Method for multi-channel measurements of tested value and the multi-channel device for execution of this method

摘要

in the each sensor sends and receives its own signal continuously, the work of non mutually harmonicznymi working frequencies frequencies, and during measurement switches cyclically exit channels advantageously using multiple measurement xerox spd.in the each channel is integrated with the own digital / size measurement test and processing system and exit channels are connected with the measuring multiplekserem which is connected through the communication module to the computer. method and device are suitable in particular for testing tubes heat exchangers.
