External Position Feedback for Hydraulic Cylinders
The classic linear position feedback solution for hydraulic cylinders is the rod-style magnetostrictive sensor installed from the back end of the cylinder. The cylinder rod is gun-drilled to accept the length of the sensor probe, and a target magnet is … Continue reading

Level Sensing in Machine Tools
Certainly the main focus in machine tools is on metal cutting or metal forming processes. To achieve optimum results in cutting processes coolants and lubricants are applied. In both metal cutting and metal forming processes hydraulic equipment is used (as hydraulics create high forces in compact designs). … Continue reading

A superior non-contact sensing principle
Magnetostriction is a property of ferromagnetic (iron-based, magnetizeable) materials that causes them to change their shape or dimensions in the presence of a magnetic field. In addition to numerous other practical uses, this magnetostrictive effect is ideally suited for use … Continue reading

Hydraulic Cylinder Position Feedback, Revisited
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

2 Solutions for Preventing Catastrophic Metal Forming Events
Have you ever heard the phrase, “Nine pounds of stuff in a one pound bag?”, or otherwise known as the “Blivet Effect?” I’ve recently experience this, actually four incidences in three different companies to be exact. It revolves the wrong shut height. … Continue reading
