Description
Die Erfindung betrifft eine Messeinrichtung zur telemetrischen Auswertung eines einen elektrischen Schwingkreis aufweisenden passiven Sensors, sowie ein Messsystem mit einer Messeinrichtung und einen passiven Sensor.The The invention relates to a measuring device for telemetric evaluation of an electrical oscillating circuit having passive sensor, as well as a measuring system with a measuring device and a passive one Sensor.
Stand der TechnikState of the art
Es ist bekannt, für die Erfassung von physikalischen Meßgrößen wie Druck, Feuchtigkeit oder Temperatur Sensoren zu verwenden, die einen elektrischen LC-Schwingkreis aufweisen. Die Wandelung der physikalischen Messgröße in ein elektrisch auswertbares Messsignal basiert hier auf der Abhängigkeit der Resonanzfrequenz und/oder der Güte des LC-Schwingkreises von der Messgröße. Die Verschiebung der Resonanzfrequenz und/oder Güte des Schwingkreises kann sowohl durch die Änderung der Kapazität als auch durch die Änderung der Induktivität bewirkt werden. Eine Messeinrichtung ermittelt die Resonanzfrequenz und/oder Güte des Schwingkreises des Sensors. Die Messeinrichtung kann zu diesem Zweck sowohl galvanisch als auch telemetrisch mit dem Sensor verbunden sein. Eine telemetrische Auswertung des Sensors ist vorteilhaft, wenn eine galvanische Kopplung des Sensors an die Messeinrichtung nicht oder nur schwer möglich ist. Eine exakte telemetrische Auswertung von Resonanzfrequenzen und/oder Güte eines Schwingkreises des Sensors ist üblicherweise mit hohem technischem Aufwand verbunden, beispielsweise unter Einsatz eines Netzwerkanalysators.It is known for the acquisition of physical quantities like pressure, humidity or temperature sensors that use have an electrical LC resonant circuit. The change of the physical measurand in an electrically evaluable Measurement signal is based here on the dependence of the resonance frequency and / or the quality of the LC resonant circuit of the measured variable. The shift of the resonance frequency and / or quality of the resonant circuit can be changed both by capacity also caused by the change in inductance become. A measuring device determines the resonance frequency and / or Quality of the resonant circuit of the sensor. The measuring device can for this purpose both galvanic and telemetric with be connected to the sensor. A telemetric evaluation of the sensor is advantageous if a galvanic coupling of the sensor to the Measuring device is not possible or difficult. An exact one telemetric evaluation of resonance frequencies and / or quality a resonant circuit of the sensor is usually with connected high technical effort, for example, using a network analyzer.
