Abstract

Several techniques used to improve the characteristics of self-excitation vibrating-wire sensor are summarized. First, the new mathematical model and its applications are given. Then, the match of wire and diaphragm for the horizontal wire type sensor to reduce the hysteresis of the sensor is presented. After that, the weak excitation of the wire is stated, which can effectively solve the problem of frequency variations. At last, the techniques of piston-conveying pressure and force conversion can be used to enhance the accuracy and long-term stability of wide range pressures sensors and force sensors.
