Abstract

Kod mernog uredjaja (10) za odredjivanje puta pomeranja ili ugla obrtanja predmeta merenja odnosno mašinskog dela, kalem (19) je postavljen na čauri (16), a kalem (20) na cilindričnom jezgru (17). Čaura (16) i jezgro (17) postavljeni su na držaču (15). Jezgro (17) zahvata u čauru (13) od nefromagnetnog, ali električki provodnog materijala. Nadalje, čaura (16) se vodi preko jezgra (12) od feromagnetnog materijala. Pri tome su čaura (16) i jezgro (12) kao i jezgro (17) i čaura (13) koaksijalno izvedeni. Na osnovu efekta vrtložnih struja, induktivnost u kalemu (20) se smanjuje, dok se na osnovu feromagnetnog efekta induktivnost u kalemu (19) povećava. Povezivanjem kalemova (19, 20) u rezonatno oscilatorno kolo (42) greške pri merenju se delimično eliminišu, a merni signal pojačava.With the measuring device (10) for determining the path of movement or the angle of rotation of the measuring object or the machine part, the coil (19) is placed on the sleeve (16), and the coil (20) on the cylindrical core (17). The sleeve (16) and the core (17) are mounted on the holder (15). The core (17) engages in a sleeve (13) of non-magnetic, but electrically conductive material. Furthermore, the sleeve (16) is guided through a core (12) of ferromagnetic material. The sleeve (16) and the core (12) as well as the core (17) and the sleeve (13) are coaxially made. Based on the effect of eddy currents, the inductance in the coil (20) decreases, while based on the ferromagnetic effect, the inductance in the coil (19) increases. By connecting the coils (19, 20) to the resonant oscillator circuit (42), the measurement errors are partially eliminated, and the measurement signal is amplified.
