Did You Know That Most Sensors Are IO-Link Sensors?

Posted by Tim Cicerchi on Fri, Oct 21, 2016

Many of the sensors you use have IO-Link capability built in. But you might not know it, because they can still be used like standard sensors. For instance, all Pepperl+Fuchs IO-Link sensors boot up first in digital IO mode; they will only switch to IO-Link mode when an IO-Link master actively communicates with them.

Efficient Control Cabinet Wiring with Daisy Chains

Posted by Sonja Armbruster on Fri, Oct 14, 2016

Conventional wiring of hardware components inside a control cabinet can be a complex task: Establishing separate connections of single modules eats up time and precious cabinet space. An effective way to minimize the effort is to interconnect multiple modules using a cable with pre-configured wiring links.

Do I Always Need an AS-Interface Power Supply for My AS-Interface Network?

Posted by Danius Silgalis on Tue, Sep 27, 2016

AS-Interface networks consist of three main categories:

  • Gateways or scanner cards (masters)
  • Power supplies and repeaters (infrastructure)
  • Modules and sensors (slaves)

AS-Interface power supplies supply 30.5 VDC power for nodes connected to the AS-Interface yellow cable.  The decoupling coils in an AS-Interface power supply enable communication and power to be transmitted over a single cable.

4 Different Ways to Program Your Ultrasonic Sensor

Posted by Kamden Payton on Fri, Sep 16, 2016

When working with ultrasonic sensors, programming the sensor is a crucial part of any application. No matter the application, an ultrasonic sensor must be programmed to fit your specific need. Without doing this, you will not be able to use the sensor to its full potential or even set the distance at which it will work. Customers often inquire about how to set a switching distance, incorporate a blind zone, or even change the limits of their analog signal; when questions like this arise, programming is the answer and the cornerstone of any ultrasonic application.

How to Calculate the Maximum Enclosure Size for an Ex pz Purge and Pressurization System

Posted by Brent Dean on Fri, Sep 09, 2016

The maximum size of an Ex pz purge enclosure is determined by the pressure and flow that can be reached inside the enclosure. For this 'how to' post, I'll use our 5500 series purge system for the examples.

Depending on your application, there are three vent options that you can use with your system. The EPV-5500-…-01, EPV-5500-…-02, or EPV-5500-…-03. Each vent opens at a different back pressure and has different flow rates, which are listed below.

Ask an Expert Industrial Sensors - Episode 20

Posted by John Appleson on Thu, Sep 01, 2016

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. Can the inductive sensor NBB1.5-5GM25-E2-V3 detect non-ferrous metals? How does that affect the sensing range?
  2. An inductive sensor won't read above 500 rpm. What's the problem here?
  3. What does the fault error F-4 mean on an AS-Interface network?
  4. Does the MTT-6000 RFID reader need an antenna or read head?
  5. Do you have a capacitive sensor for high temperatures, about 150 °C?

How Are Photoelectric Fork Sensors Different from Normal Thru-Beam Sensors?

Posted by Tom Corbett on Fri, Aug 26, 2016

Fork sensors—when one housing is better than two

Fork sensors, also called fork type sensors or slot sensors, have a unique U shape similar to that of a tuning fork. But don’t be fooled by their name or shape—these are photoelectric sensors that work with light rather than sound. A photoelectric fork sensor is a type of thru-beam sensor with an emitter and receiver facing each other. But instead of the emitter and receiver existing apart from one another as two separate sensors, they are both contained together in the same housing. This one-piece design aligns the optical axis, and with the emitter and receiver perfectly aligned, you get higher switching speeds and better reliability. Finally, since this housing needs only one electrical connection instead of two, the sensor is simpler to install and more cost-effective.

Comparing 3 Different Types of WirelessHART Adapters

Posted by Sabrina Weiland on Fri, Aug 19, 2016

When to use which WirelessHART adapter?

Transmitting small amounts of data over long distances is one of the challenges in process plants. With WirelessHART technology, this can be done efficiently: communicating field signals wirelessly saves time and reduces costs while enabling consistent and safe communication between the field and control side—even in large-scale plants.

Cable Pulls-7 Ways They Pull Their Weight for Rotary Encoders

Posted by Patricia Stafford on Fri, Aug 05, 2016

While many applications use rotary encoders with shafts to monitor rotational speed, some situations call for a different solution—the use of a cable pull.

What all cable pulls have in common is that they are devices that, when used together with rotary encoders, provide precise linear measurements. They are ideal tools for applications where you need information on linear displacement feedback. Cable pulls have a lot to offer when it comes to mobile equipment (including cranes and forklifts), conveyor systems in material handling, safety switches, wind turbines, elevators, and more.
