Abstract

W sposobie każdy czujnik wysyła i odbiera własny sygnał w sposób ciągły, czujniki pracują z częstotliwościami roboczymi niebędącymi wzajemnie częstotliwościami harmonicznymi, a podczas pomiaru przełącza się cyklicznie wyjścia kanałów pomiarowych, korzystnie przy użyciu multipleksera programowego. W urządzeniu każdy kanał pomiarowy jest zintegrowany z własnym przetwornikiem wielkości badanej i układem przetwarzającym, a wyjścia kanałów pomiarowych są połączone z multiplekserem, który połączony jest poprzez moduł komunikacji z komputerem. Sposób i urządzenie nadają się w szczególności do badania rurek wymienników ciepła.In the method, each sensor sends and receives its own signal in a continuous manner, the sensors work with operating frequencies that are not mutually harmonic frequencies, and during measurement the outputs of the measuring channels are cyclically switched, preferably using a software multiplexer. In the device, each measuring channel is integrated with its own transducer of the test quantity and processing system, and the outputs of the measuring channels are connected to a multiplexer, which is connected through a communication module with a computer. The method and apparatus are particularly suitable for testing heat exchanger tubes.
