Abstract

A device for measuring temp. in pipelines consists of a pipe element provided with screwed connections to which a pipe stub is attached at right angles. A temp. sensor is located in this pipe stub and projects into the interior of the pipeline. The sensor is sealed by a plug (4) made of an elastic, non-porous, non-toxic, low heat conductivity and temp. resistant material and is pressed into the pipe stub (3). The surface (8) of this plug which corresponds to the inner surface of the pipe (1) is given the same shape as the pipe wall and has a polished finish. A central boring (5) in the plug corresponds to the dia. of the temp. sensor (6), and the sensor is fitted in this boring by a pressing operation. The plug is pref. made of polytetrafluoroethylene. USE/ADVANTAGE - Used for measuring the temp. in pipes carrying liquid, semi-liquid.

Description

Die Erfindung betrifft eine Vorrichtung zur Messen von Temperaturen in Rohrleitungen, in denen flüssige, pastenförmige oder gasförmige Nahrungsmittel, pharmazeutische Erzeugnisse und deren Vor- und Zwischenprodukte transportiert werden, bestehend aus einem mit Verschraubungen versehenen Rohrstück, an das senkrecht zur Rohrachse ein Stutzen angebracht ist, in dem sich ein mit Anschlußarmaturen versehener Temperatursensor befindet, der in das Rohrinnere hineinragt und innerhalb des Stutzens gegen den Rohrinhalt abgedichtet ist.The invention relates to a device for measuring Temperatures in pipelines in which liquid, pasty or gaseous foods, pharmaceutical products and their preliminary and Intermediates are transported consisting of a piece of pipe with fittings to which a nozzle is attached perpendicular to the pipe axis, in which there is a connection fitting Temperature sensor located in the inside of the pipe protrudes and within the nozzle against the Pipe content is sealed.

Beim Transport von Nahrungsmitteln, pharmazeutischen Erzeugnissen und deren Vor- und Zwischenprodukte in Rohrleitungen ist es meist erforderlich, schnelle und genaue Temperaturmessungen in diesen Produkten vorzunehmen. Dazu benutzt man Temperatursensoren, meist Widerstandsthermometer oder Thermoelemente, die von außen in die Rohrleitung eingebracht werden, normalerweise über einen angeschweißten Stutzen, in dem der Temperatursensor befestigt ist. Der Innenraum des Stutzens ist mit einer Dichtung versehen, um ein Austritt des Rohrleitungsinhalts nach außen zu verhindern. Bei Nahrungsmitteln und pharmazeutischen Erzeugnissen ist es außerordentlich wichtig, daß die Rohrleitungen glatt sind, damit sich keine Bakterien und andere Keime ansiedeln können. When transporting food, pharmaceutical Products and their preliminary and intermediate products in Pipelines are usually required to be fast and accurate temperature measurements in these products to make. For this you use temperature sensors, mostly resistance thermometers or thermocouples be introduced into the pipeline from outside, usually via a welded socket in which the temperature sensor is attached. The interior of the Stutzens is provided with a seal to a Exit of the pipeline contents to the outside prevent. For food and pharmaceutical It is extremely important for products that the Pipelines are smooth so there are no bacteria and can colonize other germs.  

Eine besondere Schwachstelle ist dabei die Einführungsstelle des Temperatursensors, da sich dort kleine Spalte an der Abdichtung nur schwer vermeiden lassen.A particular weak point is that Insertion point of the temperature sensor because there Avoid small gaps on the seal to let.

Es war daher Aufgabe der vorliegenden Erfindung eine Vorrichtung zur Messung von Temperaturen in Rohrleitungen zu entwickeln, in denen flüssige, pastenförmige oder gasförmige Nahrungsmittel, pharmazeutische Erzeugnisse und deren Vor- und Zwischenprodukte transportiert werden, bestehend aus einem mit Verschraubungen versehenen Rohrstück, an das senkrecht zur Rohrachse ein Stutzen angebracht ist, in dem sich ein mit Anschlußarmaturen versehener Temperatursensor befindet, der in das Rohrinnere hineinragt und innerhalb des Stutzens gegen den Rohrinhalt so abgedichtet ist, daß sich an der dem Transportrohr zugewandten Oberfläche keine Mikrospalte ausbilden, die als Ansatzstellen für Bakterienkolonien und andere Keime dienen könnten.It was therefore an object of the present invention Device for measuring temperatures in To develop pipelines in which liquid, pasty or gaseous foods, pharmaceutical products and their preliminary and Intermediates are transported consisting of a piece of pipe with fittings to which a nozzle is attached perpendicular to the pipe axis, in which is equipped with connection fittings Temperature sensor located in the inside of the pipe protrudes and within the nozzle against the Tube content is sealed so that the Surface facing the transport pipe no micro-gaps train that as starting points for bacterial colonies and other germs could serve.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Abdichtung aus einem Stopfen aus einem elastischen, porenfreien, nichttoxischen, schlecht wärmeleitenden und temperaturbeständigen Material besteht, der in Preßpassung an der Innenwand des Stutzens dicht anliegt, auf der dem Rohr zugewandten Oberfläche entsprechend der Form der Rohrwandung ausgebildet und geglättet ist, und zentral eine dem Durchmesser des Temperatursensors angepaßte Durchbohrung aufweist, in der der Temperatursensor mittels einer Preßpassung befestigt ist. This object is achieved in that the seal from a stopper from a elastic, non-porous, non-toxic, bad heat conductive and temperature resistant material consists of the press fit on the inner wall of the Stocks tightly, on the pipe facing Surface according to the shape of the pipe wall is trained and smoothed, and a central one Adjusted diameter of the temperature sensor Has perforation in the temperature sensor is attached by means of a press fit.  

Als Stopfenmaterial kommen vor allem Kunststoffe zur Anwendung, vorzugsweise Polytetrafluorethylen, das alle geforderten Eigenschaften in optimalen Umfang besitzt.Plastics are the main stopper material Application, preferably polytetrafluoroethylene, the all required properties to an optimal extent owns.

Mit dieser Vorrichtung ist es möglich, genaue Temperaturmessungen in Rohrleitungen durchzuführen, ohne daß sich Bakterien und andere Keime an der Meßstelle festsetzen können.With this device it is possible to get accurate Carry out temperature measurements in pipelines, without bacteria and other germs on the Can set measuring point.

Die Abbildung zeigt schematisch eine beispielhafte Ausführungsform der erfindungsgemäßen Vorrichtung im Längsschnitt. Sie besteht aus einem Rohrstück (1), das beidseitig mit Verschraubungen (2) versehen ist und so in die Rohrleitung, in der die zu messende Medien transportiert werden, eingefügt werden kann. Senkrecht zur Rohrachse ist ein Stutzen (3) angebracht, vorzugsweise angeschweißt, der eine Öffnung zum Rohrstück (1) aufweist, die mit einem Stopfen (4) gegen den Rohrinhalt abgedichtet ist. Dieser Stopfen (4) besitzt eine zentrale Bohrung (5), in die der Temperatursensor (6) eingepreßt ist, der in das Rohrinnere hineinragt und mit Anschlußarmaturen (7) versehen ist. Der Stopfen (4) ist so geformt, daß er gegen die Innenwand des Stutzens (3) angepreßt wird. Gleichzeitig ist die Durchbohrung (5) dem Durchmesser des Temperatursensors (6) so angepaßt, daß auch hier eine Preßpassung vorliegt. Die dem Rohrstück (1) zugewandte Oberfläche (8) des Stopfens (4) ist entsprechend der Rundung des Rohrstücks (1) geformt und sorgfältig geglättet, so daß sich keine Bakterien und andere Keime absetzen und vermehren können.The figure schematically shows an exemplary embodiment of the device according to the invention in longitudinal section. It consists of a pipe section ( 1 ), which is provided with screw connections ( 2 ) on both sides and can thus be inserted into the pipeline in which the media to be measured are transported. A pipe ( 3 ) is attached, preferably welded, perpendicular to the pipe axis and has an opening to the pipe section ( 1 ), which is sealed with a plug ( 4 ) against the pipe contents. This plug ( 4 ) has a central bore ( 5 ) into which the temperature sensor ( 6 ) is pressed, which protrudes into the interior of the pipe and is provided with connection fittings ( 7 ). The plug ( 4 ) is shaped so that it is pressed against the inner wall of the nozzle ( 3 ). At the same time, the through-hole ( 5 ) is adapted to the diameter of the temperature sensor ( 6 ) in such a way that an interference fit is also present here. The the tubular piece (1) facing surface (8) of the stopper (4) is shaped according to the curvature of the pipe piece (1) and carefully smoothed so that no bacteria and other germs can settle and proliferate.
