Ask an Expert Industrial Sensors - Episode 3

Ask an Expert Industrial Sensors Episode 3

This episode of Ask an Expert for industrial sensors examines and provides answers to interesting sensing questions we've received from customers just like you. We explore and answer these questions:

Purged Industrial Displays for Division 1 Hazardous Areas

Purged Industrial Displays for Division 1 Hazardous Areas

What is the correct purge system to use for a Class I, Div. 1 industrial display?  It’s a common question asked of our technical support experts. Another variation: What choices do I have for HMI visualization and machine control in a Division 1 area and which purge system does it require?

The first two questions to answer are to what is the display connected and what is the HMI software.   This information tells us whether we are looking at an industrial monitor, a panel PC, or a networked monitor via thin client or KVM back to a host in a safe area.

Design criteria

There a few simple ways to get the desired monitor or HMI interface into the hazardous area. For Class I, Division 1, the display requires a hazardous-rated LCD monitor and potentially a small purged enclosure. Peripherals such as barcode scanners, keyboards, etc., also need to be rated for the area.



Double Sheet Sensors… They’re Not Only for Paper

Ultrasonic sensors for double sheet detection

Double sheet sensors originated in the printing industry to quickly and reliably detect the appearance of a double sheet or a splice in the paper.

Spiff Up Your Cubicle with our Hazardous Locations Wall Chart

Spiff up your cubicle with hazardous locations poster

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?

Can Cyber Physical Systems Simplify PLC Logic?

Can Cyber Physical Systems Simplify PLC Logic?

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.

Ask an Expert Industrial HMI - Episode 2

Industrial HMI Questions?

Div. 2 KVM Extenders, Class I, Division 2 Industrial PCs, Zone 1 Remote Monitors, and What's New in 2014!

This is our second installment of Ask an Expert where we sit down with a product expert and answer questions from our customers. Today's expert is Lou Szabo, who is our Business Development Manager for our HMI portfolio.

What Are Rotary Encoders?

What are rotary encoders?

I’ve never been in contact with one before!

Have you ever come across a rotary encoder? Do you know what it does? Rotary encoders are used in everyday machinery. The word rotary means rotational motion. This device operates by detecting the rotation of a disk turning around an axis. Here is some information I found that helped me gain knowledge that will also help you understand.

What Makes a PMI Inductive Sensor Better than a Cylindrical Sensor?

How Do Inductive Sensors Respond to Stainless Steel?

How do inductive sensors respond to stainless steel?

Inductive sensors are designed for the detection of metal targets at close range and are a popular choice for use as proximity switches in factory automation applications.  Carbon steel is the typical target material for these sensors, but in some industries, stainless steel is more common.  There are also certain cases when either both types of steel must be detected by the same sensor, or one sensor is needed to be able to distinguish between the two.
