Zařízení pro bezkontaktní kontrolu povrchu, zejménamateriálu ve tvaru provazce, například bimetalického drá-tu z hliníku a mědi, vyznačující se tím, že zkušební sonda(4), do které jsou vestavěny cívka (3) zkušební sondy (4)adolaáovací kondenzátor (13) a je připojena spojovacím ka-belem (14) jímž jsou za sebou zapojeny omezovač (7), kmi-točtový detektor (8) a článek (9) posuvu fáze o 90°, a vý-stup automatického dolaáování kmitočtového detektoru (8)přes paralelně zapojený RC-článek (10) s velkou časovoukonstantou je spojený s oscilátorem (6), paralelně zapo-,jeným integrovaným obvodem (11) a za ním zapojeným ana-lyzátorem (12), přičemž indukčnost cívky (3) zkušební son-dy (4) tvoří s kapacitou spojovacího kabelu (5) a kapaci-tou kapacitního děliče (22), včetně kapacity dolaáovacíhokondenzátoru (13) rezonanční okruh.An apparatus for contactless inspection of a surface, in particular a rope-shaped material, for example a bimetallic aluminum and copper wire, characterized in that the test probe (4), in which the test probe coil (3) is embedded, (4) and a capacitor ( 13) and is connected by a connecting cable (14) through which the limiter (7), the digital clock detector (8) and the phase shift element (9) by 90 ° are connected, and the frequency detector output (8) ) via a parallel-connected large-time RC-cell (10) is connected to an oscillator (6), a parallel-circuit integrated circuit (11) and an analyzer (12) connected thereto, wherein the coil inductance (3) is a test son - (4) forms a resonant circuit with the capacity of the connecting cable (5) and the capacitance divider (22), including the capacitor capacitor (13). 2. Zařízení podle bodu 1, vyznačující se tím, že vezkušební sondě (4) na držácích (18) z izolačního materiálu,například polyamidu, jsou vyměnitelně rozmístěny dvě vo-dicí smýkadla (2), přičemž jejich průchozí otvory jsourozmístěny podél protilehlých os, a jejich vstupní otvoryjsou otočeny navzájem ve směru, protilehlém směru průchodumateriálu (1) ve tvaru provazce.2. Apparatus according to claim 1, characterized in that two guide slides (2) are replaceably disposed on the holders (18) of insulating material, for example polyamide, with their through holes disposed along opposite axes. and their inlet openings are rotated relative to each other in the direction opposite to the rope-shaped material passageway (1). 3. Zařízení podle bodu 1, vyznačující se tím, že cívka(3) zkušební sondy (4) je upevněna v dutých válcovýchrozpěrkách z izolačního materiálu, například textolitu. 1 výkres3. Device according to claim 1, characterized in that the coil (3) of the test probe (4) is fixed in hollow cylindrical struts of insulating material, for example textolite. 1 drawing
