ELECTROMECHANICAL DEVICE AND METHOD FOR MEASURING THE POWER DRAINED BY FERROFLUIDS APPLIED IN MAGNETIC THERMOTHERAPY.

摘要

The present invention relates to an electromechanical device and a method for measuring the power drained by Ferro fluids applied in magnetic thermotherapy. Said device uses a high frequency alternating magnetic field generator capable of measuring the power transferred to a Ferro fluid of known density, through the measurement of dynamic hysteresis cycles, omitting the use of thermometers. The system characterizes by employing a mechanical positioning system composed of a plurality of supports, covers, and nuts. Said sensors are part of an electronic sensing system including a Hall effect sensor sending the voltage readings induced by the magnetic field and magnetization to an oscilloscope connected to a computer. The RL sensors are configured by firmware from a microcontroller, interconnecting three inductors by ten switches with five variable resistors to execute each one of the stages and steps ordered in the described method.
