When measuring, the correct force is applied to the outer side of the strain E-shaped beam portion of the sensor (i.e., a strain gauge affixed to the middle, with a beam of white plastic cover arm) and the outside edges to form a shear force in the opposite direction, i.e., in the middle of strain beam bending necessary changes can occur under stress, strain beam side by another force can not have a barrier.

This sensor is a group of half bridge strain gauge, using the method can have the following three:
1, using a sensor with the external resistance to form a full bridge measurement, the range of a sensor range: 50kg. External resistance     requirements are higher.
2, the use of two sensors to form a full bridge measurement, measuring the range of two sensors and: 50kgx2=100kg
3, the use of four sensors to form a full bridge measurement, measuring range of four sensors and the range: 50kgx4=200kg
