What are the precautions for replacing the force sensor

Force transducer: no matter it is electronic scale or electromechanical scale, it can be used only after it is verified and qualified after replacing the transducer.

For the electromechanical coupling scale with S-shaped sensor installed in the second transmission link, we should pay attention to whether the length of the connecting rod after reinstallation of the sensor is consistent with the original length, and we should ensure that the first transmission lever is horizontal and the link is perpendicular to the first transmission lever at a 90 degree Angle. If there is a deviation, it will affect the accuracy and sensitivity of the scale. If the length of the link is too long, there will be a "scale" phenomenon oh, too long not so short? There will be a "small scale" phenomenon. At the same time, it should be noted that the link is in the state of free suspension, not friction with other objects, so as not to affect the sensitivity of the scale.

Force transducer

The premise of force sensor replacement is that the axis of applied force and the force axis of the sensor coincide, we should know that with the increase of rated load, the output of the sensor microvolt/fractional signal decreases. Point often overlooked by people, thought was positively proportional relationship between, actually not, replace the sensor should be as same as the original sensor payload, if want to change the load bigger, must look of electronic weighing instrument can adjust the, if not, then don't change, or to the original load, because for large load sensor output microvolt/dividing signals become smaller, not full scale output, display, dial the code adjustment can not reach the purpose, and so cannot be used, if can be adjusted, so the question is, is not big.

In the debugging of electromechanical scale after replacing the sensor, it should be carried out according to the weighing indicator instruction on the basis of accurate debugging of mechanical scale.
