If the pressure exceeds the limit of the load cell, the overload will be bad?

Load cells (also called load cells or weighing cells) are designed with certain overload capacity in mind, but exceeding their maximum range or overload limit may indeed lead to damage. Specifically, if the force applied to the sensor exceeds its design norm, the following situations may occur:

Permanent deformation: the material may exceed its elastic limit, resulting in permanent deformation. In this case, the sensor will no longer be able to measure the force accurately.

Damage of internal components: Excessive force may damage the sensitive components inside the sensor, such as strain gauges, leading to sensor failure.

Electrical fault: in extreme cases, overload may also cause damage to the electrical part of the sensor, such as solder joint fracture or circuit board damage.

Therefore, when using the load cell, we should ensure that the measured force is within its range and does not exceed its recommended maximum overload value. If it is expected that there may be a greater overload risk, we can choose a sensor with a higher overload protection level or take appropriate mechanical measures to limit overload. At the same time, regular calibration and maintenance are also necessary measures to ensure the normal work of the load cell.
