Some new developments of self-excitation vibrating-wiresensor technology and their applications into force sensor for pulling force measurement of anchor rope are described in this paper. (1)week excitation has been used to slove the problem of frequency variations. (2)principle of minor deformation slove the problem of long-term stablitity. (3)The new mathematical mode for the vibrating-wire sensors and GSJ-2type multi-function instrument increase the accuracy of vibrating-wire sensors.
