Abstract

SISTEMA DE CALIBRACION PARA UN TRANSDUCTOR DE LA TENSION ARTERIAL QUE SE UTILIZA PARA CALIBRAR UNA COMBINACION DE TRANSDUCTOR Y MONITOR DE LA TENSION ARTERIAL. EL CONJUNTO DEL TRANSDUCTOR TIENE UNA RESISTENCIA DE CALIBRACION. EL CABLE DEL MONITOR TIENE UNA CAJA QUE CONTIENE UN INTERRUPTOR Y UNA RESISTENCIA EN DERIVACION O <SHUNT>. EL APARATO TIENE CONEXIONES ELECTRICAS PARA PONER LA RESISTENCIA DE CALIBRACION Y EL <SHUNT> EN SERIE ENTRE SI Y EN DERIVACION A TRAVES DE UN TRAMO DE UN PUENTE DE TRANSDUCTOR PARA PRODUCIR UNA LECTURA DE 100 MMHG EN EL MONITOR.
