HONEYWELL 05701-A-0329卡件,05701-A-0329參數(shù)說明
腹板張力系統(tǒng)中使用的定義
標(biāo)稱載荷Fnom是稱重傳感器所承受的載荷尺寸和校準(zhǔn)，即靜止
負(fù)載和測(cè)量中的最大測(cè)量負(fù)載方向Fext=擴(kuò)展范圍。在Fnom和Fext之間測(cè)量精度可能會(huì)下降。
靈敏度定義為輸出信號(hào)的差異在標(biāo)稱負(fù)載和空載之間。
精度等級(jí)定義為最大偏差，以及表示為標(biāo)稱條件下靈敏度的百分比
負(fù)載這包括線性偏差、滯后和重復(fù)性誤差。
HONEYWELL 05701-A-0329卡件線性偏差是與輸出值零和之間繪制的直線標(biāo)稱荷載，與標(biāo)稱荷載相關(guān)。
滯后是輸出信號(hào)的最大偏差從零到標(biāo)稱負(fù)載的循環(huán)中的相同負(fù)載，以及回到零，與標(biāo)稱負(fù)載下的靈敏度相關(guān)。
滯后與循環(huán)成比例。重復(fù)性誤差定義為最大偏差在相同條件下重復(fù)讀數(shù)之間。
它表示為以下條件下靈敏度的百分比：標(biāo)稱載荷。溫度依賴性是與標(biāo)稱負(fù)載下的靈敏度。
零點(diǎn)漂移定義為輸出信號(hào)中的漂移當(dāng)稱重傳感器上沒有負(fù)載時(shí)。
靈敏度漂移定義為標(biāo)稱載荷，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.
