感測食品包裝和輸送
肉類包裝輸送系統的檢查有一些獨特的挑戰。在此應用中，肉類準備妥當後就被放置在深色塑膠盤上。在塑膠盤包裝和貼標籤之前，它們會沿著一系列白色輸送帶移動。在這種多輸送帶的配置中，感測器必須置於每個輸送帶上，以便在食物塑膠盤移動的過程中偵測到它們。
應用挑戰
食品在準備交貨和展示的過程中經過各個不同的包裝階段。自動化設備和感測器必須準確一致執行，同時能耐受惡劣的沖洗環境。
描述
該應用的感測特性簡單而獨特：感測器直接位於白色、高反光的背景上方，且必須偵測不同紋理、較暗、較低對比度的物體。EZ-BEAM T18固定距離感測器是理想的解決方案。它有清晰的偵測截斷值，對顏色變化不敏感 - 對一定範圍內存在的物體發出信號，但會略背景。感測器的直角外殼讓連接電線與安裝組件平行共存，讓造型精巧低調。感測器位在輸送帶上方，居於忽略背景的高度，同時還可偵測到食物塑膠盤，因此無需要進行範圍調整。
QD型號T18感測器的保護等級值為IP69K，而且像EZ-BEAM系列中的許多感測器一樣，可以承受頻繁、嚴酷的沖洗考驗。
特色產品
T18系列一體圓柱式感測器
完全環氧樹脂封裝的圓柱式感測器可在直流和交流電源電壓下工作，並可承受惡劣的感測環境。
