“…Die FE-Analyse zeigt weiterhin, dass eine Erweiterung des Linearitätsbereichs der Sensorkennlinie für die gegebene Sensorgeometrie nur über den Einsatz eines Rohres mit höherer Wärmeleitfähig-keit erzielt werden kann. Für das Stahlrohr kann eine Erweiterung des Linearitätsbereichs nur durch eine Verringerung des Rohrdurchmessers erreicht werden [6]. …”

Gestützt auf eine Finite-Elemente-Analyse wurde ein kalorimetrischer Strömungssensor in Dickschichttechnik auf einem Stahlrohr aufgebaut. Die Sensorkennlinie wurde sowohl experimentell als auch aufgrund der numerischen Simulation ermittelt. Die erforderlichen Maßnahmen zur Erweiterung des linearen Kennlinienbereichs und zur Erhöhung des Signalpegels werden aufgezeigt. Schlagwörter: Strömungssensor, Dickschichttechnik, Rundsiebdruck Development and Characterization of a Calorimetric Flow Sensor Realized in Thick-Film TechnologyBased on the results of Finite Element Analyses a calorimetric flow-sensor has been realized on a steel tube by thick-film technology. The sensor characteristics have been determined experimentally as well as by numerical simulation. The paper discusses procedures required to increase the linearity range of the sensor characteristic and sensor signal output.

“…This provides small and compact dimensions of the complete set-up. On an austenitic stainless steel tube (inner diameter of 2 mm, outer diameter of 4 mm, length 120 mm), the heating element of a total length of 80 mm was developed in a way similar to that described in [3]. The maximum peak temperature on the surface of the heating tube was 600 °C and it is obtained within 5 seconds with heating power of 28 W. It is also possible to reach higher temperatures, but this is restricted with working temperatures of glues which connect thermocouples for the tube.…”

The possible solution for bonding two different materials with intermediate layer of adhesive at relatively low temperatures in the micro domain is proposed in this paper. A stream of hot gas has been used for melting and softening different kinds of adhesives. After cooling down at room temperature, adhesives harden forming a stabile and strong bond. The gas is heated as it passes through the tube with the heater developed on it. The parameters which induce the heat transfer and the process performance generally are considered through various experiments and by numerical simulations. Some advantages of this process are applicability for different material combinations, cost and time efficiency, compact size of equipment etc.
