What are the errors of the load cell

When selecting a load cell, the actual working environment must first be considered. The working environment can affect whether the sensor can work normally, the service life of the sensor, and even the reliability and safety of the entire weighing instrument. So what are the errors that the load cell will produce?

1. Characteristic error:

This kind of error is mainly caused by the device's own DC drift value, the incorrect slope or the non-linear shape of the slope. We should always hear the phrase "ideal and reality are very different", and the load cell is also Similarly, there is a certain gap between the characteristics of the ideal transfer function of the load cell and the true characteristics of the sensor.

2. Application error:

This error is mainly caused by the operation. The main reasons for this error are the installation error of the sensor, the incorrect insulation of the sensor and the measurement site, the error in the purification process of air or other gases and other errors caused by various wrong operations. .

3. Dynamic error:

 This error is mainly due to the strong resistance of the sensor under static conditions, so the response speed to the change of the input parameter is relatively slow, even a few seconds before it can be sensed.

4. Environmental error:

This error is because the load cell will also cause errors due to some external environmental factors such as temperature, wind, vibration, and altitude.
