Analysis of the causes of common errors in load cells

In everyday life, load cells are less common, but in some work equipment, it plays a big role. Some small partners may not know much about it. It is actually a device that converts the quality signal into a measurable electrical signal output. When the instrument is used for a long time, some troubles will inevitably occur. The load cell is no exception. The inevitable error will occur, so what is the cause of the error in our daily life? Below the weighing sensor manufacturers Xiaobian specifically for everyone to analyze the problem points.

1. Load cell application error: that is, the error caused by operation, including incorrect placement of the probe, incorrect insulation between the probe and the measurement site, errors in the purification process of air or other gases, transmitter Errors caused by various operational errors such as incorrect placement.

2. Characteristic error: It is caused by the device itself, including DC drift value, incorrect bevel or non-linear shape of the bevel. After all, there will be a gap between the ideal transfer function and the real feature of the device.

3. Dynamic error: The sensor for static conditions will have strong damping, so the response to the change of the input parameters is slow, and even a few seconds can be used to respond to the temperature step change. Some load cells have a delay function that produces dynamic errors in response to rapid changes in response. Response time, amplitude distortion, and phase distortion all cause dynamic errors.

4. Environmental error: The use of load cells will also be affected by environmental factors such as temperature, oscillation, vibration, altitude, and chemical volatilization. These factors are likely to cause environmental problems.

5, insertion error: because the insertion of a sensor in the system causes some changes in the measured parameters, resulting in errors. Using a transmitter that is too large for the system, the dynamic characteristics of the system will be slow, and the system will self-heat and load too much thermal energy, which will cause insertion errors.

The above are some points about the analysis of the error, I hope everyone can help, want to know more about the load cell related knowledge, you can contact us Ocean Sensing...

5. Insertion error: It is the error caused by changing the measurement parameters when a sensor is inserted into the system. Using a transmitter that is too large for the system, the dynamics of the system is too slow, and the system is self-heating with too much thermal energy, which can cause insertion errors.
