IO-Link Measurement Sensors Solve Application Challenges

In industrial distance and position measurement applications, one size definitely does not fit all.  Depending on the application, the position or distance to be measured can range from just a few millimeters up to dozens of meters.  No single industrial … Continue reading

Magnetic Linear Encoders – Tape Magnetization Technology

Precision Tape Magnetization Leads to Precision Position Measurement The key to ultimate accuracy for any magnetic linear encoder system is the precision of the magnetic encoding on the tape (sometimes called a scale). Sensors inside the encoder read head respond … Continue reading

Open- vs. Closed-loop Control

Several previous articles here on SENSORTECH have mentioned closed-loop control (Servo-Hydraulic Showcase, Linear Feedback Sensor Applications: The Three M’s). But exactly what does “closed-loop control” mean? How does it compare to open-loop control? I recently ran across an article in … Continue reading

3 Production Problems Solved by Intelligent Sensors

In typical sensors all you get is ON or OFF… we just hope and assume that the prox is working, until something doesn’t work properly.  The part is seated but the sensor doesn’t fire or the operator can’t get their machine … Continue reading

You can be doing MORE with Your Sensors!

Recently Hank Hogan published an article in Control Design titled “Sensor, Diagnose Thyself.”  (To be honest, I really wanted to steal his title for my blog entry.)   I think Hank did a great job dissecting the key benefits of smart sensors … Continue reading

The Best Way to Communicate with Smart Sensors

When I am discussing with customers the use smart sensors and smart devices in industrial automation, I always get posed with these questions:

How do the smart sensors interface with the controller?
How do you configure the device?
How do you get diagnostics out of it?
What other information can it provide? Continue reading

Do Photoelectric Sensors Really Measure Up?

I recently spent the week at the IMTS show in Chicago. If you have never been to this show I highly recommend you go in 2012. The show occupied over 1.1 million square feet and there were over 1700 manufacturers … Continue reading

Analog Signals: 0 to 10V Vs. 4-20 mA

In the world of linear position sensors, analog reigns supreme. Sure there are all kinds of other sensor interface types available; digital start/stop, synchronous serial interface, various flavors of fieldbus, and so on. But linear position sensors with analog outputs still account for probably two-thirds of all linear position sensors sold.

When choosing an analog-output position sensor, your choice generally comes down to analog voltage (e.g., 0 to 10 V), or analog current (e.g., 4 to 20 mA). So which should you choose?
