The weighing module is actually a device that converts the quality signal into the measured point signal output. The sensor first needs to consider the environment in which we actually work. This is very important for us to choose the weighing module correctly. This is related to him. Whether we can work properly and his life problems, we must choose carefully.

First: characteristic error. Caused by the device itself, including DC drift values, incorrect bevels, or non-linear bevels. After all, there is a gap between the ideal transfer function and the real features of the device.

Second: Weigh module application error. That is, errors 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, incorrect placement of the transmitter, etc. Error.

Third: dynamic error. Sensors for static conditions have a strong damping, so the response to changes in the input parameters is slow, and even a few seconds can respond to temperature step changes. Some weigh modules with delay characteristics produce dynamic errors when responding to fast changes. Response time, amplitude distortion, and phase distortion all cause dynamic errors.

Fourth: Insertion error. It is the error caused by changing the measurement parameters when a sensor is inserted in 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.

Fifth: environmental error. The use of weighing modules can also be affected by environmental factors such as temperature, vibration, vibration, altitude, and chemical volatilization. These factors can easily cause the environment.
