Abstract

CAMARA DE ENSAYOS PARA SISTEMAS ESTATICOS DE DETECCION DE GASES TOXICOS. ESTA CONSTITUIDA A PARTIR DE UN RECIPIENTE (1), PREFERENTEMENTE DE VIDRIO, CILINDRICO, CON UNA DE SUS BASES SITUADA SOBRE EL CENTRO DEL EJE DE UN AGITADOR (2) Y CON LA OTRA BASE ABIERTA Y ASISTIDA POR UNA TAPA (3) DE CIERRE HERMETICO, A CUYA CARA INTERNA ES SOLIDARIA UNA PLACA SOPORTE (5) SOBRE LA QUE SE INSTALAN DOS CIRCUITOS OSCILADORES (6) PROVISTOS DE SENDOS SENSORES PIEZOELECTRICOS (7) RELACIONADOS CON UNA FUENTE DE ALIMENTACION Y CON UN FRECUENCIMETRO AJENOS A LA CAMARA A TRAVES DE CONECTORES HERMETICOS DE ENTRADA Y SALIDA (8-8'') ESTABLECIDOS EN LA CITADA TAPA (3), EN LA QUE SE SITUA TAMBIEN UN TRANSDUCTOR (9) CONECTADO A LA CITADA FUENTE DE ALIMENTACION Y UN MULTIMETRO DIGITAL. EL RECIPIENTE (1) CUENTA ADEMAS CON UNA BOQUILLA (10) DE CONEXION A UNA BOMBA DE VACIO, Y CON OTRA BOQUILLA (11) QUE PERMITE SU CONEXION OPCIONAL A UNA BALA DE NITROGENO O A UNA DE AIRE SECO, ESTANDO ESTAS BOQUILLAS PROVISTAS DE RESPECTIVAS VALVULAS (12), E INCORPORANDO FINALMENTE DICHO RECIPIENTE (1) OTRAS DOS BOQUILLAS (13) Y (15), LA PRIMERA PARA ACOPLAMIENTO ESTANCO DE UN TERMOMETRO (14) Y LA SEGUNDA PARA INYECCION DE LAS MUESTRAS A ANALIZAR O ENSAYAR, ESTANDO ESTA ULTIMA BOQUILLA (15) PROVISTA DE UN SEPTUM O TAPON DE GOMA (15) QUE ES PINCHADO POR UNA JERINGA EN LA MANIOBRA DE INYECCION DE LAS MUESTRAS.TEST CHAMBER FOR STATIC SYSTEMS FOR TOXIC GAS DETECTION. IT IS MADE FROM A CONTAINER (1), PREFERABLY MADE OF GLASS, CYLINDRICAL, WITH ONE OF ITS BASE SITUATED ON THE CENTER OF THE SHAFT OF A AGITATOR (2) AND WITH THE OTHER OPEN BASE AND ASSISTED BY A CLOSING COVER (3). HERMETIC, TO WHOSE INTERNAL FACE A SUPPORT PLATE (5) IS SOLID ON WHICH TWO OSCILLATOR CIRCUITS (6) ARE INSTALLED EQUIPPED WITH SEVERAL PIEZOELECTRIC SENSORS (7) RELATED TO A POWER SUPPLY AND TO A FREQUENCY METER OUTSIDE THE CHAMBER THROUGH INPUT AND OUTPUT HERMETIC CONNECTORS (8-8'') ESTABLISHED IN THE AFOREMENTIONED COVER (3), IN WHICH IS ALSO LOCATED A TRANSDUCER (9) CONNECTED TO THE ABOVEMENTIONED POWER SUPPLY AND A DIGITAL MULTIMETER. THE CONTAINER (1) ALSO HAS A NOZZLE (10) FOR CONNECTION TO A VACUUM PUMP, AND WITH ANOTHER NOZZLE (11) WHICH ALLOWS ITS OPTIONAL CONNECTION TO A NITROGEN BULLET OR A DRY AIR BULLET, THESE NOZZLES BEING PROVIDED WITH RESPECTIVE VALVES (12), AND FINALLY INCORPORATE SAID CONTAINER (1) ANOTHER TWO NOZZLES (13) AND (15), THE FIRST FOR WATERTIGHT COUPLING OF A THERMOMETER (14) AND THE SECOND FOR INJECTION OF THE SAMPLES TO BE ANALYZED OR TESTED, BEING THIS LAST NOZZLE (15) PROVIDED WITH A SEPTUM OR RUBBER PLUG (15) WHICH IS PUNCTURED BY A SYRINGE DURING THE SAMPLE INJECTION OPERATION.
