in potentially explosive atmospheres. Find out more about the Ex p type of protection and the functional principle of pressurized enclosures in explosive gas and dust atmospheres in our blog article.
Ethernet-APL Simply Explained—How Parallel Communications Work
Ethernet Advanced Physical Layer, Ethernet-APL for short, is the physical layer for transmitting data into the field of process plants. Learn how parallel communication works today and what possible options there are to access data.
Sinking and Sourcing with Smart Transmitter Power Supply for Analog Input Applications
When selecting an intrinsic safety barrier for an analog input application, one of the biggest issues customers face is differentiating between sinking and sourcing. These terms are used to refer to where the power of the current signal is coming from. Not sure what they mean? Keep reading.
What is Industry 4.0?
What exactly means Industry 4.0? In this blog post, we give an overview of the past Industrial Revolutions that have brought us to this point and outline how Pepperl+Fuchs is involved in Industry 4.0.
How is a type code from Pepperl+Fuchs structured?
How Is a Type Code from Pepperl+Fuchs Structured? Our product portfolio of thousands of sensors includes: inductive, capacitive, magnetic field and ultrasonic sensors as well as sensors for special applications. To help you find the right sensor for your applications, we explain below how a type code from Pepperl+Fuchs is composed. Type codes from Pepperl+Fuchs are composed of three categories for the above sensors: In the first category, a distinction is made between functional principles (sensor type), application-specific features (type of use), installation situation (flush/non-flush) and the sensing distance. In the second category, a distinction is made [...]
What Are the Differences between the K-System and the H-System?
Pepperl+Fuchs offers two extensive product families for safely transmitting signals between the field and control levels: the K-System and the H-System. Get to know the differences between and benefits of these two systems, and explains for whom each system is most suitable.
What Are Industrial Thin Clients? Part 2/2—The Benefits
Over the past decade, thin clients have become more and more popular in process automation and industrial applications. The trend toward virtualization makes thin clients an especially cost-effective solution as they allow users to access applications and information stored on centralized systems such as servers. Learn more about the benefits of thin clients in this blog post.
What Are Industrial Thin Clients? Part 1/2—How It Works
Explosive atmospheres, harsh environments, extreme temperatures—the process industry places unique demands on the people and technology working in the sector. This also applies to thin clients, as they are known in office applications. Unlike traditional PCs, thin clients run applications on remote servers rather than on the local hardware, and only transmit image information and user inputs over the network.
