57	Abstract	AB	Die erfindungsgemäße Vorrichtung zur Druckmessung ermöglicht eine berührungslose Messung des Druckes in einem Druckaufschlußgefäß für thermische und mikrowellenbeheizte chemische Reaktionen. Dabei wird der bei der chemischen Reaktion in dem Druckbehälter des Druckaufschlußgefäßes entstehende Innendruck auf ein mit dem Druckbehälter kräftemäßig gekoppelten Sensorelement übertragen. Die durch den Druck hervorgerufene spannungsinduzierte Doppelbrechung des Sensorelements wird benutzt, die Polarisation eines das Sensorelement durchstrahlenden polarisierten Lichtstrahles zu verändern, so daß aus der Veränderung der Polarisation Rückschlüsse auf den Innendruck des Druckbehälters gemacht werden können.
