Abstract :
In this paper, we research the mechanical sensitivity of the vibration sensor; The mechanical sensitivity mathematical model is developed in function of the relative movement modulus in firstly and in function of the measurement error in secondly. The developed model allowed improving the mechanical sensitivity by enhancing the performance of vibration sensor (the best choice of damping rate and the frequency ratio). The right choice of the damping rate and the frequency range allowed keep the mechanical sensitivity constant. This model is validated by computer simulation and experimental tests.
