Thanks to electronic scales weighing load cells can

Life, people always say , everyone who wants to lose weight crush , just weigh weight , there will be a determination to lose weight . The weigh is inseparable from electronic scales, electronic scales Why can then weigh this depends on a load cell inside presence .Electronic weighing scales Crankshaft Position Sensor can be said that the most important one of the components , in addition to the load cell and then is IC, mainly for two core components , the load cell itself is only an analog signal , when a weight of pressure to the load cells at when the elastic element in Crankshaft Sensor will produce a deformation about this change in the load change of about 1mm .When deformed , attached to the elastic element above minor resistance strain gauges will be pulled up and bent wire cut , totaling four resistors, in accordance with the principle of a Wheatstone bridge , when the resistance strain gauge will move up and bending resistance to two a change in direction , a negative direction is a positive direction , the value is read by our this difference , the amount of difference between the different type of deformation , but this is linearly proportional to , of course, there are some small errors.This error is because of the location and materials and other influential patch , we call it non-linear . So when a platform scale factory calibration and calibration we all need , from two considerations, one is the output , one is non-linear .This is the original strain gauge output , this output signal is very weak , thenormal situation , so take this signal processing IC , so that users can read people understand Kg and pound figure.
