The fluxgate element is a low field magnetic sensor. Because the magnetic field strenght of a position is a function of its distance to the magnetic source, so the magnetic field strenght of a position can be used for determining its distance to the magnetic source. In this research, the fluxgate element is used to measure the position of a vibrating object as a function of time. Magnetic mass is lying on a cantilever which acts as a spring. Due to periodical external force which applied to the magnetic mass, the cantilever will vibrate with the same frequency as the frequency of the vibrating object. As the magnetic mass vibrates, it will also change its distance to the fluxgate element. The fluxgate element will measure this distance as a function of time. By using a good mathematical sensor model the amplitude and frequency of a vibrating system can be determined. With this model, it has been obtained a vibration sensor with relative error under 4.39%.The developed vibration sensor has resonance frequency close to 38 Hz.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Cantilever,External force,Fluxgate,Fluxgates,Function of time,Low costs,Low field,Magnetic field strenght,Magnetic mass,Magnetic sources,Relative errors,Resonance frequencies,Resonance frequency,Sensor model,Vibrating objects,Vibrating systems,Vibration sensors[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Cantilever,Fluxgate,Resonance frequency,Sensor model,Vibration[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”DOI” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][/vc_column_inner][vc_column_inner width=”1/4″][vc_column_text]Widget Plumx[/vc_column_text][/vc_column_inner][/vc_row_inner][/vc_column][/vc_row][vc_row][vc_column][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][/vc_column][/vc_row]
