Ask an Expert Industrial Sensors - Episode 11

Posted by John Appleson on Thu, Jul 23, 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. How do I get a narrower sound cone on an F260 series ultrasonic sensor?
  2. Is AS-Interface "data decoupling" the same as "filter integrated"?
  3. Can I use a diffuse mode photoelectric sensor to detect marks on a steel rivet?
  4. What is the output stage used for on an inductive sensor?
Feel free to ask us your sensing questions, and we'll do our best to reply with the whys and hows of a particular solution.


John: Welcome to Ask an Expert! Hi, this is John Appleson, Marketing Manager with Pepperl+Fuchs. Today, I'm joined by Casey Sutton. Casey works as an Application Engineer here at Pepperl+Fuchs. So welcome, Casey, and thanks for being here!

Casey: Hi John, thanks for asking me.

John: Ok, Casey, let's get started. The customer is asking if there are any additional adjustments to get a narrower sound cone, besides the two potentiometers inside the cover, for an ultrasonic sensor. Casey, any thoughts on this?

Casey: With this model of ultrasonic sensor (UC10000-F260-IE8R2), there are two easy ways to get a narrower cone. The first is to adjust the potentiometer on the unit itself. The second is to use the Ultra3000 software, available on our website, to reduce the cone angle. Either way, the cone can be narrowed by about 10 percent.

John: Alright, this customer would like to know if AS-Interface "data decoupling" is the same as AS-Interface "filter integrated". Can you shed any light on this, Casey?

Casey: In this case, AS-Interface "data decoupling" is the same as AS-Interface "filter being integrated." This technology allows power and data to be transmitted over the same line.

John: This customer has an application where they cut a cross into one end of a steel rivet, so they can flare it out. They'd like to use a sensor that can identify that the cross is present. Casey, what can you recommend?

Casey: This particular application requires a very accurate photoelectric sensor, specifically, one with a very small light spot. In this case, our VT18 series laser diffuse mode sensor can provide not only the accuracy, but the small light spot necessary for this application.

John: Casey, this customer wants to know the output stage of an NJ1.5-V3-N-150-Y45879 inductive sensor, and what it is used for. Casey, can you explain the output stage?

Casey: The output stage for this sensor is a separate amplifier that can be placed far away from the sensing face. This is especially useful in high-heat applications. The sensing face is rated for a far higher ambient temperature than the amplifier. While this particular part number is no longer available, the operation and functionality is similar to that of our F35 series inductive sensors.

John: Well, that concludes this segment of Ask an Expert. I'd like to thank Casey for joining me today, and thank our audience as well.
