Abstract

Abstract

A parallel multi channel high speed data acquisition system has been designed for dynamic flow measuremaent in turbomachine.With the swallowing and spitting capacity of 800 kc/s in all,the system can parallelly sample and process 16 channel signals.The structure,principles of operation,function and operation of the system are described in detail and two typical application examples are given.
