Abstract
PURPOSE: To improve sensitivity and precision at the time of low torque by changing torque between a high-sensitivity load cell and low-sensitivity load cell by using spring force of a coil spring provided inside of the load cell as to a dynamo motor.
CONSTITUTION: In main load cell body 1 installed on earth 2, axial hole 3 is made and in hole 3, coil spring 4, load cell bearing axis 5 and high-sensitivity load cell 6 are fixed; and high-sensitivity load cell 6 has sensing part 6a brought into contact with axis part 7a of flange 7, which comes in contact with sensing part 8a of low- sensitivity load cell 8. Therefore, at the time of torque (lower than coil spring 4), force F is transmitted to high-sensitivity load cell by way of low-sensitivity load cell 8 and flange 7 and at the time of high torque, force F is transmitted to low- sensitivity load cell 8 without clearance l between main load cell 1 and flange 7, so that load cells can be changed over according to a load.
