[Translate to EN:] Product Image of the Low Pressure Sensor by Marquardt. The background shows the inside of a laundry drum in which the water is standing. The sensor is used to regulate the water level.

    Make home appliances more efficient

    More accurate than before: We present our new generation of Low Pressure Sensors for water level detection.

    Sustainability through precision

    With its mechatronic competence, Marquardt is a specialist for sensors which have everything under control: Temperature, turbidity, water consumption, detergent concentration and flow rate are measured in washing machines and dishwashers. The result is not only radiant cleanliness of laundry and dishes, but also a significant reduction in resource consumption. This way the consumer saves money and the environment is protected.

    New energy guidelines present major challenges for manufacturers of household installations for heating and air-conditioning. Here, too, Marquardt is leading the way: We develop sensors which measure the flow and pressure of air, gas and water in heating, air-conditioning and sanitary systems as well as in heat pumps and solar thermal systems. The components are approved, among other things, for use in drinking water treatment plants. Marquardt offers various technologies from turbine driven to non-contact flow measurement, all of which have one thing in common: you get quality.
