Abstract
The manufacturing method includes: performing testing of samples having the same configuration as the torque measuring device to be manufactured to find a coil balance Cthat is a ratio (R1×R3)/(R2×R4) of a product R1×R3 of resistance values R1 and R3 of one pair of opposite sides of the four sides of a bridge circuit, and a product R2×R4 of resistance values R2 and R4 of another pair of opposite sides of the four sides, and a temperature change rate Vof output voltage Vo of a sensor portion, and acquiring a relationship X between the coil balance Cand the temperature change rate Vfrom the test results; and measuring the resistance values R1, R2, R3, R4 of the four sides to find the coil balance Cto find the temperature change rate Vfrom the relationship X for the torque measuring device to be manufactured.
