ABSTRACT:
A method and a device for transmitting and for measuring resistance values, is particularly provided for use in motor vehicles, for the constant control of airbag systems. In the method and device an exciter signal coupled into a secondary-side resonant LCR circuit from the primary side via inductively coupled coils is interrupted, transmitted back to the primary side of the transformer and is there used for determining the resistance value by evaluating the time constant of the exciter response.
