出はおこなわれない。The high-precision tension #4 wire ruler known from East German Patent Specification 139 295 is provided with a kitria, in which a steel wire system consisting of a number of parallel thin steel wires is stretched between the holding device and the tensioning device. , a scanning system is provided for scanning the FA line system in its longitudinal direction. This evaluation device uses, for example, a scanning system that scans a steel wire system inductively or capacitively.
From the measurement values sent from the system, taking into account the slack of the steel wire,
Characteristic values of flatness and straightness of the sample body are investigated. In the case of this tensioned steel wire ruler, only the slack of the steel wire is corrected, and the steel wire is homogenized by demagnetization as well as attenuation of the alternating magnetic field. However, there is no detection of local variations in the permeability/uR of the steel wire system which may still remain in the steel wire system and distort the measurements.

．． In the case of the arrangement shown in '4, the measuring deflection is maintained, as it were, at zero, i.e. the bridge circuit is operated only with the diagonal 1 axis "zero" balanced. A differential arrangement of two non-contact inductive displacement transducers relative to the tensioned steel wire system must be adjusted. In that case, the tensioned steel wire system is located at the geometric center between the two displacement transducers (scanning systems), which are generally not identical, J or the residual Δ1. - It will be located at a geometric center that is highly dependent on the old effect.

べて５１０％変えられているのが有利である。The technical problem on which the invention is based is to compensate for the influence of local differences in the magnetic and electrical material properties on the measurements by simple means in tensioned steel wire rulers. A tensioned steel wire system is stretched using a mounting device onto a frame, the frame having guides and supports in its longitudinal direction, receiving at least two scanning systems and movable perpendicularly to the guides. (a tension system in which a carrier is mounted so as to be movable along a guide, and in which a sensor for scanning the surface of the object to be measured and an evaluation device electrically connected to the scanning system are arranged on the carrier; In a tensioned steel wire ruler capable of correcting the material properties of a steel wire system, the above-mentioned problems are solved as follows by the present invention, namely, the tensioned steel wire system is provided with limited permanent magnet markings created by magnetization. a scanning system, which is provided with an operating element and received by the carrier, which is connected to the carrier frequency bridge circuit and adjusts the scanning system perpendicular to the plane of the tensioned steel wire system. , by aligning the front surface of the scanning system to a location that is invariant to variations in magnetic permeability (electrical center), i.e. a location that is unaffected by permanent magnet marking measurement technology. , a pulse-limited modification of the tensioned steel wire system, the permeability of which is advantageously changed by 510% compared to the average value of the permeability of the steel wire system created by demagnetization. .

Its value must be at least large enough to compensate for the very possible difference between the geometric center and the electrical center, and in the case of overlap overruns on the marking, in the carrier frequency bridge circuit, the value must be The device or indicator is adjusted so that neither positive nor negative deflections occur. With this basic adjustment of the tensioned steel wire ruler, the inspection of the measuring object is almost free from the Δ/ur effect.
