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.

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.

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.
