Connection to compensate for undesirable offset measurement chain in continuous longterm measurement of deformation

摘要

The involvement of the compensation of the undesired offset of the measurement chain for continuous long-term measurement of deformation is characterized in that each of the sensors (1) of deformation including compensation sensor (6) deformations mounted on the measured object (2) is separately connected to the measuring channel (A1az M) and a compensation channel (When) s Wheaton measuring bridges (31 to M, 3k) and a / D converter (41az m, 4H) contained in the measurement module (B1) connected via a common measurement base (5) with the computer unit (7) to compensate for unwanted offset differential mode, and signal processing of the measuring channel (A1az M) and the compensation signal from the channel (If).
