LVDT magnetic sensor

 

Project description

The magnetic interference on LVDT position sensors is described through simulations and measurements and an investigation on possible solutions is done. The Ironless inductive position sensor is described as the ideal candidate to totally suppress the interference given by external magnetic fields and perform measurements with an accuracy of a few micrometers. The first prototype shows total DC/low frequency magnetic immunity and an accuracy under the micrometer.
