Abstract
A system for detecting dry running of a pump includes an inlet device to an intake device of the pump for taking in an electrically conductive liquid, and an electrical resistance structure (20) arranged in the inlet device. The electrical resistance structure has a variable resistance value, dependent on wetting with the electrically conductive liquid.
