Description

«Anordnung eines Thermistors in einem Temperaturmesselement" Die Erfindung betrifft eine Anordnung eInes Thermistors in einem Temperaturmesselement, insbesondere in einer Schraub= kapsel eines Temperaturwächters."Arrangement of a thermistor in a temperature measuring element" The invention relates to an arrangement of a thermistor in a temperature measuring element, in particular in a screw cap of a temperature monitor.

Temperaturmesselemente mit in eine Schraubkapsel eingebautem Thermistor sind bekannt (DT-Gbm 6 919 523), ifier sind die Thermistoren isoliert, d.h. mit Kunststoff umgossen, in den Fühler eingelegt, so daß mit der metallischen Umhüllung keine direkte Verbindung besteht. Da der Kunststoff eine Wärmedamnung darstellt, ist die Folge, daß ein derartiges Temperaturmess element eine große Anzeigeträgheit besitzt. Diese zu beseitigen ist Aufgabe der Erfindung.Temperature measuring elements with a thermistor built into a screw cap are known (DT-Gbm 6 919 523), ifier the thermistors are isolated, i.e. with Plastic encased, inserted into the sensor, so that with the metallic casing there is no direct connection. Since the plastic is a thermal insulation, is the consequence that such a temperature measuring element has a large display inertia owns. The object of the invention is to eliminate these.

Die Lösung dieser Aufgabe erfolgt erfindungsgemäß dadurch, daß der in bekannter Weise im Innern eines bolzenförmigen An= satzes der Schraubenkapsel angeordnete Thermistor mit einem Pol am Boden des Ansatzes verlötet ist.This object is achieved according to the invention in that the in a known manner in the interior of a bolt-shaped shoulder of the screw capsule arranged thermistor is soldered to one pole at the bottom of the approach.

Um die galvanische Verbindung mit dem Gewindeteil der Schraub= kapsel aufzuheben, kann der bolzenförmige Ansatz mit dem Thermistor vor dem Gewindeteil isoliert sein. Der Wärmekontakt mit dem zu messenden Medium wird noch in vorteilhafter Weise erhöht, wenn der Thermistor zusätzlich mit einer gut wärme= leitenden isolierenden Masse umgeben ist.To make the galvanic connection with the threaded part of the screw cap to cancel, the bolt-shaped approach with the thermistor in front of the threaded part be isolated. The thermal contact with the medium to be measured is even more advantageous Way increases if the thermistor is additionally provided with a good heat = conductive insulating Earth is surrounded.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt.An embodiment of the invention is shown in the drawing.

Das Temperaturmesselement ist eine Schraubkapsel mit einem <bwindeteil 1 und daran angeordnetem bolzenförmigen Ansatz 2, auf dessen Boden 5 ein Thermistor 3 gelegt und zur Kontakt= gabe mit einem Pol 4 verlötet ist. Mit dem zweiten Pol 6 ist ein Leiter 7 fest verbunden.The temperature measuring element is a screw cap with a winch part 1 and arranged thereon bolt-shaped extension 2, on the bottom 5 of a thermistor 3 and is soldered to a pole 4 for contact = giving. With the second pole 6, a conductor 7 is firmly connected.

Um den Thermistor 3 von dem Gewindeteil 1 der Schraubkapsel galvanisch zu trennen, ist in dem bolzenförmigen Ansatz 2 ein Isolierteil s eingesetzt. Die isolierende Trennstelle kann selbstverständlichzåuch an anderen Stellen der Schraubkapsel vorgesehen sein. Die elektrische Verbindung mit dem festgelöteten Pol erfolgt mittels einem Leiter 9. Die Leiter 7 und 9 sind an eine nicht dargestellte Steckvorrichtung im Gewindeteil der Schraubkapsel geführt. Der Wärmekontakt mit dem zu messen den Stoff kann noch verbessert werden, indem der Thermistor zusätzlich mit einer gut wärmeleitenden isolierenden Masse 1o umgossen ist.To the thermistor 3 from the threaded part 1 of the screw cap galvanically to separate, an insulating part s is used in the bolt-shaped extension 2. the The insulating separation point can of course also be used at other points on the screw cap be provided. The electrical connection to the soldered pole is made by means of a conductor 9. The conductors 7 and 9 are connected to a connector, not shown guided in the threaded part of the screw cap. The thermal contact with the one to be measured Fabric can still be improved by adding the thermistor with a well thermally conductive insulating mass 1o is encapsulated.
