INCLINOMETER Russian patent published in 1998 - IPC

FIELD: instrumentation engineering. SUBSTANCE: inclinometer has probe which accommodates upper pendulum, lower pendulum, stator, rotor, and computer unit. Three-component magnetometer is positioned on probe. Lower pendulum is coupled to its body by means of spring. Angle-data transmitter is arranged on axle of lower pendulum which includes damper. Upper pendulum is suspended freely in its supports, and it has unlimited angle of turn. Upper pendulum carries rotor. Stator of sine-cosine rotary transformer is positioned on upper pendulum body. Axes of pendulum suspensions are aligned with longitudinal axis of probe. Measuring axis of lower pendulum perpendicular to its arm and suspension axis is aligned with one of lateral axes of probe. Outputs of three-component magnetometer, sine-cosine rotary transformer and angle-data transmitter are connected to respective inputs of computer unit. EFFECT: higher measurement results. 3 dwg
