Abstract

By mounting one or more auxiliary contacts on sensors, coding for the identification of the corresponding sensors is made possible. By means of the coded sensors, it is possible to connect the sensors provided with the same connectors to the measuring device and to impart to the measuring device and the measuring electronics the necessary information about the type, sensitivity limit and other information about the measuring electronics.

Description

Es ist bekannt, daß für die Erfassung verschiedener Meßgrößen verschiedene Sensorfamilien angeboten werden, die oft den gleichen Aufbau und die gleichen Anschlüsse aufweisen und sich nur in einigen Eigen­ schaften wie z. B. Grenzwerte, Empfindlichkeit oder Schnelligkeit unterscheiden. Beim Bau einheitlicher Meßgeräte, die alle von diesen Sensortypen gleich angeschlossen werden können, ist es notwendig, die entsprechend eingesteckten Sensoren automatisch zu erkennen und die Elektronik so zu steuern.It is known that for the detection of various Measured variables offered different sensor families that are often the same structure and the same Have connections and only some of them shafts such as B. limits, sensitivity or Differentiate speed. More uniform when building Measuring devices, all of these sensor types the same can be connected, it is necessary that correspondingly plugged in sensors automatically recognize and control the electronics.

Unsere Erfindung dient dazu, daß es ermöglicht wird, ohne die Aufbauweise oder die Kontakte zu verändern, die Sensoren zu codieren und durch die Elektronik die verschiedenen Sensortypen zu identifizieren. So kann es zum Beispiel bedeuten, daß bei chemischen Sensoren, die für ein bestimmtes Gas z. B. Kohlenmonoxid nach­ zuweisen sind, die Hilfskontakte Widerstandswerte zwischen 10 und 100 Ohm aufzeigen, wobei die Wider­ standswerte bestimmte Empfindlichkeitsbereiche bedeu­ ten. Das bedeutet, wenn die Sensoren in der Fassung eingesteckt sind und die Elektronik z. B. 50 Ohm Widerstand zwischen den Hilfskontakten abliest, daß nach der vorherigen Codierung der Sensor, ein Kohlen­ monoxidsensor, einen Meßbereich von z. B. 0-500 ppm aufweist. Durch diese Identifizierung kann die Elektronik entsprechende, vorher schon abgestimmte Informationswerte, die Herstellungsfaktoren, ein­ stellen, und so den Sensor richtig identifizieren und die entsprechenden Meßwerte in Anzeigen ausgeben.The purpose of our invention is to enable without changing the structure or the contacts, encode the sensors and the electronics identify different types of sensors. So can it means, for example, that with chemical sensors, the z for a particular gas. B. carbon monoxide after are assigned, the auxiliary contacts resistance values show between 10 and 100 ohms, the contr certain sensitivity ranges That means if the sensors are in the socket are plugged in and the electronics z. B. 50 ohms Resistance between the auxiliary contacts reads that according to the previous coding of the sensor, a coal monoxide sensor, a measuring range of z. B. 0-500 ppm having. This identification enables the Electronics corresponding, previously coordinated Information values, the manufacturing factors and so correctly identify the sensor and output the corresponding measured values in displays.
