B - Anschlussart

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.

Product information "Pipe contact probe with housing"

Pipe contact probes are used for temperature measurement on pipelines. They can be easily fastened and fixed there with the supplied quick-release strap. The temperature is measured via the aluminum contact block on the underside of the probe. The robust connection housing offers best protection against humidity (IP65).

Qualification measurement series to ensure the function of our temperature probes over their service life

Qualifizierungsmessreihe Robust even with temperature changes Temperature probes are exposed to harsh environmental conditions, such as changing temperatures and humidity, and should still work reliably in the field for 15 years or more. Checkmark
Qualifizierungsmessreihe Resistant to heat and humidity Extremely varying ambient conditions cause immense stress for the temperature probe and the design must be suitably robust and qualified.        
Qualifizierungsmessreihe Long-term stable in any weather Continuous exposure to sunlight, snow, fog, cold and ice shall not impair the function of the temperature probe and compliance with the specification.        
Qualifizierungsmessreihe Robust even under high vibration load Depending on the application, compressors and fans generate strong vibrations which are transmitted to components and cables. Therefore the used temperature probes have to be vibration resistant (20g). Checkmark
Qualifizierungsmessreihe Reliable in practice: high pull-out force The robust design ensures the necessary cable pull-out resistance, even under vibration and higher temperatures. Checkmark
Qualifizierungsmessreihe Efficient through short response time Depending on the application, short response times may be necessary to ensure efficient control of the system. Our sensor design is optimised for this requirement and we prove response times.        
Qualifizierungsmessreihe Corrosion-resistant even in salt spray Temperature probes are also used in coastal regions. For this reason, the temperature probes must also be able to withstand salty air for a lifespan of 15 years.
