Sensitivity: The difference in the output signal of the sensor with or without rated load. The unit is expressed in mV/V. At present, the sensitivity of the vast majority of sensors is 2 mv/V or 3mv/V
Comprehensive error: According to OIML R60, the accuracy level in China is generally C3 level, with a division of 3000 degrees; 0.02% F.S rated output.
Repeatability: Under the same environmental conditions, the sensor is repeatedly loaded to the rated load and unloaded, and the maximum difference between the output points at the same load point during the loading process is the percentage of the rated output

Zero point output: also known as zero point balance, refers to the percentage of the sensor's output value to the rated output when unloaded under the recommended voltage excitation.
Temperature compensation range: The sensor uses its zero point and output within this temperature range to meet the corresponding technical specifications.
Working temperature range: The sensor will not produce permanent harmful changes in any of its performance parameters when used within this temperature range.
Zero output temperature coefficient: The zero balance change caused by changes in environmental temperature, generally expressed as a percentage of the rated output caused by the zero balance change for every 10 ℃ change in temperature.
Rated output temperature coefficient: The change in rated output caused by changes in ambient temperature, usually expressed as a percentage of the rated output change caused by every 10 changes in temperature.
The weight of numerous parameters in sensors----accuracy
Accuracy: Determine the comprehensive error of the weighing sensor using the maximum error of six indicators: nonlinearity, hysteresis error, repeatability error, creep, zero temperature additional error, and rated output temperature additional error, represented by 0.02, 0.03, and 0.05, respectively. Within 0.03 is the C3 accuracy level, while within 0.05 is the D1 level. The common accuracy levels are C3>C3D>D1. The higher the accuracy, the more expensive the unit price, the lower the error, and the higher the accuracy.
illustrate
Z6FC3Sensor, with a range of 200Kg and an error of plus or minus 0.02%. The error can be calculated as 200 * 0.0002=0.04kg, which is positive or negative 40g. Analogy based on range.
