MuST FBG Deformation Sensor
Long-gauge 可變形傳感器堅固且易於安裝
描述
MuST FBG 變形傳感器是將靜態或動態距離變化轉換為預應力光纖布拉格光柵反射波長變化的傳感器，可通過SMARTEC讀數單元進行測量.
傳感器由有源和無源部分組成。活動部分包含測量光纖並測量其兩端之間的變形，將其轉化為光纖布拉格光柵的波長偏移。無源部分對變形不敏感，用於將傳感器連接到讀取單元。在傳感器的無源部分，可以安裝一個鬆散的光纖布拉格光柵用於溫度檢測和補償.
這些傳感器採用單端，雙端和鏈接配置。使用我們的讀數單元，可以在同一通道上連接多達7個全量程溫度補償傳感器（或者最多4個溫度補償+ 4個）。傳感器採用E2000-APC連接器或用戶規格終止.
傳感器可以快速方便地安裝，而不會影響施工進度。它們可以直接嵌入混凝土和砂漿或表面安裝.
