【Abstract】 In order to measure the continuously dynamic obliquity,we need to put forward a inclinometer which has a good dynamic performance,and in order to decrease the error,we adopt the digital signal for the measuring.This instrument is based on gravity principle and belongs to pendulum-model inclinometer.The angle of pendulum-waver is measured which has been thansformed into digital signal by the encoder.The digital signal is transacted by the DSP.In the frame of measurement we adopt the magnetoelectric-damp elements and the pendulum can stabilize at the balance place rapidly.This instrument has a good transient performance.It is proved by practice that the inclinometer can measure any obliquity between-45°to +45°and its precision may up to ±0.07%,and the readings can be stable within 0.05 second.The measurement capacity of the inclinometer is very strong and the precision is high and it has a good linear characteristic and its capacity of anti-jamming is very well and its structure is simple and we can get the reading swiftly.This inclinometer can adapt well to the demand of continuous measurement.更多还原
