Indestructible, High Resolution, Versatile
More beans for the coffee machine? Is there enough water in the steam cooker for the next meal? Is the construction machine likely to tip over? A unique capacitive measuring system helps in all these examples es: capaTEC® from EBE GmbH. High-resolution capacitive sensors based on capaTEC® measure filling level, force, torque and much more.
The capaTEC®-technology was completely developed by EBE and excels by offering high precision and robustness. Even if cost-effective standard modules are used the innovative measuring process allows for highest resolutions in the single-digit femtoFarad range.
The dynamic parametrisation finds the optimum operating point at any time. It achieves the best possible resolution across a wide range of values. Furthermore, the electronics provide stable results across a wide range of temperature and humidity.
The control and evaluation of several electrodes ensures a multi-channel measuring process. This diversity allows for a variable field configuration and the dynamic focussing of the measuring capacity on the desired area.
In addition, capaTEC® measuring systems allow for a spectroscopic evaluation of the field. In this way you can detect presences. Thus, fluid sensors can compensate moisture films.
Apart from the intelligent control and signal evaluation the design of the measuring electrodes is of prime importance for capacitive sensors. EBE has profound experience with the design and optimisation of suitable structures. By means of the 3D-field simulator CST Studio Suite EBE determines the best geometry for the individual application under consideration of the given tolerances.
In many cases the electrodes can directly be integrated on the PCB. This allows for a compact and cost-effective sensor setup. The sensors function contactless, touchless and maintenance-free.
The suitable design of the electrodes and controls make the sensor system robust against parasitic capacitances. Such influences are generated by conductive bodies near the sensor. Interference which might occur by metallic bodies or touch can be avoided in this way.
