SU976312A1 - Device for measuring load and application angle thereof - Google Patents

Description

The invention relates to a measuring technique and can be applied to measure the load and its angle to the horizon when testing structures and structures.

A device is known for determining the horizontal and vertical component of the load acting on a cable containing a two-component strain gauge load cell P)

However, this device does not allow to measure the load and the angle of its application with an arbitrary position of the device in space.

The closest to the invention to the technical essence is a device for measuring the load and the angle of its application, which contains an angle sensor, a dynamometer and an horizontal sensor G2. .

A disadvantage of the known device is the impossibility of measuring the load and its angle

at arbitrary device position

in space.

The purpose of the invention is to provide

remote measurement capabilities with arbitrary location

roystva in space.

This goal is achieved by introducing a second horizontal sensor and two electrical mechanical systems, the first horizontal sensor together with the first electromechanical system form a crepe stabilization circuit, and the second horizontal sensor together with the second electromechanical system form a contour stabilization of the device in pitch, you-. its travel is related to the angle sensor,
