The design of a RFID-enabled temperature sensor is described in this paper. In this sensor, a change in temperature causes structural beams to bend, which results in a proportional displacement of the plates of the capacitor. Plates\' displacement results, in turn, in changing the value of its capacitance. The capacitor of the sensor is coupled to the LC resonant network of a passive RFID tag. ...

In welded tube manufacturing, the electric resistance welding (EW) process begins with a coiled plate of steel with appropriate thickness and width to conform the produced tube. The strip is pulled through a series of rollers that gradually cold conform it into a tubular shape. The edges of the cylindrical plate come together forming a V. The strip edges are heated with a high frequency power ...

Prototype Fast Breeder Reactor (PFBR) is a 500MWe, sodium cooled, pool type, mixed oxide (MOX) fuelled reactor. Sodium flow measurement in various loops of the reactor is of prime importance from the operational and safety aspects. To measure the flow of electrically conducting sodium in large secondary circuit pipes, probe type permanent magnet flowmeters (PTFM) are used. PTFM works on the ...

Fault Current Limiters (FCLs) are expected to play an important role in the protection of future power systems due to the rising levels of the short-circuit currents. The inductive FCLs, comprising magnetic cores and one or more dc and ac windings, are particularly interesting because they inherently react on the fault. The so-called open-core FCL configuration employs only one magnetic core for ...

Power grid voltages and currents may be distorted due to presence of harmonics. Measurements of such voltage with harmonics may be performed using newly developed instrument with a small air-core transformer based probe as the input unit. The probe must be shielded against unknown external electromagnetic fields. At the same time, the probe must remain linear throughout the range of frequencies. ...

Dielectrophoresis is a phenomenon in which a force is exerted on a dielectric particle when it is subjected to a non-uniform electric field. In this research, we analyze dielectrophoretic (DEP) force using a geometry containing two electrodes, one with SiO2 and one without, with a gap between them. The relevant governing equations include the DEP force, the electrohydrodynamic and corresponding ...

The use of a reaction sphere as an actuator used by satellite Attitude Control System was proposed over twenty years ago. In principle this concept assumes the use of a single reaction sphere which can be accelerated in any direction instead of a set of reaction wheels. The solution discussed in this work has been proposed and patented by CSEM company. Contrary to conventional ball bearing ...

Gaseous exhaust of different industries contains dust particles of different chemical precipitates that are harmful for the environment. Electrostatic Precipitators are very often used in industries like power plant to filter their gaseous exhaust and to prevent the atmosphere to being polluted. Electrostatic Precipitators are very efficient in dust particle collection from the flue gas. ...

Research at Fraunhofer EMI addresses the response of materials in extreme dynamic loads. Besides mechanical or thermal loads, intense electric pulse currents also represent an extreme dynamic load. Experimentally, metallic samples, mainly thick wires, were electro-mechanically loaded with currents up to 400 kA. For this purpose, a test rig containing a high-voltage pulsed power supply and ...
