起重機電子式超載限製器工作原理

電子式超載限製器克服了機械式超載限製器體積大、重量大

、精度低等缺點，並可以隨時顯示起吊物品的重量，因而近年來在起重機上廣泛應用。它主要由載荷傳感器、電子放大器
、數字顯示裝置、控製儀表等組成一個自動控製係統。

應變筒和應變環用彈性較好的合金鋼製成，表麵貼有４片電阻應變片
，並構成電橋回路，其作用是將載荷（力信號）debianhuazhuanhuanweidianxinhaodebianhua。qizhongjidiaozhongwushi，zaihechuanganqideyingbiantongshouzaihezuoyongfashengbianxing，tiezaishangmiandeyingbianpianyesuizhibianxing
