Abstract

The invention relates to a method and a device for applying a controlled and/or temperature-controlled air flow to a sensor reacting to pollutants, in particular for use in protective cabins, for example the cabins of motor vehicles. It is known to use sensors for the display of gaseous pollutants on LEDs or for initiating switching processes. In order to avoid display-displacements of the sensor for different air speeds, according to the invention it is proposed that a pulsating air chamber (5) whose pulsation element (7) has asymmetrical flow profiles be connected upstream of the sensor (1) and that a dense air flow, produced by the pulsator (8) should take place through the measurement opening (9) as a result of the pulsation movement. In the sensor housing, an air-conditioning system (10) is arranged. <IMAGE>

Description

Besehreibung und Erläuterung zur PatentanmeldungDescription and explanation of the patent application

Gehäuse für Sensoren, vorzugsweise für den Einsatz von Arbeitsschutzkabinen bei Kraftfahrzeugen mit geregelter und temperierter Luftmenge" Es ist bekannt, Sensoren mit Anzeige von gasförniigen Schadstoffen über Leuchtdioden oder Schaltvorgänge zu nutzen.Housing for sensors, preferably for use in work safety cabins in motor vehicles with regulated and tempered air volume "It is known sensors with display of gaseous pollutants via light emitting diodes or switching processes to use.

Diese Sensoren werden in der Regel in Gehäusen, rein mechanisch geschützt eingesetzt.These sensors are usually protected mechanically in housings used.

Es ist weiterhin bekannt, eine Temperaturkonstante für den Sensor dadurch zu erzielen, daß Heizflächen-Anordnungen in Sensorgehäusen angesetzt werden, Jedoch das Anströmen des Sensors bei den verschiedenen Geschwindigkeiten erzeugt zwangsläufig unterschiedliche Luftmengen, die am Heizsystem des Sensors vorbeistreichen, und infolgedessen der Sensor mit unterschiedlichen Temperaturen arbeiten muß.It is also known a temperature constant for the sensor to achieve that heating surface arrangements are placed in sensor housings, However, the flow onto the sensor is generated at the different speeds inevitably different amounts of air that sweep past the heating system of the sensor, and, as a result, the sensor with different Temperatures have to work.

Das führt zwangsläufig zu Anzeigeverschiebungen, die nicht gewünscht werden, z.B. Einschalten eines Schadstoffilters über die Sensorsteuerung.This inevitably leads to display shifts that are not desired e.g. switching on a pollutant filter via the sensor control.

Auch die Anzeigenregulierung von Frischluftklappen und dergleichen ist zu sehr differenziert, wenn nicht die Möglichkeit gegeben ist, den Sensor diesen äußeren Schwankungen zu entziehen, oder daß dadurch seine Anzeige zu träge wird.Also the display regulation of fresh air flaps and the like is too differentiated if it is not possible to use the sensor to withdraw external fluctuations, or that this makes its display too sluggish.

Aus diesem Grunde wird erfindungsgemäß vorgeschlagen, eine Sensor-Anordnung entsprechend der beiliegenden Zeichnung vorzunehmen.For this reason, a sensor arrangement is proposed according to the invention to be carried out according to the accompanying drawing.

In der beiliegenden Zeichnung ist dargestellt: Abb. A mit (1) der Sensor; mit (2) das Sensorgehäuse; mit (3) die einströmende Luft, die über den schwingenden Kolben (7) und über (10) einen Luftkonditionierungsblock (z.B. Lufterwärmer) über die Meßöffnung (9) dem Sensor zugeführt wird.The accompanying drawing shows: Fig. A with (1) the Sensor; with (2) the sensor housing; with (3) the incoming air, those via the oscillating piston (7) and via (10) an air conditioning block (e.g. air heater) is fed to the sensor via the measuring opening (9).

An der Öffnung (6a) und (6b) kann die Luft aus dem Gehäuse entweichen, nachdem sie meßtechnisch für den Sensor über den Kontrollraum (5) wirksam geworden ist.The air can escape from the housing at the opening (6a) and (6b), after it has become effective for the sensor via the control room (5) is.

Die Zuführung der Luftmenge, die zur Messung zur Verfügung steht, erfolgt erfindungsgemäß in einfachster Weise durch einen schwingenden Kolben (7) gemäß Abb. A + B, der eine asymmetrische, vorzugsweise sägezahnförmige Ausführung am Umfang aufweist, damit in unterschiedlichen Richtungen unterschiedlich starke Strömungswiderstände erzeugt werden, so daß bei der Schwinbewegung durch den Schwinger (8) eine vorbestimmte Luftströmung erzeugt wird, und die zuzuführende Luft bei (3) in das Gehäuse eintritt.The supply of the amount of air that is available for measurement, takes place according to the invention in the simplest way by a vibrating piston (7) according to Fig. A + B, which is an asymmetrical, preferably sawtooth-shaped design has on the circumference, so that different strengths in different directions Flow resistances are generated, so that during the oscillation movement by the oscillator (8) a predetermined air flow is generated, and the air to be supplied at (3) enters the housing.

Ebenso ist erfindungsgemäß die Öffnung (3) diffusorartig ausgebildet, so daß auch im Ansaugbereich verdichtet Strömungswiderstände auftreten, so daß bei der durch den Schwinger verursachten Luft pulsierung genügend Luft eintritt, um eine genügend hohe Bespülung des Sensors zu erzielen.According to the invention, the opening (3) is also designed like a diffuser, so that also in the intake area condensed flow resistances occur, so that with the air pulsation caused by the transducer enough air enters, in order to achieve a sufficiently high level of purging of the sensor.
