<p>An installation for controlling the level and/or temperature of liquids such as, for example, engine oil, brake fluid, cooling water, fuel, etc. in vehicles, especially in motor vehicles, with the use of temperature-dependent resistances which are incorporated in sensors whereby one or several sensors are so arranged in the liquid to be controlled and are so connected with each other that with the use of electronic threshold switching devices an unequivocal signal is produced when dropping below a predetermined liquid level and/or when exceeding or dropping below a predetermined temperature.</p> |
