邦納傳感器的使用說明
Setting the cutoff distance 截止距離的調節 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.) 用一個小起子調節螺絲旋鈕,調節截止距離,直到其臨界值且綠色指示燈狀態變化。(如果指示燈沒有on,則為背景超過了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. 重復以上過程,在黑暗目標,用更遠的距離進行感應,調節截至距離直到其在兩個刻度的中間位置。 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,被檢測物體的感應距離必須滿足以下條件:該物體必須要在傳感器的額定增益之內。 The excess gain curves on page 1 show excess gain vs. sensing distance for 200 mm and 2 m cutoffs. 該增益曲線如*頁所示,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,截止距離在透鏡到檢測物體的距離約150毫米,2米時,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。檢測低反射率的對象, 下面的兩個指標是可行的, 即使針對近程反射背景。 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).
