(1) Rated load: the maximum axial load that the sensor can measure within the specified technical index range. But in actual use, generally only 2/3~1/3 of the rated range is used. 
(2) Allowable load (or safe overload): the maximum axial load allowed by the load cell. Overwork is allowed within a certain range. Generally 120%~150%.
(3) Ultimate load (or limit overload): the maximum axial load that the load cell can bear without making it lose its ability to work. This means that the sensor will be damaged when the work exceeds this value.
(4) Sensitivity: the ratio of the output increment to the applied load increment. Typically mV of rated output per 1V of input.
(5) Nonlinearity: This is a parameter that characterizes the accuracy of the correspondence between the voltage signal output by this sensor and the load.
(6) Repeatability: Repeatability indicates whether the output value of the sensor can be repeated and consistent when the same load is repeatedly applied under the same conditions. This feature is more important and can better reflect the quality of the sensor. The description of the repeatability error in the national standard: the repeatability error can be used to determine the maximum difference (mv) between the actual output signal values of the three measurements at the same test point at the same time as the nonlinearity.
(7) Lag: The popular meaning of hysteresis is: when the load is applied step by step and then unloaded in turn, corresponding to each load, ideally there should be the same reading, but in fact they are consistent, the degree of inconsistency is measured by the hysteresis error. represented by an indicator. The hysteresis error is calculated in the national standard as follows: the difference between the arithmetic mean of the actual output signal value of the three trips on the same test point and the arithmetic mean of the actual output signal value of the three upstrokes (mv).
(8) Creep and creep recovery: It is required to check the creep error of the sensor from two aspects: one is creep: the rated load is applied without impact for 5-10 seconds, and 5-10 seconds after loading Take readings and then record the output values sequentially at regular intervals over a 30-minute period. The second is creep recovery: remove the rated load as soon as possible (within 5-10 seconds), immediately read within 5-10 seconds after unloading, and then record the output value at certain time intervals within 30 minutes.
(9) Allowable operating temperature: specifies the applicable occasions for this load cell. For example, the normal temperature sensor is generally marked as: -20℃ - +70℃. High temperature sensors are marked as: -40°C - 250°C.
(10) Temperature compensation range: This indicates that the sensor has been compensated within such a temperature range during production. For example, the normal temperature sensor is generally marked as -10°C - +55°C.
(11) Zero temperature influence (commonly known as zero temperature drift): It characterizes the stability of the zero point of the sensor when the ambient temperature changes. Generally, the unit of measurement is the drift generated in the range of every 10 °C.
(12) The temperature effect of the output sensitivity coefficient (commonly known as coefficient temperature drift): This parameter characterizes the stability of the output sensitivity of the sensor when the ambient temperature changes. Generally, the unit of measurement is the drift generated in the range of every 10 °C.
(13) Output impedance: Under the rated technical conditions, the resistance value of the sensor output S+ S- [I+ I-]
(14) Input impedance: the resistance value of the excitation end of the load cell, E+ E- [V+ V-]
(15) Insulation resistance: the insulation resistance value between the circuit part of the sensor and the elastic beam, the bigger the better, the size of the insulation resistance will affect the performance of the sensor. When the insulation resistance is lower than a certain value, the bridge will not work properly.
(16) Recommended excitation voltage: generally 5~12 volts. Because the regulated DC power supply in the general weighing instrument is 5 or 12 volts.
(17) Allowable maximum excitation voltage: the maximum power supply voltage that the sensor can withstand, and the maximum excitation voltage is not recommended. 
(18) Cable length: The length of the cable configured by the manufacturer when leaving the factory. It is best not to increase and decrease arbitrarily.
(19) Sealing protection grade IP67: dustproof and waterproof performance index of the load cell. (end)
