Intelligent Inductive Measurement of Position and Path
Individually developed position sensors and path measuring sensors from EBE sensors + motion measure the desired values in a wide range of applications. The intelligent and inductive sensors are particularly suitable for areas with extreme ambient conditions.
EBE position sensors provide a robust and cost-effective means of path measurement. Especially in rough environments, it is essential to determine path or angle reliably. These include commercial vehicles, industrial plants or sorting machines. The development of position sensors is made according to application-specific requirements by the customers.
The function of position sensors is based on the induTEC® technology developed by EBE. It forms the basis of our product development. The inductive measurement principle: Position and displacement of a metallic or permeable target are recorded by a coil structure. Differential coil structures compensate temperature and aging influences as well as the scattering of components. Position sensors can be designed cost-efficiently by realizing the coils as PCB inductivities. The arrangement can be integrated in a space-saving way. Sensitivity and tolerances are sufficient for many applications. Costs for the winding and contacting of external coils are avoided. In more complex and particularly demanding applications, wound sensor coils can be used. They allow to generate a magnetic measuring field which offers additional degrees of freedom. EBE manufactures the coils according to professional standards on winding and grouting machines. This email address is being protected from spambots. You need JavaScript enabled to view it..
Application Example: Identification of Packagings
Similar to the recognition of a bar code by red or infrared light, metallic structures can be recognized inductively. The EBE system for the identification of packagings offers an intelligent application based on the induTEC® technology.
A coil system recognizes the metallic structures embedded in a packaging and reads them out. Packaging and reading unit need not be in contact. An optical connection is not required either. The metallic structures can be printed onto the packaging. Likewise, it is possible to hide them under varnishing resp. coating. In this way, the originally planned design of the packaging is preserved, including pictures, graphics, advertisement and product information.
A special variant is the arrangement of the coding structure in concentric form. It is ideally suited for round shapes which can be reliably identified independent of the orientation/application of the packaging to the reading device. Depending on the total number of conditions to be coded, it is also possible to use a kind of QR code structure resp. matrix in the required size resp. quantity.
