摘要
In wind tunnel measurement of surface drag a force meter with high sensitivity and accuracy is urgently needed.This paper reports the development of the automatically balancing force meter which is a new device not yet seen before.The design principle,software and hardware,and the application of this meter are presented in this paper.Its accuracy is 0 5%,repetition 0 1%,responce time 5ms,sampling period 100μs.
