Abstract
SE TRATA DE UN SENSOR QUE PRODUCE UNA SEÑAL DE SALIDA PROPORCIONAL A LA RELACION ENTRE LA PRESION EN LA LINEA Y LA TEMPERATURA DEL GAS QUE FLUYE EN ESTA LINEA (10), PARA UTILIZAR EN LA CORRECCION DE SALIDA DE UN CUADALIMETRO CONECTADO A LA LINEA (10). ESTE SENSOR CONSTA DE UNA CAMARA PRECINTADA (14), QUE CONTIENE UNA MASA FIJA DE UN GAS DE REFERENCIA. LA CAMARA PRECINTADA (14) INCLUYE UNA PARTE (15) SOMETIDA A LA PRESION DE LA LINEA, MANTENIENDO ASI EL GAS DE REFERENCIA A LA PRESION DE LA LINEA. ADEMAS LA CAMARA PRECINTADA (14) ESTA AISLADA TERMICAMENTE E INCLUYE, POR LO MENOS, UNA PARTE INSERTADA EN UN HUECO TERMICO EN LA LINEA (10), CON EL FIN DE MANTENER EL GAS DE REFERENCIA A LA MISMA TEMPERATURA DE LA LINEA. UN SENSOR DE DENSIDAD DE CUARZO QUE VIBRA (101) SE MONTA TAMBIEN EN EL HUECO TERMICO PARA PRODUCIR UNA SEÑAL DE SALIDA, CUYA FRECUENCIA ES PROPORCIONAL A LA DENSIDAD DEL GAS DE REFERENCIA, LA CUAL PUEDE SER PROPORCIONAL, A SU VEZ, A LA RELACION ENTRE LA PRESION Y LA TEMPERATURA DELA LINEA.
