ROS-2D防偏開(kāi)關(guān)可固定在輸送機(jī)縱梁的頂部或底部，動(dòng)作臂距皮帶邊緣大約25到75mm。通常安裝在皮帶兩側(cè)距頭部或尾部滾筒0.3到2米的地方。 

皮帶跑偏后，迫使動(dòng)作臂偏離，觸動(dòng)DPDT報(bào)警微動(dòng)開(kāi)關(guān)。如果繼續(xù)偏停到停機(jī)觸點(diǎn)，觸動(dòng)另一組觸點(diǎn)，輸送機(jī)就會(huì)保護(hù)性停機(jī)。

Xuzhou Ramsey（徐州拉姆齊） 皮帶機(jī)跑偏保護(hù)裝置

 offers a variety of components for monitoring conveyors and other bulk material handling equipment, including the Ramsey Pro-Line Safety Cable Pull Switch. These devices monitor operating processes for potentially hazardous conditions and activate an alarm when they occur. This helps to keep your personnel safe, your equipment from being damaged, your time from being wasted, and your profits from becoming losses.

For Emergency or Normal Shut-Off

A safety pull cable is attached to the actuating arm of the Ramsey Safety Cable Pull Switch and terminated at fixed mounts at either end of a conveyor. Force applied to the pull cable at any position causes the actuating arm to move into a tripped-locked position and activates an alarm from one DPDT or two SPDT micro-switches, alerting equipment circuits of the stop condition. This will stay locked until manually reset by the reset lever.

Options
