Precautions for load cell replacement – Turck

Create Date: 2024-8-30 12:03:23|Source: TURCK/TURCK

The condition for the replacement of the load cell is that the axis of the applied force coincides with the axis of the force of the sensor, and we should know one thing, that is, with the increase of the rated load, the microvolt/indexing signal output by the sensor decreases.

                            Precautions for load cell replacement – Turck

Regarding the electromechanical scale with the S-shaped sensor installed in the second transmission linkage, we should pay attention to whether the length of the connecting rod after reinstalling the sensor is the same as the original length, and we should also ensure that the first transmission lever is horizontal and the linkage and the first transmission lever are straight at an angle of 90 degrees. If there is a deviation, it will affect the accuracy and sensitivity of the scale. If the length of the link is too long, it will show the phenomenon of "big scale", too long is not so short? The phenomenon of "small scales" will appear. It should also be noted that the linkage is in a free suspension state, and it cannot be rubbed against other objects, so as not to affect the sensitivity of the scale.

This point is often neglected, thinking that there is a proportional relationship between the two, practice is not, the replacement sensor should be as much as possible and the original sensor load is the same, if you want to change the load a little larger, you have to see if the weighing instrument of the electronic scale can be adjusted, if you can't adjust, then don't change, still to the original load, because the microvolt / indexing signal output of the sensor with a large load becomes smaller, can not be full-scale output, display, dial adjustment can not achieve the purpose, so that it can not be used, if it can be adjusted, then the problem is not big.

Whether it is an electronic scale or an electromechanical scale, it can only be used after replacing the sensor and passing the verification. In the debugging of the electromechanical scale after replacing the sensor, it should be carried out according to the weighing display instrument manual on the basis of the accurate debugging of the mechanical scale.
