Abstract
2.1 EN UN APARATO DE MEDIDA DE GAS CONOCIDO LA PRUEBA DE GAS A MEDIR SE ASPIRA DE UNA BOMBA DE TRANSPORTE DE GAS A TRAVES DE UNA CAMARA DE COMBUSTION, DONDE SE QUEMA UNA PARTE DE LA PORCION DE LA PRUEBA COMBUSTIBLE EN UN SENSOR DE MEDIDA PRECALENTADO. PARA LA SUPERVISION DE LA CORRIENTE DE VOLUMEN, O SI LA CAMARA DE COMBUSTION ES ATRAVESADA O NO POR EL GAS SON NECESARIOS EQUIPOS DE MEDIDA ADICIONALES, QUE CORRESPONDEN A UNA TECNICA DE CIRCUITOS COSTOSA. EL NUEVO APARATO DE MEDIDA DE GAS DEBE PERMITIR, UNA SUPERVISION SENCILLA Y DE COSTE ADECUADO, DONDE SE UTILIZAN LOS ELEMENTOS DE MEDIDA DE GAS YA EXISTENTES. 2.2 PARA LA SUPERVISION DE LA CORRIENTE (14) VOLUMETRICA SE HA PREVISTO UN CIRCUITO DE SUPERVISION (V2, V3, V4 Y 8) INTEGRADO EN EL CIRCUITO DE MEDIDA DEL PUENTE (1) DE MEDIDA, QUE SE COMPONE DE UN SENSOR (2) DE TONALIDAD DE TEMPERATURA CORRESPONDIENTE CON LA SEÑAL DE TENSION Y DEL SENSOR (3) DE CONDUCTIBILIDAD DEL CALOR ASI COMO DE AMPLIFICADORES (V2,V3 Y V4) QUE MIDEN EN LOS SENSORES(8) DE TEMPERATURA SEPARADOS. LOS AMPLIFICADORES ESTAN CONECTADOS EN UNA INSTALACION (9, 10, 11) DE PREPARACION DE SEÑALES. DEBIDO A LAS CORRIENTES VOLUMETRICAS QUE APARECEN SE REFRIGERAN LOS SENSORES (3,4) CALENTADOS, CON LO QUE SE EXPERIMENTA UNAS DISMINUCIONES DE RESISTENCIA, QUE PUEDEN SER MEDIDAS PARA LA DETERMINACION DE LA CORRIENTE VOLUMETRICA EXISTENTE.
