Abstract

PURPOSE: To obtain a correct measured value by finding the reverse matrix of a characteristic matrix showing the state of interference caused between axial components in advance and carrying out correction arithmetic operation using this reverse matrix by an analog arithmetic circuit.
CONSTITUTION: Such coefficients K11 - K13, K21 - K23, and K31 - K33 that Ax=K11Vx+K12Vy+K13Vz, Ay=K21Vx+K22Vy+K23Vz, and Az=K31Vx+ K32Vy+K33Vz are hold are found, where Ax, Ay, and Az are the X-axial component, Y-axial component, and Z-axial component of an external force operating on an operation point and Vx, Vy, and Vz are voltage values obtained according to a bridge circuit consisting of plural resistance elements. Then the values of the terms in the right members of the relational expressions are calculated by using analog multipliers 101 - 109 and the right members are added by using analog adders 111 - 113 to obtain the detected values Ax, Ay, and Az from the arithmetic results.
