What Is a Zone 1 Div. 1 Industrial Monitor?

Posted by Mark Lovell on Wed, Dec 14, 2016

What Is the Difference Between Zone 1 and Division 1?

A Zone 1 / Div. 1 industrial monitor must meet the requirements necessary for operating in the presence of ignitable concentrations of gases, vapors, or dusts that are likely to exist, either continuously or intermittently, under normal conditions.  That said, the certification requirements vary according to where you will be using your equipment.

What is the difference between Zone 1 and Division 1?

How Does This Affect You?

Basically, the only difference between Zone 1 and Division 1 is that the affected equipment requires different certification based on standards where the equipment will be used around the world. This can be tricky if you need to move equipment internationally. So it would be really nice to have one industrial monitor that could be certified for use almost anywhere in the world.

The Dual-Rated Solution

Dual-Rated Industrial MonitorsAnyone looking for a Zone 1 / Div. 1 dual-rated solution using industrial monitors will be glad to know that the search is over. A globally certified UL Div. 1 / ATEX IECEx Zone 1 industrial touchscreen family is now available—without having to pay for two monitors due to different certification needs depending on location. In the past, there were no single approved touchscreen monitors that could be used in either a Zone 1 or Div. 1 area. As a workaround, it was necessary to use two different products—one for the global Zone market and another for the North American Class and Div. market.

Meeting Zone 1 / Div. 1 Requirements

These monitors are ideal for OEMs, system integrators, and end users looking for a global standard in a process automation environment—particularly in the Chemical, Petrochemical, and Oil & Gas industries.  
 
Using a monitor in a hazardous area gives you immediate access to the process information—and more rapid decision-making and response times, giving you better control of the process. This is crucial for preventing possible faults and for maintaining system availability and for protecting people and equipment.

Have Certification, Will Travel

Because these units are certified for both Div. 1 and Zone 1, it is perfect for movable rig applications. You can transport your oil and gas operations from the Gulf of Mexico to the North Sea, from Texas to Australia, and all the while rest assured that your certification will be recognized with NEC, ATEX, and IECEx markings.

High Visibility Night or Day

Applications located outside often have to contend with harsh sun glare, which can wash out screens and make it hard to see the data. Our monitors come equipped with standard brightness and high brightness options, making them ideal for both indoor and outdoor applications. Sunlight readability provides the intensity and brilliance you need to increase visibility in direct sunlight and other areas where there is high ambient light or harsh glare.

Strong Enough to Handle the Tough Stuff

Monitors used in Zone 1 / Div. 1 locations are rugged and built to last. They can withstand weather extremes / conditions wherever you go. Hardened glass options are available for industrial applications where touchscreen damage is a concern.

With that said, several options can be considered by clicking the links at the end of this post.

NOTE:  You will notice that the monitors described on the web pages below are designated as being for Division 2.  However, each of these monitors can indeed be used in Zone 1 / Div. 1 areas by choosing an intrinsically safe touchscreen and the appropriate certification options, along with installing them in an enclsoure with the appropriate purge system.

The monitors as a whole are mounted within a purged enclosure in a hazardous area that is either general purpose or Division 2 inside the enclosure. The exterior of the enclosure can be a Division 1 or Zone 1 location at that point as the screen itself (not the whole monitor … just the front screen) is an intrinsically safe circuit and thus able to be located within the Division 1 or Zone 1 area.
