In a previous blog post, we looked at the basic operating principle of magnetostriction and how it is applied in a linear position transducer. In this post we’re going to take a more in-depth look at this popular sensing technique … Continue reading
When maintenance technicians replace linear position sensors (also known as probes or wands) from hydraulic cylinders, it can leave a terrible mess, waste hydraulic oils, and expose the individual to harmful hot fluids. Also, the change out process can expose … Continue reading
We all know the roles of mechanical pressure gauges and switches. They either give us a visual indication of hydraulic pressure, or open or close a switch when reaching a certain threshold pressure. Electronic pressure transducers do the same, but … Continue reading
In a previous Sensortech post entitled “Hydraulic Cylinder Position Feedback“, we discussed the basic concept of hydraulic cylinder position feedback. In case you might have missed that post, here it is for an encore appearance. Magnetostrictive linear position transducers are commonly … 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
In a previous installment here on SENSORTECH, we explored the three M’s of linear position feedback application (Linear Feedback Sensors – The Three M’s). One of those three M’s stands for Motion Control. When we talk about motion control applications … Continue reading
Here on SensorTech, we frequently talk about the need for high performance, rugged, reliable position feedback in modern industrial applications. A recent article in Valve Magazine, entitled “The Case for Magnetostrictive” illustrates how linear feedback transducers using non-contact magnetostrictive technology help … Continue reading
I recently ran across an interesting article that explored some of the factors involved in selecting hydraulic cylinders. The article, entitled “3 Steps to Choosing the Right Hydraulic Cylinder” was very informative and helpful. But what if you need a … Continue reading
A question came in recently concerning the maximum recommended cable length for analog sensors. Even as digital interfaces gain popularity, sensors with analog interfaces (0-10V, 4-20 mA, etc.) still represent the overwhelming majority of continuous position sensors used in industrial … Continue reading
