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.

Jeder Fühler benötigt eine Mindest-Eintauchtiefe, um die Temperatur des zu messenden Mediums annehmen und korrekt messen zu können. Faustformel: optimalerweise sollte die Eintauchtiefe 10-mal dem Schutzhülsendurchmesser entsprechen, mindest sollte jedoch ein 5-facher Wert verwendet werden.

Immersion probe with head - Important assembly advices

Measurement 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 deeply as possible in the medium to be measured during installation. The optimum installation depth should be 10-15 times the Ø of the protection sleeve or, when using an immersion sleeve, the Ø of the immersion sleeve. When installing in pipelines whose Ø does not have a sufficiently deep installation depth, you should install the probe either at an angle or in a pipe elbow. Make sure that there is sufficient space for the probe to be removed. 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 means of compression fitting: Please tighten the union nut of the compression fitting by hand as far as it will go (clearly noticeable). With a wrench suitable for the width across flats, please make a 1/4 turn on compression fittings with PTFE thrust collar. These compression fittings can be used several times in this way. In the case of compression fittings with stainless steel cutting ring, the compression fitting connects to the protection tube. This connection is pressure resistant up to 40 bar. However, the compression fitting can only be used once. It must also be tightened more firmly. Please tighten it with 1 3/4 turns.

Mounting by means of mounting flange: Please make sure that the Ø of the mounting flange matches the Ø of the protection sleeve. For B-head fittings with very long protection sleeves, we recommend a stainless steel or aluminum mounting flange due to its stability.

Mounting by using an immersion sleeve (4): Please note that the Ø and the length of the immersion sleeve must be selected to match the installation situation so that the minimum immersion depth can be achieved. Since 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 in such a way that the protection sleeve touches the bottom of the immersion sleeve and that the air cushion around the protection sleeve is as small as possible. The use of thermal paste can improve the response times.

Please lay the cable with reserve loop (5) and in such a way that no water can penetrate the sensor head. This allows you to extend the probe without disconnecting the electrical connection.

 

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.        
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.
