標稱(chēng)載荷Fnom是稱(chēng)重傳感器所承受的載荷尺寸和校準，即靜止
負載和測量中的最大測量負載方向Fext=擴展范圍。在Fnom和Fext之間測量精度可能會(huì )下降。
靈敏度定義為輸出信號的差異在標稱(chēng)負載和空載之間。
精度等級定義為最大偏差，以及表示為標稱(chēng)條件下靈敏度的百分比
負載這包括線(xiàn)性偏差、滯后和重復性誤差。
HONEYWELL 05701-A-0329卡件線(xiàn)性偏差是與輸出值零和之間繪制的直線(xiàn)標稱(chēng)荷載，與標稱(chēng)荷載相關(guān)。
滯后是輸出信號的最大偏差從零到標稱(chēng)負載的循環(huán)中的相同負載，以及回到零，與標稱(chēng)負載下的靈敏度相關(guān)。
滯后與循環(huán)成比例。重復性誤差定義為最大偏差在相同條件下重復讀數之間。
它表示為以下條件下靈敏度的百分比：標稱(chēng)載荷。溫度依賴(lài)性是與標稱(chēng)負載下的靈敏度。
零點(diǎn)漂移定義為輸出信號中的漂移當稱(chēng)重傳感器上沒(méi)有負載時(shí)。
靈敏度漂移定義為標稱(chēng)載荷，不包括零點(diǎn)漂移。
Definitions used in the Web Tension Systems
Table A-1. Definitions
Nominal load, Fnom, is the load for which the load cell is
dimensioned and calibrated, i.e. the sum of the stationary
load and the maximum measured load in the measuring
direction.
Fext = Extended range. Between Fnom and Fext some
decline in measurement accuracy may be experienced.
Sensitivity is defined as the difference in output signal
between nominal load and no load.
Accuracy class is defined as the maximum deviation, and
is expressed as a percentage of the sensitivity at nominal
load. This includes linearity deviation, hysteresis and
repeatability error.
Linearity deviation is the maximum deviation from a
straight line drawn between the output values of zero and
nominal load, related to the nominal load.
Hysteresis is the maximum deviation of the output signal at
the same load during a cycle from zero to nominal load and
back to zero, related to the sensitivity at nominal load.
The hysteresis is proportional to the cycle.
Repeatability error is defined as the maximum deviation
between repeated readings under identical conditions.
It is expressed as a percentage of the sensitivity at
nominal load.
Temperature dependence is the drift in %/K related to the
sensitivity at nominal load.
Zero point drift is defined as the drift in the output signal
when there is no load on the load cell.
Sensitivity drift is defined as the drift in the output signal at
nominal load, excluding the zero point drift.
