Thermo Ramsey Conveyor Protection Switches
Thermo Scientific Ramsey Belt Misalignment Switch (Run off 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
