Abstract

PROCEDIMIENTO PARA GENERAR UNA SEÑAL REPRESENTATIVA DE LA SEPARACION ENTRE UN SOPLETE DE CORTE Y UNA PIEZA EN ELABORACION. LA LLAMA DE UN SOPLETE FUNCIONA COMO UNA RESISTENCIA ELECTRICA, DE MANERA QUE HACIENDO PASAR UNA CORRIENTE A TRAVES DE ELLA, APARECE ENTRE SUS EXTREMOS UNA TENSION. ANALIZANDO LA GRAFICA TENSION-INTENSIDAD DE LA LLAMA DE UN SOPLETE, SE OBSERVA QUE EN SU ZONA INTERMEDIA, DONDE LA CORRIENTE ES POSITIVA, LA GRAFICA ES LINEAL Y, POR LO TANTO, EN ESTA ZONA EN LA RESISTENCIA TOTAL SOLO INFLUYE LA DE LA LLAMA, SIENDO PROPORCIONAL A SU LONGITUD. CUALQUIER SEÑAL DE TENSION, OBTENIDA EN ESTA ZONA, ES REPRESENTATIVA DE LA SEPARACION ENTRE UN SOPLETE DE CORTE Y UNA PIEZA EN ELABORACION. N
