Abstract

FIELD: measuring equipment, particularly for determination of apparatus and object inclination angle during construction, particularly inclination angles relative to horizontal plane. SUBSTANCE: method involves measuring projection value of gravitational acceleration onto sensitivity axis of transformer which transforms linear acceleration value into output signal; determining transformer position relative horizontal plane or local vertical for inclination angle estimation on the basis of projection values of gravitational acceleration onto two sensitivity axes which are selected when the third axis direction coincides with direction established by allowable inclination angle of any sensitivity angle in relation to vertical plane; measuring value of gravitational acceleration projection into direction of three perpendicular axes of sensitivity to linear accelerations. Digital device for inclination angle measurement comprises body having mounting unit, inertia meter for gravitational acceleration measurement having electronic circuit for linear acceleration value transformation into visual information concerning inclination angles, and self-contained power supply for electronic circuit. Mounting unit is formed as five flat mounting bases and two prismatic mounting bases. Three flat mounting bases are perpendicular to each other and two flat mounting bases are parallel thereto. Prismatic mounting bases are perpendicular to each other and are formed parallel to two corresponding flat mounting bases. Inertia meter for gravitational acceleration measurement is formed as three-axis meter and fixedly secured relative mounting bases. Electronic circuit for meter signal transformation has microprocessor with model of mounting base positioning error and inertia meter positioning error. EFFECT: increased measurement accuracy, possibility of automation, enhanced responsiveness, extended range of applications. 7 cl, 2 dwg
