The new mathematical model for the vibrating wire sensors and its application are described. The matching of wire and diaphragm of horizontal wire type sensors is presented. Weak excitation has been used to solve the problem of frequency variations and thus increase the measuring resolution. At last, in order to increase the accuracy as well as long term stability of wide range pressure sensors and force sensors, the techniques of piston conveying pressure and force conversion are developed.
