The Ramsey™ Conveyor Protection Switches Feature:
Thermo Scientific Ramsey Belt Misalignment Switch (Run off Switch)

  • Used to monitor position and tracking of conveyor belts
  • Mounts on conveyor structure and adjusts so roller arm is the proper distance and angle from outside edge of the belt
  • If belt drifts out of alignment, it contacts the roller actuator arm, which rotates the actuation shaft and triggers the belt misalignment 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
  • Pull cable rotates the actuating arm and actuating shaft if force is applied
  • Switch enters a tripped and locked position at a 20° rotation
  • Actuating shaft has two cams; each cam simultaneously actuates an independent SPDT micro-switch for shutdown and alarm signals

Thermo Scientific™ Ramsey™ Tripper Position Switch

  • Often used to indicate the position of a tripper on a conveyor with multiple discharge points
  • Can be used anywhere a heavy duty limit tripper switch with physical activation is needed

Note:
Agency Approvals: Models with CSA approval for Class II; Division 1 and 2; and Groups E, F, and G are available
