Thermo Scientific* Ramsey conveyor protection switches protect your equipment, prevent accidents and reduce unscheduled shutdowns.
The run off switch and safety pull cord switch are now available with network addressable modules. Ramsey conveyor safety switches are used for position information, control signals, and to identify potentially hazardous situations with your process equipment. They utilize a rugged, heavy-duty design and are built to last.
Details :
Thermo Scientific Ramsey Belt Misalignment Switch (Runoff Switch)
- Used to monitor the position and tracking of conveyor belts
- Mounts on the conveyor structure and adjusts so the roller arm is the proper distance and angle from the outside edge of the belt
- When a belt drifts out of alignment it contacts the roller actuator arm which rotates the actuation shaft, causing the belt misalignment switch to send an alarm signal
Thermo Scientific Ramsey Safety Cable Pull Switch (Pull Cord Switch)
- Used as an emergency shutdown device for conveyors or other equipment
- Meets OSHA and MSHA requirements for safety shutdown devices
- Safety pull cables are attached to the actuating arm of the switch
- When force is applied to the pull cable it rotates the actuating arm and actuating shaft
- At a 20° rotation the switch enters a tripped and locked position
- The actuating shaft has two cams inside the housing; each cam simultaneously actuates an independent SPDT micro-switch for shutdown and alarm signals
Thermo Scientific Ramsey Tripper Position Switch
- Heavy-duty limit switch
- Often used to indicate the position of a tripper on a conveyor with multiple discharge points
- Can be used anywhere an extremely heavy duty limit switch with physical activation is needed
Agency Approvals: Models with CSA approval for Class II, division 1 & 2, groups E, F, and G are available
