邦納傳感器的使用說(shuō)明
Setting the cutoff distance  截止距離的調(diào)節(jié)  Using a small screwdriver in the adjustment screw , adjust the cutoff distance until the threshold is reached and the green light indicator changes state.（If the indicator never comes ON, the background is beyond the maximum sensing cutoff and be ignored.）  用一個(gè)小起子調(diào)節(jié)螺絲旋鈕，調(diào)節(jié)截止距離，直到其臨界值且綠色指示燈狀態(tài)變化。（如果指示燈沒(méi)有on，則為背景超過(guò)了zui大傳感距離，且被忽略）  Note the position of the rotating cutoff position indicator at this position.  注意，旋轉(zhuǎn)的該位置就是截止位置。  Then repeat the procedure, using the darkest target, placed in its most distant position for sensing. Adjust the cutoff so that the indicator is midway between the two positions.  重復(fù)以上過(guò)程，在黑暗目標(biāo)，用更遠(yuǎn)的距離進(jìn)行感應(yīng)，調(diào)節(jié)截至距離直到其在兩個(gè)刻度的中間位置。  Sensing Reliability 傳感器可靠性  For highest sensitivity, the sensor-to-object distance should be such that the object will be sensed at or near the point of maximum excess gain. 
為了獲得高靈敏度，被檢測(cè)物體的感應(yīng)距離必須滿(mǎn)足以下條件：該物體必須要在傳感器的額定增益之內(nèi)。   The excess gain curves on page 1 show excess gain vs. sensing distance for 200 mm and 2 m cutoffs.  該增益曲線(xiàn)如*頁(yè)所示，額定增益的距離為200mm到2m之間。  Maximum excess gain for a 200 mm cutoff occurs at a lens-to-object distance of about 150 mm, and for a 2 m cutoff ,at about 500 mm. 
zui大額定增益為200毫米時(shí)，截止距離在透鏡到檢測(cè)物體的距離約150毫米,2米時(shí),約500毫米。  The background must be placed beyond the cutoff, at about 500 mm. Following these two guidelines makes it possible to detect objects of low reflectivity, even against close-in reflective backgrounds.  其背景都必須放在截止面以外約500毫米。檢測(cè)低反射率的對(duì)象, 下面的兩個(gè)指標(biāo)是可行的, 即使針對(duì)近程反射背景。  Background reflectivity and placement 背景反射率和安置  Avoid mirror-like backgrounds that produce specula reflections. False the sensor’s light more strongly to spouse will occur if a background surface reflects the sensor’s light more strongly to the near detector(R1) than to the far detector(R2).
