En este trabajo se describe un método para caracterizar la conductividad eléctrica de tubos metálicos sin hacer contacto con ellos. Se  utiliza un circuito LC, a baja frecuencia, para detectar el cambio de inductancia debido a la presencia del conductor en el núcleo de la bobina. Así mismo, se implementa un instrumento virtual en LabVIEW para medir los cambios del promedio de la potencia instantánea en la bobina a partir de las mediciones de corriente y voltaje cuando diferentes materiales conductores se disponen en su núcleo.

 

 

This work aims to present a method to characterize the electrical conductivity of metal tubes without making contact with them. A LC circuit is implemented to detect the change in the inductance due to the conductor material within the coil. Moreover, a virtual instrument created in LabVIEW is implemented for calculating the average value of instantaneous power of the inductor by measuring the current and the voltage when different conductor tubes are placed in the core.
