  1. 6. Overheat protection for immersion heaters : Analysis of analog and digital temperature sensors

    University essay from Mittuniversitetet/Avdelningen för elektronikkonstruktion

    Author : Tina Helmisaari; [2018]
    Keywords : immersion heater; temperature sensor; overheat protection; thermistor; DS18B20 ; PT-100; Adafruit Feather Adalogger M0;

    Abstract : Immersion heaters are used by industries to heat fluids. The element of an immersion heater need to be fully immersed into the heated liquid, otherwise it could be subject to overheat. READ MORE

  3. 7. Implementation of PID control using Arduino microcontrollers for glucose measurements and micro incubator applications

    University essay from Uppsala universitet/Fasta tillståndets elektronik

    Author : Hugo Andersson; Viktor Mattsson; Aleksandar Senek; [2015]
    Keywords : ;

    Abstract : The task is to build a low-cost thermostat and design necessary elements to perform a study on water mixed glucose-impedance at different temperatures and cell growth in a temperature-controlled incubator housing a magnetic field of up to 3 mT. The incubator was designed in solidworks and made to fit petri dishes of two relevant sizes and necessary wiring. READ MORE

  4. 8. On-line estimation of junction temperatures in power modules

    University essay from Lunds universitet/Industriell elektroteknik och automation

    Author : Josefin Lund; [2014]
    Keywords : junction temperature estimation; foster circuit; thermal Ohms law; thermal resistance; thermal capacitance; time constant; Technology and Engineering;

    Abstract : It is critical for the durability of power modules to maintain low enough temperature in their components (IGBTs and diodes). The goal of this project was to examine methods to estimate the junction temperature of components in an IGBT module in real-time. READ MORE

  5. 9. Evaluation of on-line cell viability and L-lactate measurements in soft sensor for mammalian cell cultures

    University essay from Linköpings universitet/Teknisk biologi; Linköpings universitet/Tekniska högskolan

    Author : Alexander Reissig; [2014]
    Keywords : hybridoma; B lymphocytes; batch reactor; soft sensor; lactate; L-lactate; radio-frequency impedance; BioSenz; enzyme thermistor; overflow metabolism;

    Abstract : Increasing demand on more effective cell culture reactors has driven optimization works to increase output of products. This has led to development of soft sensors that uses mathematical formulas to increase the available information for the parameters during runs. READ MORE

  6. 10. Development of a Temperature Controlled Cell for Surface Enhanced Raman Spectroscopy for in situ Detection of Gases

    University essay from Umeå universitet/Institutionen för fysik

    Author : André Appelblad; [2014]
    Keywords : temperature control; Raman scattering; surface enhanced Raman spectroscopy SERS; SERS substrate; volatile substances; Peltier module; thermistor; PWM; H-bridge; PI D control.; temperaturkontroll; ytförstärkt ramanspektroskopi; SERS; flyktiga ämnen; Peltierelement; thermistor; PWM; H-brygga; PI D -regulator.;

    Abstract : This work describes a master’s thesis in engineering physics at Umeå University carried out during the spring semester of 2014. In the thesis the student has constructed and tested a temperature controlled cell for cooling/heating of surface-enhanced-Raman-spectroscopy (SERS) substrates for rapid detection of volatile substances.
