Ramsey(原“美国拉姆齐”) 皮带机拉线防护器

Thermo Fisher Scientific 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

Universal mounting plate

Secondary flag alarm

Complete hook-up accessories including: cable, clamps, standoffs, lights

NEMA 4 and NEMA 9 Alarm Light
