Integrating complex electrical systems and components into hazardous areas typically requires combining different methods of industrial explosion protection to achieve a safe and certified solution. Our Solution Engineering Centers have the ability and the experience as a system integrator for solutions going into Zone 1 and 21 or Zone 2 and 22 areas. Our ATEX and IECEx certificates offer great flexibility, allowing unique solutions for the challenges of putting complex electrical equipment in hazardous locations around the world.
There are times when you need only an intrinsic safety barrier or surge protection to get the job done. But what if you need more than just a component, something more customized, something like a complete system solution—including documentation and certification? Sure, you could always build your own and have it certified yourself. But it's time consuming, and the number of approval standards and certification bodies is enormous. You really need to be focusing on keeping your plant running.
Customized, certified solutions for hazardous locations
In Pepperl+Fuchs lingo, “SEC” stands for Solutions Engineering Center. Our newest SEC location is in Houston, Texas. Other SEC locations include one in Twinsburg, Ohio as well as international locations in England, Germany, Singapore, and Australia.
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.
Lou Szabo, Pepperl+Fuchs Business Development Manager for industrial HMI solutions, is interviewed about 2013 trends in industrial HMI systems, new HMI products - including larger sizes of industrial displays for hazardous areas, and the new VisuNet XT industrial operator workstation, which is designed for use in extreme environments.
VisuNet XT HMI is designed for rig floor use...
At the 2013 OTC show in Houston, TX, Pepperl+Fuchs launched the VisuNet XT, which is our most rugged and innovative industrial operator workstation to date.
Proximity sensors and encoders can have NAMUR output
NAMUR is a type of sensor output that gives an on or off indication. There are different reasons why you may need a NAMUR sensor. I will go through some of them here.
We receive a number of requests each month about connecting a Pepperl+Fuchs industrial HMI workstation to a Rockwell Automation Control System. Some of these installations are upgrades of HMI workstations that have failed, others are new installations. The simple answer is - yes we can!
There are a couple of questions you will need to answer:
Differences between the WPS and WPSA pressure switches
When selecting a Type Y or Type Z purge system, how do you know when to select the WPS (EPSK-1) or WPSA (EPSK-1A) pressure switch, and what is the difference? When selecting which pressure switch to use, first you must determine what hazardous gas group your enclosure is going to be located in (Group A, B, C, D, etc.).
The WPS pressure switch is rated for Class I Division 1 or 2 gas groups C and D. The WPSA switch is rated for Class I Division 1 or 2 gas groups A-D. For gas group C or D, you can use either switch. However, for gas group A or B, you must use the WPSA switch because it is certified for this area.
