摘要： A sensor arrangement for a film type anemometer which includes a carrier plate; a precision resistor; a planar, elongated heating resistor supplied with an adjustable power supply; and a retaining device. The operational temperature of the heating resistor is increased by a fixed predetermined differential amount versus the temperature determined by the precision resistor. The heating resistor has at least one resistive layer disposed on a substrate. The heating resistor is attached in a bridge-like fashion in a recess of the carrier plate. The retaining device has a low heat transfer and has two opposite attachment areas which retain respective ends of the heating resistor. Each of the attachment areas being directed towards respective ends of the heating resistor and each attachment area having at least a bearing surface, a lateral peripheral surface and a longitudinal peripheral surface which extends in the longitudinal direction of the heating resistor for receiving an end area of the heating resistor. At least one of the surfaces of the attachment areas is fastened in a mechanically stable fashion to an edge area of the heating resistor. The heating resistor is partially covered at least at one of its ends and on a top surface portion thereof in the attachment areas by a surface portion of the carrier plate.

摘要： In order to obtain a rapid response of resistor elements having a hot film in a sensor carrier of a hot film anemometer, the resistor elements are inserted into a drawer-like recess at one end of the sensor carrier. The resistor elements rest with one end on a three point contact and are held fast on the three point contact through tension by means of contact springs in the connection area of contact clamps. Heat transfer which is detrimental to exact measurements can be avoided by means of the three point contact.

摘要： An electrical temperature sensor has a platinum-containing resistance layer as a measuring resistor, which is applied on the electrically insulating surface of a ceramic substrate. For protection against contamination or damage, the resistance layer is provided on its side facing away from the ceramic substrate with an intermediate layer as a diffusion barrier layer. In a first embodiment, a platinum layer as an electrode is applied on the intermediate layer spaced from the resistance layer. The electrode protects the measuring resistance against platinum poisons, such as stray silicon ions, which could emerge, for example, from a passivation layer made of glass. In a second embodiment, the electrical temperature sensor is provided with a multiple layer, wherein a covering layer is applied on the intermediate layer as a passivation layer made of glass. Also in this embodiment, an electrode in the form of a platinum layer can be applied spaced from the resistance layer. The intermediate layer functioning as a diffusion barrier layer is made of a ceramic containing Al2O3, MgO or tantalum oxide. Furthermore, it is also possible to insert an intermediate layer made of a layer system with a series of layers of several oxides.

摘要： A temperature-dependent measuring resistance with rapid response time is at least partially arranged on an electrically insulating surface of a ceramic substrate, wherein a portion of the conductor path spans a recess situated in the substrate in a bridge-like manner, and the remaining portion of the conductor path in the edge area of the substrate adjacent to the recess is provided with connection contact fields. The conductor path comprises a platinum or gold layer, wherein the conductor path is partially provided with a cover layer of glass, and wherein the connection contact fields are exposed. In a further embodiment, the conductor path is arranged together with the connection contact fields either on a screen-printed glass membrane or on a thin film membrane applied in a PVD process, which covers the surface of the ceramic substrate and spans the recess. The cover layer is likewise selectively applied by screen printing in case there is a glass membrane. In the case of a thin film membrane, the cover layer is also applied selectively by a PVD process and can be the same material as the thin film membrane. The ceramic substrate preferably comprises aluminum oxide.

摘要： A process is provided for manufacturing a sensor arrangement for temperature measurement with a temperature-sensitive measuring resistance which has a thin, metal resistance layer electrically insulated toward the outside, and exposed contact surfaces on a ceramic substrate. The contact surfaces are connected electrically conducting and directly mechanically fast with high temperature-resistant conductor paths electrically insulated from one another on a ceramic carrier element. The measuring resistance is bonded and attached by application to and subsequent firing on a carrier element prepared prior to outfitting. A platinum-containing thick film conducting paste serves as a means for attachment and bonding. Contact surfaces for connecting a plug or cable are arranged at the end of the carrier element facing away from the measuring resistance. The temperature sensor, a standard component in the form of a flat measuring resistance, is applied to the ceramic carrier element without the use of wires as an SMD component. The sensor arrangement manufactured by the process is suited for temperature measurements even above 400° C. The process is economical in that it uses a few standardized individual component parts and easily automatable operation steps.

摘要： In a temperature sensor with a platinum resistance thermometer accommodated in a tube-shaped housing, the platinum resistance layer belonging thereto should be protected against pollution or contamination of the platinum, since the electrochemical characteristics of platinum can be reduced by substances in the surroundings in the event of too low a partial pressure of oxygen. For this purpose, a mechanically solid and liquid-impermeable, connection is provided in the connection region of the tube-shaped housing, which permits an admission of air-oxygen into the housing from the environment of the connecting cable. The air-oxygen admission is made possible through a liquid-impermeable oxygen-permeable jacket for the connecting cable and/or over an accompanying connecting plug, whereby the admission of air-oxygen takes place along a glass filament filler running parallel to the electrical leads inside the jacket of the connecting cable.
