Bei der Kontrolle chemischer Reaktionen werden üblicherweise spektroskopische Sonden oder Ultraschallsonden, z. B. auf Reaktionskesseln, fest installiert, ohne eine Reinigungsmöglichkeit der Sonde im laufenden Prozeß zu haben. Gegebenenfalls ist die Sonde in eine Nebenleitung (Bypass) zum Reaktor eingebaut, der eine zeitweilige Abkopplung vom Prozeß und eine Reinigung der Sonde erlaubt. Nebenleitungen in Produktionsanlagen sind jedoch aufwendig und teuer in der Herstellung.

Beispielexample

Eine Meßvorrichtung weist folgenden Aufbau auf:
Auf die Wand eines Reaktionsbehälters 14 (Fig. 1, teilweise gezeigt) wird ein Grundflansch 2 montiert, der die Meßvorrichtung mit dem Reaktionsbehälter verbindet und den Meßraum 13 für die Nahinfrarot-Sonde 1 zugänglich macht. Die Sonde 1 ist über (nicht gezeichnete) Glasfaserkabel mit einem IR-Spektrometer verbunden. Die Nahinfratrot-Sonde 1 wird pneumatisch mit Hilfe von Druckluft über einen regelbaren Druckanschluß 6 in den Meßraum 13 gefahren. Die Druckluft bewirkt, daß der Kolben 8 mit dem Sondenschaft 9 sich in Richtung Meßraum bewegt. Der Meßkopf 10 befindet sich nun im Meßraum 13 und kann für die Messung genutzt werden. Ist der Meßvorgang beendet oder eine Reinigung des Meßkopfes 10 erforderlich, so wird der Druckluftanschluß 6 geschlossen und der Druckluftanschluß 7 geöffnet. Der Kolben 8 mit dem Sondenschaft 9 und dem Meßkopf 10 bewegt sich nun aus dem Meßraum 13 (Fig. 2) in die Sondenkammer 3. Der Meßkopf 10 kann nun durch Öffnung des Spülmitteleinlasses 11 und des Spülmittelauslasses 12 gereinigt werden.A measuring device has the following structure:
A base flange 2 is mounted on the wall of a reaction container 14 ( FIG. 1, partially shown), which connects the measuring device to the reaction container and makes the measuring space 13 accessible to the near-infrared probe 1 . The probe 1 is connected to an IR spectrometer via glass fiber cables (not shown). The near-infrared probe 1 is moved pneumatically with the aid of compressed air into the measuring space 13 via a controllable pressure connection 6 . The compressed air causes the piston 8 with the probe shaft 9 to move in the direction of the measuring space. The measuring head 10 is now in the measuring space 13 and can be used for the measurement. If the measuring process is finished or cleaning of the measuring head 10 is required, the compressed air connection 6 is closed and the compressed air connection 7 is opened. The piston 8 with the probe shaft 9 and the measuring head 10 now moves from the measuring space 13 ( FIG. 2) into the probe chamber 3 . The measuring head 10 can now be cleaned by opening the flushing agent inlet 11 and the flushing agent outlet 12 .

Anschließend kann der Meßkopf 10 im Bereich der Spülmittelkammer 4 mit einer Referenzlösung gefüllt werden, so daß eine Kalibrierung der Sonde 1 möglich ist. Ringförmige Dichtungen 15 zwischen Sondenschaft 9 und Sondenkammer 3 sorgen dafür, daß keine Spüllösung in den Reaktionsbehälter 14 gelangt und gleichzeitig kein Produkt aus dem Reaktionsbehälter 14 austritt.Subsequently, the measuring head 10 in the area of the detergent chamber 4 can be filled with a reference solution, so that a calibration of the probe 1 is possible. Annular seals 15 between probe shaft 9 and probe chamber 3 ensure that no rinsing solution gets into the reaction container 14 and at the same time no product emerges from the reaction container 14 .
