Our Ramsey Belt Scale

This system is specifically designed for high accuracy or basis of payment applications requiring certification by government and regulatory agencies. It is extremely accurate to within 0.125% and is the most widely certified belt scale in the world. It has received its Certificate of Conformance in the United States as issued under the National Type Evaluation Program (NTEP) of the National Conference on Weights and Measures. Outside of the U.S., it is certified by OIML and EEC Class I standards. It represents the world standard of accuracy and performance for loadout, inventory monitoring and fee-holder type applications.

A safety pull cable is attached to the actuating arm of the 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.

This tramp metal detector minimizes lost production by providing an economical and reliable means to protect expensive crushers, conveyors and other process equipment from damage by tramp metal. It can detect all types of metallic scrap, including bucket teeth, manganese steel mantles, bore crowns, bar scrap chains, tools and more. Because the Thermo Scientific Ramsey Oretronic IV is insensitive to materials with high magnetic permeability and electrical conductivity, it can be used in applications where conventional metal detectors produce an unacceptable false alarm rate. It is designed especially for belt conveyors moving coal, iron pellets, minerals, aggregates and other bulk materials.
