Abstract

PURPOSE: To realize a high-accuracy measurement of load, by securing a parallel insertion of the reference resistor to one side of the bridge circuit forming the distortion gauge and thus giving a correction to the measurement through a comparison between the reference level of the output voltage caused by the above reference resistor and the sampling value right before measurement.
CONSTITUTION: The voltage of the power source 3 is applied between the terminals (a) and (b) of the bridge circuit 2 formed with the distortion gauge 1, and thus the output voltage between the terminals (c) and (d) is amplified 4. Then the reference resistor 5 is inserted between the transmission lines la and lc of the bridge circuit via the relay contact 6a. And then the output voltage of the amplifier 4 when the contact 6a is closed after the installation and control of the detector is stored in the momory 10 in the form of the reference value Est and by the control circuit 7. After the start of the detector, an intermittent closure is given to the contact 6a when the output voltage of the amplifier 4 is lower than the prescribed level, and thus the output voltage of the amplifier 4 is sampled 12. Then the compensation factor is calculated 13 from the sampling value and the reference value. In such way, the output voltage Ex of the amplifier can be corrected according to the sampling value right before the detection and when the load is detected.
