瓶子標籤驗證
應用挑戰
食品和飲料行業通常需要驗證產品上的標籤，包括瓶子上的標籤。亮面背景的存在是標準直反式感測器難以解決的一個問題。
解決方案
Banner的Q3X多功能、堅固耐用的雷射對比度感測器(包括背景消除），對於需要忽略的固定背景的對比度應用是理想之選。在此應用中，Q3X背景消除感測器可以檢測帶有和不帶有標籤的瓶子之間的對比度差異，從而實現可靠的標籤偵測。Q3X具有長達50 mm的工作距離，可以很好地檢測出對比度的微小變化。
在Q3X偵測到棕褐色標籤時，強度讀數增加并觸發數位輸出，表示存在酒瓶標籤。如果標籤不存在，則強度讀數降低，輸出保持關閉。此外，Q3X可以忽略大於60 mm的物件，在這種情況下，閃亮的金屬導軌（可能會令其他感測器發生錯誤觸發）將被忽略。
Q3X具有直觀的設定，兩個觸覺按鈕位於顯示螢幕下方，可在設定和操作期間為使用者提供明確的回饋。金屬製作、帶有雷射標記的堅固外殼使得感測器適用於許多環境，甚至是高壓沖洗或可能存在切削液和切削油的環境。提供不同款式的支架來滿足許多應用要求。
