偵測玻璃面板
應用挑戰
大型彩色玻璃面板生產過程透過滾淪的傳送。為了定位，必須在面板通過時檢測面板的邊緣。感測器必須安裝的應用中可能具有挑戰性，因為工廠照明可能會導致感測不可靠。這個應用的另一個難點是缺乏固定的背景。
解決方案
WORLD-BEAM QS18帶背景消除功能的可調場感測器具有增強的抗日光燈干擾能力，使其能夠可靠地檢測玻璃面板的邊緣，儘管周圍有工廠燈的存在。
使用背景消除來解決背景條件變化這個難題。設定點距離由用戶透過一個簡單的多圈旋鈕調整來設定。感測器將忽略超出設定截止距離的物體。
在使用具有背景抑制功能的QS18可調場感測器的應用中，物件相對於感測器的方向是關鍵。物件必須垂直於感測器面行進，以確保可靠的偵測。使用背景抑制時要記住的另一件事是需要物件和背景之間的最小間隔距離。在這個應用中，玻璃面板與工廠天花板之間有足夠的距離。
