  1. 1. Improving Product Level Sensing in Filling Tubes

    Master-uppsats, Lunds universitet/Innovation

    Författare :Hannah Schrewelius; [2023]
    Nyckelord :level sensing; hygienic design; manufacturing; product development; Technology and Engineering;

    Sammanfattning : This thesis examines the possibility to improve the product level sensing in one of Tetra Pak’s filling machines, because the current solution does not detect this with the desirable precision, as well as measuring range. Today, a magnetic float is used together with 16 separate capacitive sensors. LÄS MER

  3. 2. The Irrigator : Autonomous watering robot for homes

    Kandidat-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Henrik Lind; Jacob Janssen; [2019]
    Nyckelord :Mechatronics; Automated Homes; Automatic Irrigation System; Microcontroller; Line Follower; Capacitive; Resistive; Moisture Sensors.; Mekatronik; Automatiserade hem; Automatiserat bevattningssystem; Mikrokontroller; Linjeföljare; Resistiv; Kapacitiv; Fuktighetssensor.;

    Sammanfattning : Inspired by the trend of automated homes, this thesis examines the possibility of designing a cheap and autonomous robot that will water plants effectively at home. Many existing solutions are cumbersome and not sufficiently effective, often due to flexibility and risk of over watering. Therefore this thesis examines a wheel based approach. LÄS MER

  4. 3. Vätskenivåmätning för nivåreglering till doppvärmare : I sura och basiska lösningar

    Kandidat-uppsats, Mittuniversitetet/Avdelningen för elektronikkonstruktion

    Författare :Morteza Mohammadi; [2018]
    Nyckelord :Capacitive level sensors; liquid level; copper laminate; PVDF; Teflon; Kapacitiva nivågivare; vätskenivå; kopparlaminat; PVDF; Teflon;

    Sammanfattning : Idag är de flesta kemiska industrier försedda med system för nivåreglering. Dessa system syftar till att kontrollera vätskenivån i en behållare, trots störningar i form av smuts och skum. För denna process finns olika modeller av nivågivare på marknaden, men de flesta är antingen dyra eller kräver mycket rengöring och underhåll. LÄS MER

  5. 4. Investigation of integrated waterlevel sensor solution forsubmersible pumps : A study of how sensors can be combined towithstand build-up materials and improvereliability in harsh environment

    Master-uppsats, KTH/Maskinkonstruktion (Inst.)

    Författare :Sarah Abelin; [2017]
    Nyckelord :sensor fusion; support vector machine; level sensors; drainage pumps; water; sensor fusion; support vector machine; nivågivare; dräneringspumpar;

    Sammanfattning : Monitoring water level in harsh environment in order to handle the start and stop function of drainage pumps has been a major issue. Several environmental factors are present, which affect and disturb sensor measurements. LÄS MER

  7. 5. A Technical Evaluation of Capacitive Level Sensors for use in Hemodialysis Machines on Chambers Filled with Dielectric Liquids

    Master-uppsats, Lunds universitet/Avdelningen för Biomedicinsk teknik

    Författare :Viktor Stevander; Viktor Petersson; [2016]
    Nyckelord :comb-finger; parallel fingers; capacitive sensor; Electrical engineering; Electric measurement; hemodialysis; dialysis machine; Technology and Engineering;

    Sammanfattning : A series of tests were performed to explore the limits of two capacitive level sensors using the principle of parallel finger layout (sometimes called comb fingers) for sensing. The goal was to present a decision basis for Baxter to use when choosing a sensor to implement in their next generation hemodialysis machine. LÄS MER
