A4H124-24TX交換機(jī),A4H124-24TX英文說(shuō)明設(shè)置包裹增益為了能夠在顯示器上顯示實(shí)際的卷筒紙張力，卷筒紙張力和必須確定稱(chēng)重傳感器上測(cè)得的力。這個(gè)比率是一個(gè)稱(chēng)為包裹增益的比例因子。包裹增益取決于紙幅在測(cè)量輥上的包裹角度和紙幅的方稱(chēng)重傳感器。因此，包裹增益取決于實(shí)際安裝。這將提供：T（張力）=包裹增益??FR（稱(chēng)重傳感器測(cè)量方向上的腹板張力力）有兩種方法可以確定腹板張力與負(fù)載上測(cè)得的力之間的比率單元格，
A4H124-24TX交換機(jī)通過(guò)懸掛重量或計(jì)算。帶懸掛重量（菜單懸掛重量）將一根繩索準(zhǔn)確地沿著腹板路徑纏繞，并施加已知重量應(yīng)用的已知重量模擬實(shí)際腹板張力和電子測(cè)量施加的重量對(duì)稱(chēng)重傳感器產(chǎn)生的力。當(dāng)腹板張力（T）和相應(yīng)的測(cè)量力（FR）已知時(shí)張力電子裝置計(jì)算T/FR比，并將該值存儲(chǔ)為包裹增益。當(dāng)卷筒張力應(yīng)用于輥時(shí)，張力電子設(shè)備通過(guò)以下方式計(jì)算卷筒張力：將測(cè)得的稱(chēng)重傳感器上的力乘以包裹增益。在掛重程序之后，可以通過(guò)張力電子裝置計(jì)算包裹增益可在EnterWrapGain菜單中找到按計(jì)算（菜單EnterWrapGain）包裹增益是一個(gè)比例因子，對(duì)應(yīng)于腹板張力（T）和作用在稱(chēng)重傳感器測(cè)量中的腹板張力的力分量（FR）方向包裹增益范圍為0.5-20。如果嘗試將包裹增益設(shè)置在此范圍之外，則顯示屏上將顯示消息“WrapGainTooLow”或“WrapGainTooHigh”。包裹增益可設(shè)置為分辨率0.01。描述包裹增益計(jì)算原理的示例：Set Wrap GainTo be able to present actual web tension on the display, the ratio between web tension andmeasured force on the load cell must be determined.This ratio is a scaling factor called Wrap Gain.The Wrap Gain depends on the web's wrap angle on the measuring roll and the orientation of theload cells. Therefore, Wrap Gain depends on the actual installation.This gives:T (tension) = Wrap Gain ??FR (force of web tension in load cell measuring direction)There are two ways to find out the ratio between web tension and measured force on the loadcells, by Hanging weights or by Calculation.? With hanging weights (Menu HangWeight)String a rope that follows the web path exactly and apply a known weight.The applied known weight simulates the actual web tension and the electronics measuresthe resulting force on the load cells caused by the applied weight.When both web tension (T) and the corresponding measured force (FR) are known thetension electronics calculates the ratio T / FR and stores the value as Wrap Gain.When web tension is applied to the roll the tension electronics calculates web tension bymultiplying the measured force on the load cells with the Wrap Gain.After the hanging weight procedure the wrap gain calculated by the tension electronics canbe found in the EnterWrapGain menu. ? By calculation (Menu EnterWrapGain)Wrap Gain is a scaling factor which corresponds to the ratio between Web Tension (T) andthe force component (FR) from web tension that is acting in the load cell measuringdirection.The Wrap Gain range is 0.5 - 20. If you try to set the wrap gain outside this range,
