Abstract
Przetwornik pomiarowy do badania materiałów przewodzących metodą prądów wirowych jest wyposażony we wspornik, do którego przymocowany jest liniowy aktuator (2) oraz ma magnesy trwałe (2) wprawiane przez liniowy aktuator (2) w ruch posuwisto-zwrotny. Element pomiarowy połączony jest ze wzmacniaczem (6), który połączony jest z przetwornikiem analogowo-cyfrowym (7), który połączony jest z układem sterującym (8), połączonym z kontrolerem (9), który połączony jest z liniowym aktuatorem (2). Istota zgłoszenia polega na tym, że dwa magnesy trwałe (3) połączone są z aktuatorem liniowym (2) za pomocą drugiego wspornika (4), a do wolnego końca każdego z magnesów trwałych (3) przymocowany jest element pomiarowy w postaci dwóch cewek pomiarowych (5) - po jednej na każdy magnes trwały (3). Obie cewki pomiarowe (5) połączone są różnicowo.The measuring transducer for testing conductive materials using the eddy current method is equipped with a bracket to which a linear actuator (2) is attached and has permanent magnets (2) set in reciprocating motion by the linear actuator (2). The measuring element is connected to an amplifier (6), which is connected to an analog-to-digital converter (7), which is connected to a control system (8), which is connected to a controller (9), which is connected to a linear actuator (2). The essence of the application is that two permanent magnets (3) are connected to the linear actuator (2) using a second bracket (4), and a measuring element in the form of two measuring coils ( 5) - one for each permanent magnet (3). Both measuring coils (5) are connected differentially.
