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.

High-Capacity RFID Tags

Posted by Tim Cicerchi on Thu, Nov 06, 2014

Industrial RFID systems are composed of a read head, controller, and transponder.  The transponders, or tags, are used to carry information from one process to another.  The RFID tags could require a fixed pallet number that is programmed once, a fixed unique identifier that can’t be written such as a license plate, or a large database of information that describes everything about a specific part or manufacturing process.  This post focuses on high-capacity tag databases.

Ultrasonic Thru-Beam Sensors: Cutting through the Haze

Posted by Patricia Stafford on Thu, Oct 30, 2014

What are ultrasonic thru-beam sensors?

Ultrasonic thru-beam sensors always come in pairs consisting of a dedicated emitter and a dedicated receiver. The evaluation and switching output electronics are located in the receiver. Using Teach-in or a potentiometer, you can adjust the receiver sensitivity for different distances between the emitter and receiver, or for different object sizes.

3 Myths About Industrial Sensors

Posted by Amanda Blakeman on Wed, Oct 15, 2014

Everyone has their own idea of what an industrial sensor is and what it does.  But you might be surprised at how many of these ideas are inaccurate.  Here are several misconceptions about industrial sensors:

Rotary Encoders are Everywhere!

Posted by Nick Ferguson on Wed, Oct 01, 2014

Have you ever entered an elevator and realized that the elevator cart was not level with the floor? Have you ever seen a conveyor system at the airport? What about measuring revolutions per minute or the actual CNC or robot position? What do all of these have in common? Rotary encoders!

Ask an Expert Industrial Sensors - Episode 5

Posted by John Appleson on Thu, Sep 18, 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. What is the slope of the output characteristic, and what is the linearity error value for inductive analog sensor NBB5-18GM60-I3?

2. Are inductive analog sensors, such as the NBB5-18GM60-I3, capable of detecting aluminum at a reduced distance, and do you have a correction factor for this?  

3. Photoelectric sensor MD17/73 has a plastic retaining nut to secure it on a mounting bracket. Is it possible to order just the retaining nuts? Due to location, they get damaged or lost and we don't want to replace the entire switch.

4. Photoelectric sensor - I'm trying to sense clear fluid being shot out of a small 0.11 in. diameter hypodermic needle. What sensor, if any can detect fluid flow start and stop? The water stream is only approximately 0.09 in. in wide.

5. Thru-beam photoelectric sensor - I need to detect wire strands as they pass a sensor. The strands are less than 1 mm diameter, moving up to 5 in./s (~0.13 m/s). Is a thru-beam  photoelectric sensor the best option? Which model would be best for my application?
