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.

Industrial RFID: UHF Parameters Revealed

Posted by Tim Cicerchi on Wed, Jan 21, 2015

A UHF RFID system is, “plain and simple,” more complicated to configure and set up than an inductive short-range RFID system.  The Pepperl+Fuchs IUH-F190-V1-FR2-02 read head is a UHF head that makes many of the tough decisions for you.  You don’t need to know about anti-collision algorithms, sessions, inventory queries, or select flags.  We use simple concepts and a reduced parameter list to make it easy for anyone to set up an RFID system.

4 Types of Surge Protection Barriers—Keeping Your Signal Strong

Posted by Patricia Stafford on Thu, Jan 08, 2015

Whether you’re controlling a manufacturing process with a computer, distributed control system (DCS), programmable logic controller (PLC), or field device—surge protection barriers reduce or eliminate the risk to your equipment from lightning strikes and other harmful transient voltage or surge currents.

Below are four types of surge protection solutions, designed for a variety of applications. The common pattern you will see is that for field devices, you need to combine two different types of modules to provide protection. In contrast, a computer, DLC, or PLC requires only a surge protector.

Ask an Expert! Purge Systems - Episode 3

Posted by Kristen Barbour on Thu, Dec 18, 2014

Need help with an industrial purge system or purged enclosure? Ask an Expert! In this episode, Product Manager Brent Dean answers these questions:

  1. For an ATEX installation using purging, can I use a purge system with a standard IP6X enclosure?
  2. Will I need to have a notified body evaluate the final purge system and enclosure even though your purge system carries the ATEX certification?
  3. I have one of your Type Y purge systems and have a request to install an operator interface in a Class I, Div. 1 location. The operator interface is rated Class I, Div. 2. If I use a Y purge unit, will it be considered applicable for the area, or will there be an issue if the display protrudes through the enclosure?
  4. Can a 6000 series Type X purge system be used in a Class I, Div. 2 environment?

5 Ultrasonic Sensing Types that Raise the Bar in Difficult Applications

Posted by Zach Steck on Thu, Dec 11, 2014

Sometimes in life, you just can’t go with the crowd. You need to adapt to new realities, stand out, and become an expert at meeting the unique conditions that you’re facing. When there’s a particular problem to solve, you’re ‘the specialist’ who gets it done right!

If you need an ultrasonic sensor for a particular application, I’d like to introduce you to five sensing types in our ultrasonic sensor family. These problem-solving sensors are designed for specific conditions where an ordinary ultrasonic sensor just won’t do!

Ultrasonic sensors for hazardous locations

In order to be installed in hazardous areas, ultrasonic sensors have to meet specific safety requirements. They must be designed with hazardous locations in mind.

Our HazLoc ultrasonic sensors are UL and CSA certified for use in environments up to Class I, Div. 2.  The Class I, Div. 2 approved models are represented by –HA in the model number.  UC500-30GM-IU-V1-HA is an example.  There is also an –HB model that is usable in all Division 2 areas as well as Class II, Div. 1 and Class III, Div. 1 environments.  The example model number for this type is UC2000-30GM-IU-V1-HB.  All of the hazardous location ultrasonic sensors only have an analog output.  This is selectable for current (4 mA … 20 mA) or voltage (0 V … 10 V).  These sensors also include an M30 to 1/2” NPT adapter for connection through conduit.

Dynamic Leakage Compensation for Seasonal Changes with Type X Purge Systems

Posted by Lou Szabo on Thu, Dec 04, 2014

As we head into winter, many of you with tire pressure monitors will notice the low tire pressure indicator light appearing on your dashboard as the weather turns colder. Wouldn’t it be nice to have automatic pressure compensation for these times?

A mud shaker system manufacturer converted to our 6000 series Type X purge system. There were two major reasons for the conversion.

Life Expectancy of an Inductive Sensor

Posted by David Rubinski on Tue, Nov 25, 2014

What is the working life expectancy of an inductive sensor?

In practical terms, the life expectancy of an inductive sensor is indefinite. This conclusion is based on the operation of the sensor within the specification rating of the product with some margin for improved lifetime usage.


If the sensor is operated at room temperature without the effects of shock, vibration, temperature fluctuations, power supply spikes, or exposure to moisture, the sensor will outlive our life expectancies and may in fact never fail.

For instance, if the sensor is operated at room temperature, 24 VDC supply, and no temperature changes, the sensor may last a lifetime and never fail. This longevity is because the sensor is being operated well within the range of the components used to design the product.

Ask an Expert Industrial Sensors - Episode 6

Posted by John Appleson on Wed, Nov 19, 2014

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'm looking for an ultrasonic distance sensor to beam a signal to the top of a heavy steel column on an elevator (6 meters height). The column base might have some slack jerk. Can fog, gas, vapor, or loud noises affect the ultrasonic sensor?

2. I need updated software to program UC3000 ultrasonic sensors. Is there an update that will allow us to set up these sensors in a Windows 7 program?

3. I would like an ultrasonic sensor that can reliably detect falling objects in a harsh environment (mining operation). We are trying to set off an alarm when there is rock-fall.

4. I have an RFID controller IC-KP-B17-AIDA1 with 4 read heads. We are hooking them up to a 24 VDC power supply and need to know what size/type of fuse to put on the incoming side?

Connecting Field Devices to a Type X Purge System

Posted by Chris Romano on Wed, Nov 12, 2014

Pepperl+Fuchs' 6000 Series Type X purge system has a new intrinsically safe termination board and cable harness kit that makes it much easier to wire field devices to the 6000 Series purge system. The kit includes an IS termination board that is DIN-rail mounted, and a wire harness that can be ordered in three different lengths. Custom lengths are also available. The video below shows you what's in the kit and the steps to take to connect it properly.
