ABSTRACT:
A method for operating a photoelectric sensor arrangement having a pulsed light emitting first module, a light receiving and converting second module and a level judging and/or processing third module.The method includes:sending periodically light pulses from the first module towards the second module,producing an analog potential signal at the second module and transmitting the signal to the third module,processing the analog signal at the third module and providing an evaluation or control information or signal depending on the processing results,before transmission to the third module, inverting the analog signal produced by the second module and shifting or offsetting the inverted signal, andat the third module, measuring the inverted and shifted analogue signal at least once between two successive light pulses and processing the measured value(s).
