Abstract

SISTEMAS DE INSTRUMENTACION Y VIGILANCIA QUE EMPLEAN PERCEPTORES DE DIFERENCIA DE TEMPERATURA. UN PERCEPTOR DE DIFERENCIA DE TEMPERATURA PARA VIGILAR EL NIVEL DE UN FLUIDO EN UN RECIPIENTE A PRESION TIENE TERMOCAVIDADES DE CAVIDAD PARTIDA, CALENTADAS, DE DISEÑO DOBLE, MONTADAS EN LA PARED LATERAL DE UN RECIPIENTE A PRESION Y QUE COMUNICAN POR UNA PENETRACION EN LA PARED LATERAL DEL RECIPIENTE. CADA SONDA TIENE POR LO MENOS UN TALADRO AXIAL PARALELO DENTRO DE ELLA, RECIBIENDO UN PAR SELECCIONADO Y RELACIONADO DE SONDAS RESPECTIVOS ELEMENTOS CALENTADORES Y PERCEPTORES DE TEMPERATURA. LA TEMPERATURA DEL PERCEPTOR DE TEMPERATURA CALENTADO DISMINUYE EN CONTACTO CON AGUA, CUANDO SUBE SU NIVEL. LOS SISTEMAS VIGILAN LAS SALIDAS DE DIFERENCIA DE TEMPERATURA. UNA PLURALIDAD DE PERCEPTORES VIGILAN LAS DIFERENCIAS DE TEMPERATURA PARA PRODUCIR INDICACIONES DE ALARMA Y REALIZAR VERIFICACION DE ERRORES DE LAS INDICACIONES DE SALIDA. APLICACION A LA VIGILANCIA DE REACTORES NUCLEARES Y OTROS.
