Bei Zwei-Leiter-Schaltungen addiert sich der Eigenwiderstand der Anschlussleitung zum Widerstandswert des Messwiderstands (Thermistor oder Pt) und verfälscht somit das Messergebnis. Ist der Widerstandswert des Messwiderstands groß gegenüber dem Eigenwiderstand der Anschlussleitung, so kann dieser Eigenwiderstand vernachlässigt werden. Bei Messwiderständen mit geringerem Widerstandswert (z.B. PT100), kann der Leitungseigenwiderstand die Messgenauigkeit jedoch signifikant verringern. Aus diesem Grund empfehlen wir die Zwei-Leiter-Technik in Verbindung mit kleinohmigen Messwiderständen nur dann, wenn Sie vergleichsweise kurze Anschlussleitungen, also kleinohmige Anschlussleitungen, verwenden können.

Für Applikationen, die eine sehr genaue Temperaturmessung erfordern, empfehlen wir Ihnen eine Drei- oder sogar Vier-Leiterschaltung zu verwenden.

Bei der Dreileiter-Schaltung wird der Leitungswiderstand jeder der drei angeschlossenen Leitungen mit Hilfe der dritten angeschlossenen Leitung ermittelt (alle Anschlussdrähte müssen exakt gleich lang sein) und anschließend vom gemessenen Gesamtwiderstand (Messwiderstand+Leitungswiderstand) abgezogen werden, so dass effektiv nur der Widerstandswert des Messwiderstands für die Temperaturbestimmung verwendet wird. Diese Subtraktion kann beispielsweise in der Messelelektronik automatisch durchgeführt werden.

Die sicherste und genaueste Messung erreichen Sie mit Hilfe einer Vierleiter-Schaltung. Hier wird auf jeder Seite des Messwiderstands eine zusätzliche Leitung angeschlossen. Zwei Leitungen dienen der Spannungsversorgung, die zwei anderen werden verwendet, um den Leitungswiderstand (ggf. auch asymmetrisch, also auch bei unterschiedlich langen Anschlussdrähtchen) zu ermitteln und vom Messwiderstandswert abzuziehen. Diese Subtraktion kann beispielsweise in der Messelelektronik automatisch durchgeführt werden.

Screw-in probe with housing - Important assembly advices

Measuring errors can occur due to heat dissipation to the environment. To keep these as small as possible, we recommend immersing the protection sleeve of your temperature probe as deep as possible into the medium to be measured during installation. The optimum installation depth should be 10-15 times the Ø of the protection sleeve or, if an immersion sleeve is used, the Ø of the immersion sleeve. When installing in pipes whose Ø does not have a sufficiently deep installation depth, you should either install the probe at an angle or in a pipe elbow. Make sure that you have enough space so that the probe can be removed again. 1) Installation with sufficient installation depth 2) Installation at an angle with small pipe Ø 3) Not like this: Minimum installation depth not reached

Installation by using an immersion sleeve (4): Please ensure that the Ø and length of the immersion sleeve are selected to suit the installation situation so that the minimum immersion depth can be achieved. Please also ensure that the process connection is correct. Because the probe is not inserted directly into the medium, but via the immersion sleeve, the response times are somewhat slower. The probe should be selected so that the protection sleeve touches the bottom of the immersion sleeve and the air cushion around the protection tube is as small as possible. The use of thermal conduction paste can improve the response times.

Please lay the cable so that no water can penetrate the probe and with a spare loop (4). This allows you to extend the probe without disconnecting the electrical connection.
