Bezugs- oder Ablei"celektrode für PotentialmessungenReference or lead electrode for potential measurements

Die vorliegende Erfindung betrifft Bezugs- und Ableitelektroden für Potentialmessungen mittels Messketten, die sich bei verschiedenen Temperaturen einsetzen lassen.The present invention relates to reference and lead electrodes for potential measurements by means of measuring chains, which can be used at different temperatures.

Bei der Verwendung von Messketton für Potentialmessungen, z.B. pH-Messungen, bei verschiedenen Temperaturen ist bekanntlich der Faktor K (T) der Nernst'sehen Gleichung, auch Nernst-Faktor genannt, zu berücksichtigen.When using a measuring chain for potential measurements, e.g. pH measurements, at different temperatures is known to be the factor K (T) of Nernst's vision Equation, also known as the Nernst factor, must be taken into account.

Vorrichtungen zur Berücksichtigung dieses Faktors wurden bereits von R.G.Bates, in "Electromatic pH Determinations" [New York 1954] sowie K. Schwabe, in "pH-Messtechnik" 3. Auflage [Dresden und Leipzig 1963] beschrieben. Bei industriellen pH-Messungen erfolgt die entsprechende Korrektur der Messergebnisse selbsttätig mittels Widerstandsthermometern, die sich auf Messtemperatur befinden und gesondert von Bezugs- und Ableitelektrode in das Messgut eintauchen.Devices for taking this factor into account have already been described by RGBates, in "Electromatic pH Determinations" [New York 1954] and by K. Schwabe, in "pH-Messtechnik" 3rd edition [Dresden and Leipzig 1963]. In industrial pH measurements, the corresponding correction of the measurement results is performed automatically by means of resistance thermometers which are located on the measuring temperature and separate from reference and reference electrode immersed in the material to be measured.

Es wurde nun gefunden, dass sich wesentliche Vorteile ergeben, wenn man die Temperaturmessvorrichtung mit der Elektrode kombiniert.It has now been found that there are significant advantages when using the temperature measuring device combined with the electrode.

Gegenstand vorliegender Erfindung ist daher eine Bezugs- oder Ableitelektrode, gekennzeichnet durch ein eingebautes elektrisches Widerstandsthermometer oder ein- > } gebauten Thermistor. Mit "Widerstandsthermometer" werden in diesem Zusammenhang nicht nur Widerstandsthermometer allgemein gängiger Art, sondern auch beliebige andere Elemente mit geeignetem Temperaturkoeffizienten bezeichnet.Accordingly, the present invention is therefore a reference or discharge electrode, characterized by a built-in electric resistance thermometer or mono->} assembled thermistor. "Resistance thermometers" are used in this context to denote not only resistance thermometers of the generally common type, but also any other elements with suitable temperature coefficients.

den Vorteil, dass die Temperatur genau an der Stelle gemessen wird, an der sie für die Kompensation von Bedeutung ist. Von Vorteil ist ferner die geringere Raumbeanspruchung des kombinierten Elementes gegenüber den bisherigen Einzelelementen, Elektrode und Temperaturmessvorrichtung, was bei der industriellen Anwendung eine erhebliche Rolle spielt. Das kombinierte Element kann wesentlich bruchsicherer gestaltet werden als zwei Einzelelemente. ■Die Herstellung der erfindungsgemässen Elektroden ist, wie raus vorstehender Beschreibung hervorgeht, äusserst einfach, -V=und bietet erhebliche wirtschaftliche Vorteile gegenüberthe advantage that the temperature is measured precisely at the point where it is important for compensation. Another advantage is the lower space requirement of the combined element compared to the previous individual elements, electrode and temperature measuring device, which plays a significant role in industrial use. The combined element can be made much more shatterproof than two individual elements. As can be seen from the above description, the production of the electrodes according to the invention is extremely simple, -V = and offers considerable economic advantages over this
