Abstract

EN UN DISPOSITIVO DE MEDICION DE POSICION DE LA SITUACION RELATIVA DE DOS OBJETOS (S1, B1), LA DIVISION (T1) DE UN SOPORTE DE DIVISION (TT1), QUE SE COMPONE POR UNA UNIDAD DE PALPADO (AE1B) ESTACIONARIA. MIENTRAS QUE LA UNIDAD DE PALPADO (AE1A) ESTA UNIDA CON EL OBJETO MOVIL (S1), LA UNIDAD DE PALPADO ESTACIONARIA (AE1B), ASI COMO EL SOPORTE DIVISOR (TT1) ESTAN FIJADOS EN EL OBJETO ESTACIONARIO (B1). LA UNIDAD DE PALPADO ESTACIONARIA (AE1B) DISPONE DE UNA UNIDAD DE ALUMBRADO (BE), ASI COMO DOS FOTOELEMENTOS (P1A, P1B) Y LA UNIDAD DE PALPADO MOVIL (AE1A) DE ELEMENTOS OPTICOS (KD, AP, US1, PF). MIENTRAS QUE ENTRE LA UNIDAD DE PALPADO MOVIL (AE1A) Y LA UNIDAD DE PALPADO ESTACIONARIA (AE1B) EXISTE UNICAMENTE UNA UNION DE EFECTO OPTICO, LA UNIDAD DE PALPADO ESTACIONARIA (AE1B) ESTA UNIDA A TRAVES DE UN CABLE ELECTRICA (KB1) CON EL DISPOSITIVO DE VALORACION (AW1), QUE TRANSMITE AMBAS SEÑALES DE PALPADO PERIODICAS (S1A, S1B) DE AMBOS FOTOELEMENTOS (P1A, P1B) AL DISPOSITIVO DE VALORACION (AW1), PARA FORMAR VALORES DE MEDICION PARA LA POSICION RELATIVA DE AMBOS OBJETOS (S1, B1).
