Initial situation
The magnetic field generated by electric currents allows a simple realization of very accurate non-contact current sensors. In most cases, however, the magnetic field is guided through a magnetizable core or flux concentrator, or the sensor itself consists of magnetizable materials. However, this leads to the fact that saturation, hysteresis and other non-linear effects can negatively influence the characteristics of the measurement.
With the integrated 3D Hall sensors from Fraunhofer IIS, on the other hand, it is possible to build current sensors entirely without magnetizable materials. Two different processes have been developed on this basis, which are also already being successfully produced and marketed by our customers.
Our technology
In the following, two different approaches of current measurement will be explained to you. Both approaches are contactless and work via the magnetic field.
An integrated Hall sensor array allows multiple currents to be measured in a confined space. This approach is well suited for installation technology.
The measurement direction parallel to the chip surface can be optimally utilized in sensor technology that can be retrofitted during operation. Multiple sensors are applied to a flex track, which can then be mounted around a current-carrying conductor without having to interrupt the current for this purpose.
