Abstract (en)
[origin: WO2020074289A1] The invention relates to a system (1) for detecting dry running of a pump (4), which system comprises a feed device (10) to an intake device (60) of the pump (4) for taking an electrically conductive liquid (2) in, and an electrical resistance structure (20), which is arranged in the feed device (10). The electrical resistance structure (20) has a resistance value that varies depending on whether it is wetted with the electrically conductive liquid (2).
