FIELD: physics, measuring. ^ SUBSTANCE: invention concerns devices for measuring of a diversion of object in a vertical plane and can be used for the control and bearing of a standing of railroad tracks. Pendulum data unit of level contains massive pendulum, bath with damping fluid, suspension axle, two ball-bearing seats, and the corner data unit. Two accelerometres and the calculator are entered into this plan. Thus accelerometres are located on a pendulum so, that the axis of sensitivity of one is guided horizontally and perpendicularly to the suspension axle pendulum, and the axis of sensitivity of other accelerometre is guided vertically, exits of the first and second accelerometre are joined to the first and second inlet of the calculator accordingly, the output of the data unit of a corner is joined to the third inlet of the calculator. The accelerometres mounted on the pendulum, measure vertical and horizontal vibrations making acceleration. On these components in the calculator the resultant of vibrating travel of the pendulum support and an angle which it makes with a horizon line is spotted. On these parametres value of an angle of deflection of a pendulum from horizon under the influence of skew vibration which is subtracted from indications of the data unit of a corner is calculated. ^ EFFECT: expansion of functionality of application of the data unit of level at great values of the linear vibration at the expense of neutralisation of vibrating detrusion of zero of a pendulum in instrument readings. ^ 2 dwg |
