The weighing sensor can be said to be one of the most important parts of a electronic scale

The weighing sensor can be said to be one of the most important parts of electronic scale, weighing sensor and then is in addition to IC, mainly for the two core elements, weighing sensor is itself an analog signal, when a weight to the weighing sensor at the top, in the sensor element elastic will produce a deformation, the change changes in the load YLE Engine Water Temperature Sensor at about 1mm. When the deformation, strain is stuck on the elastic element above meter fine wire delete will bend and try for, a total of 4 sheet resistance, according to the principle of Wheatstone bridge, when the resistance strain gauge and try for the resistance to bending when the 2 directions, one is the positive direction to a negative direction, we read his numerical is this difference, the difference of different deformation, YLE Car Temperature Sensorbut this is linearly proportional to the number of, of course there are some small error. This error because of the location and the material is affected, it is called nonlinear. So when a platform balance before we all need calibration and calibration, considered from the 2 aspects, one is the output, one is nonlinear. This is the primary output of strain gauge, the output signal is very weak, the normal condition, so the IC to the signal processing, allows the user to read to understand Kg and pound figure.
