Patent number: 11382182Abstract: A planar heating element comprising a PTC resistive structure, which is arranged in a defined surface region of a first surface of a support substrate. The electrical connection contacts for connection to an electrical voltage source are associated with the PTC resistive structure, wherein the PTC resistive structure—starting from the two electrical connection contacts—has at least one internal conductive trace and a parallel connected, external conductive trace. The internal conductive trace has a greater resistance than the external conductive trace and the resistances of the internal conductive trace and external conductive trace are so sized that upon applying a voltage an essentially uniform temperature distribution is present within the defined surface region.Type: GrantFiled: June 9, 2020Date of Patent: July 5, 2022Assignee: Innovative Sensor Technology IST AGInventors: Jiri Holoubek, Mirko Lehmann, Josef Vik

Patent number: 10809136Abstract: The present disclosure relates to a thin film sensor element for determining and/or monitoring temperature. For this purpose, a resistive structure is provided, which is arranged in a resistive region on a substrate. The resistive structure is so formed that a first section of the resistive structure branches at a first reference point into two branches, and that a second section of the resistive structure branches at a second reference point into two other branches. In a contact region, the four branches are connected with four intermediate conductors in four contact areas, which are insulated from one another. In this way, the thin film sensor element is a real four conductor sensor element, wherein the reference points of the four conductor circuit lie within the resistive region. The resistance thermometer with the thin film sensor element of the invention is distinguished by a high accuracy.Type: GrantFiled: April 12, 2017Date of Patent: October 20, 2020Assignee: Innovative Sensor Technology IST AGInventor: Jiri Holoubek
