METHOD AND DEVICE FOR MEASURING THE BI-DIRECTIONAL FORCE ACTING ON THE TENSOMETRIC BRIDGE WITH A COMPENSATION OF THE SYSTEMATIC AND QUASI-DYNAMIC ERRORS

摘要

2. A circuit for the measurement of a two-directional force acting on an extensometric bridge with compensation of statistical and quasi-dynamic errors, characterised in that the output of the extensometric bridge (1) is connected to the input of the analogue line (2), to which the output of a voltage divider (3) is connected, and further the output of the analogue line (2) is connected to a comparative circuit (4), to which a step generator (5) is connected, and the output of the comparative circuit (4) is connected to the input of a decade counter (7) via a gating circuit (6), and the output of the decade counter (7) with a register (8) constitutes a coupling loop and is connected to the measured value display circuit (9), and the decade counter (7) is connected to the control circuit (10).IMAGE
