Abstract

The invention relates to the geodesic instrument making, particularly to the devices for measuring the object altitude irrespective of the slope angle. the device may be used for determination of clearance and intersection of aerial power lines.The purpose of the invention is the enlargemet of the measurement range.The altimeter consists of a body, an optical system with on object glass, a reflecting element, an ocular and a measuring scale. The object glass is situated between the reflecting element and the ocular, the measuring scale is installed in front of the reflecting element; between the object glass and the ocular there is a grid with a graduation line, and the optical axle in Z-form has an angularity smaller than 90°. In the first angularity of the optical axle there is the reflecting element, made of two parts, one of which is turning. In the second angularity is placed the object glass in form of lens, one surface of which is covered by a reflecting layer. The measuring scale may be executed in the form of a weight-rule.Drawings: 3
