| Aim: Modern technical equipment often includes, as vital components, transducers for measuring different physical and chemical quantities. These transducers are integrated parts of the equipment, and deliver electrical outputs, which can be read directly or fed into a data acquisition system in order to perform signal processing and analysis. The course deals with measurements of electrical and non-electrical quantitites and gives the student necessary knowledge to understand and be able to communicate with specialists in these areas. |
|||
| Prerequisites: (valid for students admitted to programmes within which the course is offered) Former courses in basic technology Note: Admission requirements for non-programme students usually also include admission requirements for the programme and threshhold requirements for progression within the programme, or corresponding. |
|||
| Supplementary courses: KI: TFKI50 Computerized measurement systems |
|||
| Organisation: Lectures, lessons and laboratory experiments within measurement and trasducer techniques. The laboratory experiments are adapted to the alignment within MI and KI respectively. |
|||
| Course contents: Measurement and transducer technique. Basic measurements of current and voltage in electronic circuits with electrical components as diodes, transistors and operational amplifiers. Important circuits for measurement applications are analyzed. Current and voltage sources are studied from measurement applications points of view. General and special instruments and methods are handled. Modern oscilloscopes, instrument and methods for measurements of important process parameters like flow, temperature, pressure and level. Fundamentals of e.g. flow measurements on air and water in a station utilizing Pitot-static-tube, obstruction-transducer, turbine instrument and inductive flow meters with connections to flow technique. Temperature measurements using thermoelements resistance thermometers and pyrometers are studied. Parameters in conjunction with mechanical processes as revolution number, velocity and acceleration are studied. Qualities and constrains of different types of transducers are focused. Influence from electric and magnetic interfering sources together with reduction methods utilizing shielding and earthing are handled. Signal processing and the conception "the measurement chain". Error analyses and presentation of measurement data. Calibration with ISO9000. |
