Industry 4.0 Comes to Hannover Fair 2015

Posted by Patricia Stafford on Wed, Apr 01, 2015

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.

AS-Interface Safety Monitor Setup Options to Combat Nuisance Shutdowns

Posted by Tim Cicerchi on Wed, Mar 25, 2015

Safety at Work has been a part of AS-Interface for over 10 years now.  It is a very reliable means of networking industrial safety products.  Very demanding applications need extra configuration in the software to prevent nuisance shutdowns.  These shutdowns can be caused by high vibration on the machine opening up mechanical contacts or high noise sources disrupting network communications.  Here are some software settings to reduce or eliminate these nuisance shutdowns.

Fieldbus Physical Layer Diagnostics Saves the Day!

Posted by Andreas Hennecke on Tue, Mar 17, 2015

...and, the goose!

As I was reading John Rezabek's recent article "Can Improved Physical Layer Diagnostics Save Christmas Dinner?", a few thoughts came to mind.

John pointed out that keeping the installation — junction boxes, instrument housings — sealed from moisture ingress is one of the big challenges for both fieldbus and 4 mA … 20 mA installations.

Industrial Displays for Division 2 Hazardous Areas

Posted by Lou Szabo on Thu, Mar 12, 2015

Customers often want to know what exactly is a Class I, Div. 2 industrial display. Or, what choices there are for HMI visualization and machine control in a Division 2 area, and if a purge system is required. The answers depend on what is connected to the display, and the type of HMI software. This information helps you decide whether to look at an industrial monitor, a panel PC, or a networked monitor via thin client or KVM back to a host in a control room.

Using AS-Interface to Control Pneumatically Operated Process Valve Assemblies

Posted by David Fink on Thu, Mar 05, 2015

15 common questions answered about AS-Interface and valve assemblies

1. What is the process valve assembly comprised of?

A typical assembly is a rotary travel valve such as a ball valve or butterfly valve mounted to a pneumatic actuator equipped with a dual position inductive sensor such as our model F31, a target which we call a puck, and a solenoid valve.

How to Connect a NAMUR Sensor to a Switch Amplifier

Posted by Robert Schosker on Thu, Feb 26, 2015

NAMUR sensors are used in hazardous locations, and can provide both explosion hazard and personal safety protection. NAMUR sensors and switch isolators are highly reliable and have proven-in-use characteristics, making them a perfect choice for safety-related applications when connected to suitable control circuits.

Most devices are independently rated with Probability of Failure on Demand (PFD) and Safe Failure Fractions (SFF) that enable them to be used in functional safety areas up to SIL2 or SIL3.. In this video, Product Manager Robert Schosker will show you how to connect a NAMUR sensor to switch amplifier KFA5-SR2-Ex2.W, and then test to ensure proper operation.

5 Reasons Why Thru-Beam Photoelectric Sensors Are Great

Posted by Nick Ferguson on Thu, Feb 19, 2015

Photoelectric sensors are available in a variety of housing styles and operating modes. Background suppression, diffuse, retroreflective, and thru-beam are some of the most common modes. Each mode has unique benefits. This blog discusses the benefits of using thru-beam mode photoelectric sensors.

Is it time to update your modular photoelectric sensor?

Posted by Aaron English on Thu, Feb 12, 2015

How would you like to optimize your sensing capabilities while simplifying your selection process?

Our MP series modular photoelectric sensors provide a unique way to solve applications. Each sensor consists of three separately sold components—a head, a base, and a receptacle. These different combinations offer a wide array of capabilities. With a variety to choose from, you have the ability to customize a sensor that's best for your application.

Ask an Expert Industrial Sensors - Episode 7

Posted by John Appleson on Thu, Feb 05, 2015

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:

1. I want to use a NBB1.5-8GM50-A2-V1 in a safety-related circuit. This circuit will overlap a safety light curtain. I want to use this sensor to monitor the safe position of a pneumatic slice when the light curtain is broken during the loading of a part. The prox signals will be monitored twice per cycle to ensure proper diagnostic coverage. Is it possible to wire two or more of these inductive sensors in a series if I need to monitor the position of more than one device?

2. Does Pepperl+Fuchs have a proximity sensor with a variable output where the output increases as the target cam moves away or toward the target area? The housing has a limitation of 10 mm x 8 cm with a sensing range of 1/16 in. to 1/4 in.

3. An NJ1.5-8GM-N sensor is used in a robot wrist tool changer. The tool is in a harsh environment. The cable is covered with a solvent-proof tube. Is this sensor available with a more durable jacket than PVC? Perhaps a jacket made from nylon impregnated polyurethane?

4. I am wondering what the sensing "cone" angle is on the ultrasonic sensor UB250-F12-U-V15. I have an application that needs to sense levels of liquid in a pan. The sensor would have to be placed close to the wall of the pan. How far away would the sensor need to be from the wall for a given sensing depth?

Smaller Can Be Better with Fiber Optic Sensors

Posted by Tom Corbett on Fri, Jan 30, 2015

Fiber optic sensors sometimes get a bad reputation because of their small size or oddly shaped sensing tips. But, actually, it’s their size and shape that give them unique advantages over typical photoelectric sensors.
