Abstract：Introduced the principle and technical performance of vibration sensor with double outputs, that based on big damping ratio. By using the electric capacity sensing and the big damping ratio moving coil sensing technology, acceleration and velocity could be measured simultaneously with an vibration sensor. The bandwidth and range of the vibration sensor are expanded by using big damping ratio moving coil technology. The paper give the system equation, get the frequency characteristic and sensitivity of acceleration and velocity. As a new instrument for engineering vibration measurement, the sensor could be used in low and ultra low frequency vibration measurement for Civil and Hydraulic Engineering and strong gound motion.
