In Metalworking, the clamping status of tools and workpieces are monitored in many applications. Typically, inductive sensors are used to control this. Three positions are usually detected: Unclamped, clamped with object, and clamped without object. The sensor position is mechanically adjusted to … Continue reading
Hydraulic actuators can be used to open and close a valve’s position. In automation architectures, a linear position sensor is used within the hydraulic actuator to provide continuous position feedback. The linear position sensor is installed into the back end … Continue reading
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
External Linear Position Sensors: Floating or Captive Magnet? Linear position sensors that are designed to be mounted externally on a machine (as opposed to those designed to be installed into a hydraulic or pneumatic cylinder) are available in a variety … 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
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
