Robuste Positionsmessung in Hydraulik- und Pneumatikzylindern. Hall-in-one

It has been always important in automation to determine positions accurately, rapidly, and robustly. With its requirements for accuracy this is also the case in automobile engineering. Here analog position registration systems for hydraulic or pneumatic cylinders are needed. A new Hall-based sensor technology uses the principle of measurement of gradients. The discussion covers introduction; the conventional approaches of the Z component and angle; the gradient principle as the new approach; overview of simulation results; and the "Eidhef' sensor research project. The Eidhef project develops a sensor that can deliver 15 linear independent variables. This opens the opportunity for completely novel approaches in the field of position and angle beam sensors
