Linear Variable Differential Transducers (LVDT) has been manufactured in small dimensions as an absolute position transducer with high accuracy but limited range and linear output for years. In this research, an experimental LVDT with long range has been built in large size. Core is selected from CK45 steel material with heat treatment and a layer...

Context 1
... signal of LVDT, which is differential voltage between secondary coils, is changed due to axis displacement of core (figure 3). Usually this AC output is changed to DC current after an amplification based on figure 4. figure 3, it is shown that if core is near S1 coil rather to S2 coil, more flux is generated on S1 and less on S2. So, E1 inducted voltage will increase and E2 will decrease and finally output voltage of (E1-E2) is obtained. ...

... and left part each is contained 4 layers and 92 turn for each layer so that the number of turns of coils ratio is 1 to 10. Wire ends from primary and secondary are taken out and as supply a 12 volts AC voltage with 50 Hz frequency is supplied to primary coil. One end of secondary coil is connected internally and the other sides are monitored on oscilloscope (based on figure 3 and 4) but they can be monitored after an amplification class too. But for prevention of amplification disturbance this stage is negotiated. ...

Applying additive manufacturing (AM) technologies in fabricating aluminum alloy automotive components can significantly enhance vehicle light-weighting through optimized design. By varying the AM process parameters, the resultant microstructure can be substantially altered, even post-heat treatment. Given that machining operations remain essential...
The article presents the results of a research of elastic properties of a bondless single-component abrasive tool (SCAT) after sintering. The method of determining the modulus of elongation and porosity based on theoretical and experimental data is used. The dependency between the modulus of elongation and porosity, as well as experimental formulas...
