SCHALTUNGSANORDNUNG FÜR EIN SENSORELEMENT |
摘要 |
<p>A circuit arrangement (11) has an activating circuit (13) for a sensor element (12) of a touch contact switch, which in one embodiment of the invention contains a frequency generator (16). The frequency generator (16) generates a frequency-modulated activating signal (17), which is applied to the sensor element (12). In another embodiment the forming of the activating signal (17) takes place in a microcontroller (48), containing eventually the activating part (13) and or the evaluation of the signal. Through passing through a large frequency range for the activating signal (17), the influence of extraneous signals, even when using a lower signal voltage, is minimized.</p> |
