B. with Bourdon tube 02 is a closed tube with an oval cross-section that is curved in a crescent shape. Or a Bourdon tube with the same measurement properties, which is particularly characterized in that it is coupled by a pressure sensor 07 attached directly to the Bourdon tube, which in turn directly transmits the change in pressure due to the change in resistance to the system electronics 08. The values calculated here can be displayed in bar psi or another known measured value.
Description
Zusammenfassung: Ein Manometer z. B. mit Bourdonfeder ist eine geschlossene Röhre mit ovalem Querschnitt, die halbmondförmig gebogen ist. Der einwirkende Druck biegt diese Form auf, da der Druck bestrebt ist, den Querschnitt der Röhre in Kreisform zu bringen. Die Größen dieser Bewegungen werden durch die auftretenden Kräfte an der Bourdonfeder mittels direkt auf der Bourdonfeder aufgebrachten Folien-Drucksensoren übertragen und in der Manometerelektronik ausgewertet und weiterverarbeitet. Hierbei wird der jeweilige Manometerdruck durch eine LCD-Anzeige angezeigt. Des Weiteren wurde ein im Manometer träger eingesetzter Temperatursensor mit der Manometerelektronik verbunden, wobei diese Temperaturwerte ebenfalls auf dem LCD-Display aber auch extern weiter verarbeitet werden kann.Summary: A manometer z. B. with Bourdon spring is a closed tube with an oval cross-section, which is bent crescent-shaped. The applied pressure bends this shape as the pressure tends to circularize the cross section of the tube. The sizes of these movements are transmitted by the forces occurring on the Bourdon spring by means of directly applied to the Bourdon spring film pressure sensors and evaluated in the pressure gauge electronics and further processed. In this case, the respective pressure gauge is indicated by an LCD display. Furthermore, a temperature sensor inserted in the manometer was connected to the pressure gauge electronics, whereby these temperature values can also be further processed externally on the LCD display.
Beschreibungdescription
Die Erfindung bezieht sich auf ein Manometer, dass verschiedene Messwert anzeigen zur Verfügung stellt.The invention relates to a pressure gauge that provides various reading readings.
Messungen von Drücken sind in zahlreichen Bereichen unabdingbar. Da verschiedene Messwerte und Zustände wie z. B. in der Industrie zur Anlagentechnik unabdingbar sind, werden diese meist zur Weiterverarbeitung in den Anlagen aus Steuerungszwecken oder Zustandsanzeigen benötigt und eventuell ausgewertet. Die Umsetzung, mechanischen Bewegungen in Elektronischen Impulsen und gleichzeitiger Temperaturerfassung ist daher von hoher technischer Bedeutung. Es ist bekannt, dass es elektronische Manometer gibt die mit Widerständen, vorzugsweise aufgebracht auf einem Zungen förmigen elastischen Biegeabschnitt, der über eine Koppelstange direkt zur Kraftübertragung mit der Bourdonfeder verbunden ist. Des weiteren sind elektronische Manometer bekannt, die mit in einem Rohr befindlichen Drucksensor direkt mit dem Medium beaufschlagt werden.Measurements of pressures are indispensable in many areas. Since different measured values and states such. B. are indispensable in the industry for systems engineering, they are usually needed for further processing in the systems for control purposes or status indicators and possibly evaluated. The implementation, mechanical movements in electronic pulses and simultaneous temperature detection is therefore of great technical importance. It is known that there are electronic pressure gauges equipped with resistors, preferably applied to a tongue-shaped elastic bending section, which is connected via a coupling rod directly to the power transmission with the Bourdon spring. Furthermore, electronic pressure gauges are known which are acted upon directly in the medium with a pressure sensor located in a tube.
Erfindungsgemäß wird das elektronische Manometer mit einem drucksensibel Druckensor ausgestattet, der direkt auf einwirkende Drücke seinen Widerstand in Normalrichtung aufgebrachtem Druck ändert. dieser Drucksensor wird direkt auf der Bourdonfeder mittels elastischem Verbundkleber aufgeklebt. Durch die zwangsweise auftretenden Kräfte in der Bourdonfeder wird der Drucksensor mit Druck beaufschlagt so dass der Drucksensor seine Widerstandsgröße verändert, dieser Drucksensor ist wiederum mit einer Anlagenelektronik verbunden auf der die gesamte Elektronik zur Steuerung und Weiterverarbeitungen der einzelnen Elektronikbauteile sind.According to the invention, the electronic pressure gauge is equipped with a pressure-sensitive pressure sensor which changes its resistance applied in the normal direction directly to acting pressures. This pressure sensor is glued directly to the Bourdon spring by means of elastic composite adhesive. Due to the forcibly occurring forces in the Bourdon spring the pressure sensor is pressurized so that the pressure sensor changes its resistance, this pressure sensor is in turn connected to a system electronics on which the entire electronics for controlling and further processing of the individual electronic components.
Um den aufgebrachten Drucksensor vor mechanischen und Umwelteinflüssen zu schützen, wird die gesamte Bourdonfeder inkl. den darauf befindlichen Drucksensor mit einer dauerelastischen auf Silicon basierende Beschichtung versiegelt.To protect the applied pressure sensor against mechanical and environmental influences, the entire Bourdon spring, including the pressure sensor located on it, is sealed with a permanently elastic silicone-based coating.
Zur Darstellung der ermittelten Werte wird ein herkömmliches LCD-Display eingesetzt, dass wiederum über die Manometerelektronik betrieben wird.To display the values determined, a conventional LCD display is used, which in turn is operated via the pressure gauge electronics.
Im Manometerkörper wurde ein Tauchrohr mit Gewinde eingebaut. Dieses Tauchrohr dient zur Aufnahme des Temperatursensors um unmittelbar die Temperatur vom zu messenden Medium zu erfassen. Der Temperatursensor ist mit der Elektronik des Manometers gekoppelt um die Temperaturwerte weiter zu verarbeiten und z. B. der Systemsteuerung bereitzustellen.In the manometer body, a dip tube with thread was installed. This dip tube is used to hold the temperature sensor to directly detect the temperature of the medium to be measured. The temperature sensor is coupled to the electronics of the manometer to further process the temperature values and z. B. the control panel.
