Abstract
Description
Druck- und Temperatursensor mit einer Druckmesszelle, einer Signalverarbeitungselektronik und einem Anschlussteil mit elektrischen Kontakten für die Weiterleitung der elektrischen Signale.Print- and temperature sensor with a pressure measuring cell, a signal processing electronics and a connection part with electrical contacts for the transmission of electrical Signals.
In
der
Der Erfindung liegt das Problem zugrunde einen kombinierten Druck- und Temperatursensor zu schaffen, der in Normalmaßausführung und in sehr kleiner Bauformausführung möglich ist und dessen Signalverarbeitungselektronik direkt auf der Messzelle aufliegt und dessen Anschlussteil für die Weiterleitung der elektrischen Signale mittels eines elektrischen Kabels ausgestaltet ist.Of the Invention is based on the problem of a combined pressure and To provide temperature sensor, which is possible in normal dimension and in a very small design version and its signal processing electronics directly on the measuring cell rests and its connection part for the transmission of electrical Signals is designed by means of an electric cable.
Die erfindungsgemäße Gestaltung des Druck- und Temperatursensors ermöglicht eine materialeinsparende Herstellung des Sensors in den verschiedensten Baugrößen. Es wird ein zusätzlicher Schaltungsträger eingespart, da der Verformungskörper die Funktion des Schaltungsträgers übernimmt. Hierdurch wird eine Kostenoptimierung erzielt.The inventive design The pressure and temperature sensor enables a material-saving Production of the sensor in various sizes. It an additional circuit carrier is saved, because of the deformation body the function of the circuit board takes over. As a result, a cost optimization is achieved.
Vorteilhafte Ausgestaltungen der Erfindung sind in den Ansprüchen 2 bis 6 aufgeführt. Bei der Weiterbildung nach Anspruch 2 sind mehrere separate ASICs auf der Messzelle angeordnet. Hierdurch lassen sich komplizierte Signalverarbeitungen realisieren. Bei der Weiterbildung nach Anspruch 3 kann mittels der Signalverarbeitungselektronik über das Anschlusskabel ein verstärktes, kompensiertes und kalibriertes Ausgangssignal für Druck und Temperatur übertragen werden. Bei der Weiterbildung nach Anspruch 4 sind die Leiter des Anschlusskabels an ihrem Ende abgewinkelt. Diese Abwinkelung dient gleichzeitig als Lötstelle für das Anschlusskabel. Nach Anspruch 5 kann des freie Ende des Anschlusskabels gleich mit einem Steckerelement versehen sein, was eine standardgemäße elektrische Verbindung des Sensors mit weiteren Schaltungen, Geräten usw. ermöglicht. Bei der Weiterbildung nach Anspruch 6 ist der Zwischenraum zwischen dem Kopf der Messzelle und dem ASIC nicht verfüllt, um Drucksignalverfälschungen zu verhindern. Zum Zweck des Feuchteschutzes ist dieser Zwischenraum nur mit einem Silikongel oder Schutzlack schleuderbeschichtet.advantageous Embodiments of the invention are listed in claims 2 to 6. at The development according to claim 2, a plurality of separate ASICs arranged the measuring cell. This allows complicated signal processing realize. In the development according to claim 3 can by means of the signal processing electronics via the connection cable reinforced, compensated and calibrated output signal for pressure and temperature transfer become. In the development according to claim 4, the head of Connecting cable angled at its end. This bend serves simultaneously as a solder joint for the Connecting cable. According to claim 5, the free end of the connecting cable be provided with a male member, which is a standard electrical connection the sensor with other circuits, devices, etc. allows. In the development according to claim 6, the gap between the head of the measuring cell and the ASIC are not filled to Drucksignalverfälschungen to prevent. For the purpose of moisture protection is this gap only spin-coated with a silicone gel or protective varnish.
