Displacement measurement. Article can not be downloaded. For high precision displacement measurements, SmarAct offers the PICOSCALE Interferometer, a powerful sensor with picometer resolution.Based on an extremely compact Michelson interferometer, non-invasive displacement measurements with low restrictions on the target reflectivity can be realized very … Linear Proximity Sensors When an AC flows through a coil, magnetic flux occurs in the coil. Ser. Article can not be printed. This chapter illustrates the displacement measurement, which defines that the displacement sensors measure the distance between a start position and an end position. 0000004667 00000 n displacement, and profile utilise strain gauges, dial gauges and other mechanical or electrical sensing devices. To measure displacement, apotentiometer is typically wired in avoltage divider configuration. Download PDF Abstract: Quantum mechanics dictates that the precision of physical measurements must be subject to certain constraints. the capacitive sensor was used to measure displacement rather than load. 87 0 obj <>/Filter/FlateDecode/ID[]/Index[71 39]/Info 70 0 R/Length 88/Prev 58907/Root 72 0 R/Size 110/Type/XRef/W[1 2 1]>>stream : Conf.

The displacement moves the central plate between the two outer plates so if initially the distance between plate 1 &2 equal the distance between plate 2 & 3 then C1=C2 And for small displacement x So when C1 is in one arm of an ac bridge and C2 in other arm then the result out balance voltage is proportional to x The circuit diagram of capacitive transducer, which is used to measure displacement is shown in below figure. 22 ± 25 6.
