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
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
I am experiencing the future of tradeshows; a networking & educational conference without the travel, the expense, and the suit! I can sit at my desk and make contact with future vendors and customers. Continue reading
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
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?
