Experimentation and Application of Differential Inductive System for Machine and Human Body Parametric Measurement

Abstract

In this article, the prototype circuit is constructed and tested to confirm the results obtained through simulation of a differential inductive circuitry. However, some number of errors found are reported in section 7. Analysis is done between the experimentally found results and those obtained from simulation. Test is done on all sections and certain test parameters are set to determine the actual performance of the system. The test parameters are the frequency response of the differential inductive circuit, the oscillatory effect of the movement of the core in and out of the coil, the inductance change, the force/pressure providing motion, wind pressure, the speed of the inward movement of the core and that of the outward movement, the number of turns used, the length of coils, the area of the coil topology, the diameter of the coil and that of the core, the mass of the convulsion bar, the mass of the target, the ambient temperature of the surrounding, density of the magnetic material used, the applied voltage to the timer, the resonant frequency reached, the amount of current voltage and frequency generated, the percentage of the duty cycle found on the resulting signal, the frequency hysteresis found, the range of oscillation bar, the height of coil arrangement, the seesaw concept, the output waveform of the signal, amongst others. The summary of the major contribution of this work includes a novel design of a differential inductive position sensory system along with its model in the form of the sensed parameter equations as a function of the displacement along the length of the coil. The analytical model for linearization compensation and improved transducer response is another component the author of this work claims it as contribution
