摘要:
Ein Längen- und Temperaturmeßgerät für Tankanlagen besitzt ein Meßrohr und eine das Meßrohr umgebende Nachführeinrichtung zum Nachführen eines im Meßrohr verschiebbaren Schiebers. Um eine genaue Füllstandsmessung und eine genaue Messung der mittleren Temperatur einfach und zuverlässig durchführen zu können, ist im Meßrohr (2) mindestens ein Widerstandselement (24) in Längsrichtung über die gesamte Meßstrecke angeordnet und besitzt aus dem Meßrohr (2) herausgeführte Endanschlüsse (28, 30). Am Schieber (20) befindet sich ein Schleifkontakt (30), der das Widerstandselement (24) abgreift. Eine Referenzspannungsquelle (40) liegt zwischen den Endanschlüssen (28, 30) des Widerstandselements (24), und es ist eine elektrische Meßeinrichtung (42) an den Schleifkontakt (30) zum Messen der abgegriffenen Teilspannung anschließbar.
摘要:
The present invention relates to a method and a device (1) for predicting an end temperature (46) of a temperature change affecting a temperature-sensitive system, such as a sensor system (2). The method comprises the steps of inputting at least one measured temperature value (11) into a first temperature prediction model (30) and into a second temperature prediction model (32), calculating a first predicted temperature (34) based on the first temperature prediction model (30), calculating a second predicted temperature (36) based on the second temperature prediction model (32), and calculating a final predicted temperature (18) from the first predicted temperature (34) and the second predicted temperature (36). The final predicted temperature (18) can be calculated before the end temperature (46) is measurable by a temperature sensor (10). Thereby, limitations caused by heat-transfer-related thermal inertia are mitigated and time delay is minimized. By combining the results of two temperature prediction models (30, 32) into the final predicted temperature (18), the inventive method further can achieve a higher accuracy than a method employing only one of the prediction models. The device (1) comprises means for performing the inventive method. Further, the present invention relates to a sensor system (2) comprising the device (1).
