詳細信息| 詢價留言品牌：美國DAKOTA NDT 型號：/BT2-DL 輸入通道數：1 應力測量范圍：根據自選探頭 分辨率：+/-0.0001毫米 可測樣品高度：根據自選探頭 外形尺寸：63.5 x 165 x 31.5 mm 分辨率：+/-0.0001毫米 可測樣品高度：根據自選探頭 美國DAKOTA NDT 螺栓應力測試儀BT1-DL
BT1-DL 使用超聲波精確測量緊固件的伸長、時間（納秒）、載荷、應力和%應變。采用先進的超聲波皮射技術 ，能快速地測量出螺栓緊固后的應力和應變 ，
具有使用方便、顯示直觀、 便于攜帶等特點。
螺栓應力測試儀以其*的構思、 強大的功能和測量廣泛的應用于航空航天、 衛星制造、電力設備、 建筑橋梁和石油化工等領域。
簡介
DAKOTA NDT BT1-DL 螺栓張力監視器
當螺母和螺栓在負載下緊固在一起時，擰緊螺母的動作會增加施加在螺栓上的力，從而導致伸長。
通過使用超聲波，螺栓張力監視器不受溫度、摩擦或電阻因素的影響，這些因素會影響標準扭矩測量技術的精度.
BT1-DL螺栓張力監視器的精度在0.0001毫米（0.0001英寸）內。
使用儀表的USB接口以及可選的關閉附件，可以編程為在施加適當的負載時自動停止擰緊過程。
