The Research of Uniaxial Inclinometer Being Sensed by Capacitance

The material of sense organ is beryllium-bronze, it has good elasticity, and fitting to make elastic vibration element, a kind of inclinometer being sensed by capacitance is researched, the signal pick-up circuit of dynamics sensor being sensed by differential capacitance is developed. Electron components of the circuit are listed, after analysing the circuit performance, a direct ratio relationship between output voltage and tilted angle is gained. The experiment shows that the sensitivity of inclinometer is about 12.67 mV/°.
