Bitte prüfen Sie, welches Messelement (Thermistortyp oder Pt) für Ihre Anwendung der Passende ist. Wichtige Informationen zum Messelement entnehmen Sie bitte den Kennlinien und Datenblättern. Diese finden Sie in der Langbeschreibung oder in unserem Download-Bereich.
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.

Screw-in probes with M8x1 connector are used in process measurement technology and measure the temperature in cables or vessels in the range from -50 °C to +400 °C in gaseous or liquid media. The protection sleeve is made of stainless steel and can be inserted into the process permanently, pressure proof and vibration resistant with the M8x1 thread. A suitable connection cable can be found in the accessories.

Screw-in probe with connector - 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 you have sufficient 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 pay attention to the correct process connection. 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 conduction paste can improve the response times. | ||||||||||||||||||
