Ramsey Switches

Gerrard & Associates is a worldwide distributor of Thermo Scientific's complete line of Ramsey Switches.

• 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 Tilt Switchs & Controls (Mercury )

• Actuated at 15 deg. from its vertical position due to marterial rise or plugged chute conditions
• Used for stacker reclaimers, radial stackers, high level for bins, vessels, high pile detector, and plugged chute applications.
• Availiable in standard rating and Class I & II, Fm Approved (X-Proof). Tilt switch controls available for standard and Class I & II, Fm Approved (X-Proof).
• (2) normally-open and normally-closed output

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

Thermo Scientific Ramsey GTR 130 Flow/No-Flow

Thermo Scientific Ramsey Series 60-200 Motion Monitor System

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

• Advanced technology inside the tilt probe replicates performance found in traditional mercury-based Thermo Scientific Ramsey Tilt Rugged, abrasion resistant tilt probes

• detects and monitors low/no-flow conditions of bulk solids in pipelines, ducts and air-slides and at transfer points of chutes, conveyor.
• Low-cost, non-invasive, microwave-based 
• real-time flow information allows you to monitor processes closely
• leads to increased reliability, higher quality end product, reduced downtime and fewer hazards to jeopardize operators and equipment.

Thermo Scientific Ramsey Model 60-23P Under Speed Switch

• Non-contacting, proximity-type detector provides longer life and lower operating costs
• Two-bolt mounting assures simple installation
• Single piece construction with no separate control unit
• Easy to set up and/or troubleshoot
• Rugged Housing: weather-tight, polyammide/fiberglass, sturdy, lightweight
• No moving parts and longer trouble-free life
• Alarm/Delay: 10-second delay while rotating equipment reaches operating speed
• Alarm to normal delay assures notification when speed drops below adjustable setpoint

Thermo Scientific Ramsey Microwave Point Level Detector

• Recommended for: Pressurized coal down comers, electro-static precipitator hoppers, and in fly ash, clinker and coal transfer chutes
