卧式平衡机测试仪用来对风叶进行不平衡量的检测，但它只能给出不平衡值而无记录功能，因而不能实现数据的复查。为此我们在该测试仪的相应处获得测量信号，经本文介绍的数来仪对信号进行采集与处理，从而可对测试量实现实时采集、存储和显示，并可以与IBMPC机相联，大大提高了原测试仪的功能。本采集器也可用于一些相似设备、仪器的改造，它比新设计一个测试系统既省时间又省费用。
Horizontal balancer tester is used to detect the unbalance of blades, but it can only give the unbalance value without recording function, so it can not realize the data review. To this end, we obtain the measurement signal at the corresponding place of the tester. The number of the instrument introduced in this paper collects and processes the signal so that the test quantity can be collected, stored and displayed in real time, and can be connected with the IBMPC machine. Improve the original tester function. The collector can also be used for some similar equipment, instrument transformation, it is more than a new test system design saves time and money.
