A quartz force sensor with differential output has been developed.It consists of a spoke elastic structure and two quartz resonant force sensing devices.One is arranged at positive region
another is arranged at negative region.They sense force and make up of differential output signal to realize zero thermal and time shift self compensation.The structure character of elastic beam is analyzed.The double terminal force device performance
and the process of manufacture is introduced.The result shows that the sensor’s measurement range is 0
