Non-linearity refers to the phenomenon that the output voltage signal of a force transducer has a non-linear relationship with the applied force. Ideally, the output voltage of a force transducer should be proportional to the force applied. The greater the force, the higher the output voltage. However, in practice, due to various factors, there is often a non-linear relationship between the output voltage and the force.

Non-linear error is an important indicator of the performance of the force sensor, which indicates the degree of deviation between the actual output value of the force transducer and the ideal output value. Usually, the nonlinear error is expressed as a percentage, that is, the difference between the actual output value and the ideal output value as a proportion of the ideal output value.

There are many reasons for non-linear error, such as: manufacturing errors in the load cell, wear and tear during use, incorrect installation, and so on. In order to minimise non-linear errors, force transducers need to be accurately calibrated and adjusted. During calibration, the force transducer is loaded and measured using standard weights or other standards, and the difference between the actual output value and the ideal output value is compared. Based on the calibration results, the zero point and range of the force transducer can be adjusted to achieve optimum measurement accuracy and stability.

In addition to non-linear errors, force transducers may also have other errors, such as hysteresis errors and repetition errors. These errors will affect the measurement accuracy and reliability of the force transducer, so it is necessary to carry out regular inspection and maintenance in the process of use.

The nonlinearity of the force transducer refers to the nonlinear relationship between its output voltage and the force applied. In order to reduce the nonlinear error, it is necessary to carry out accurate calibration and adjustment of the force transducer, and pay attention to the maintenance and repair in the process of use.
