Abstract (en)
[origin: EP0654773A1] A signal acquisition device is proposed which contains a sensor arrangement (24) having at least one sensor (10) and an evaluation circuit (25) which is spatially separate from the sensor arrangement (24). There is located between the sensor arrangement (24) and the evaluation circuit (25) a connecting line (22) via which the power which is required by the sensor arrangement (24) is supplied and the signal transmission to the evaluation circuit (25) takes place. The sensor arrangement (24) contains a signal-converting device (17) which converts an analog signal (11) output by the sensor (10) into a corresponding digital signal (18) having a predetermined pulse duty ratio (mark-to-space factor) and/or a predetermined frequency which serves to control a current sink (19). The current sink (19) modulates the current flowing in the connecting line (22) by establishing two discrete different values. <IMAGE>
