Extended Reading
Performance indicators of weighing sensors
The performance of a weighing system can be measured by indicators such as linearity, hysteresis, repeatability, and creep.
Linear:Indicates the consistency between the actual output of the system and the theoretical straight line. As shown in the figure, when linear errors occur, the output of the system is correct at no load and full load, but the input-output points between these two points are inconsistent with the ideal state. Linear error is the maximum difference between the theoretical straight line and the actual output curve.
Lag:Indicates the degree to which the input-output curve of the system does not coincide during loading and unloading.
Repeatability:Indicates the degree of inconsistency in the system's output for several consecutive weighing of the same weight during the loading or unloading process. Usually expressed as the percentage of the total output that is the difference between the minimum output and the maximum output of the system under the same loading condition.
Creep:The characteristic of a system that bears a constant weight at a certain temperature, and the output changes over time due to the mechanical deformation of the elastic material of the sensor.
　
2、 The Principles and Differences of Three and Four Wire Transmitters

Different wire systems refer to various outputs that are analog DC current signalsWeight transmitterThe difference in its working principle and structure, rather than just referring to the wiring form of the transmitter.
The term 'several wire system' came into existence after the birth of two wire transmitters. This is the result of the widespread application of electronic amplifiers in instruments. The essence of amplification is an energy conversion process, which cannot be separated from power supply. Therefore, the first to appear were four wire transmitters; Two wires are responsible for the power supply, and the other two wires are responsible for outputting signals that are converted and amplified (such as voltage, current, etc.). The emergence of the ddz - ii type electric unit combination instrument, a four wire transmitter with a power supply of 220v. ac and an output signal of 0-10MA. DC, has been widely used, and its presence can still be seen in some factories.
In the 1970s, China began producing DDZ III electric unit combination instruments and adopted the International Electrotechnical Commission (IEC) standard for analog signals used in process control systems. The instrument transmission signal adopts 4-20MA.DC, and the contact signal adopts 1-5V.DC, which is a signal system that uses current transmission and voltage reception. By using 4-20MA.DC signals, on-site instruments can achieve a two wire system. However, due to limitations, the two wire system was only used on pressure and differential pressure transmitters at that time, while temperature transmitters still used the four wire system. The product range of two wire transmitters in China has greatly expanded and their application fields are also increasing. At the same time, the majority of transmitters imported from abroad are also two wire systems.
　
The essence of the two wire system is that the power supply and load are connected in series, with a common point. However, the signal connection and power supply between the on-site transmitter and the control room instrument only use two wires, which are both power and signal wires. Due to the signal starting point current of 4MA.DC, the two wire transmitter provides static working current for the transmitter. At the same time, the instrument electrical zero point is 4MA.DC, which does not coincide with the mechanical zero point. This "active zero point" is conducive to identifying faults such as power outage and wire breakage. Moreover, the two wire system also facilitates the use of safety barriers, which is conducive to safety and explosion protection.

As shown in Figure 1, the two-wire power supply is 24v.dc, the output signal is 4-20MA.DC, and the load resistance is 250 ω， The negative line potential of the 24V power supply is the lowest, which is the signal common line. For smart transmitters, the fsk keying signal of the hart protocol can also be loaded onto the 4-20MA.DC signal.
