Position: This page describes the applications,Design features and weighbridge advantages of the Belt Scale System which is from Ramsey.
Series 20 Belt Scale System monitors feed to crushers, mills, screens and other processes with an weighing accuracy of ±0.5%, even in the harshest applications. The Ramsey Series 20 lets you monitor production output and inventory, or regulate product loadout, while providing vital information for the effective management and efficient operation of your business.
Belt Scale Applications
* Chemical plants
* Asphalt plants
* Mines
* Cement mills
* Coal preparation plants
* Paper mills
* Gypsum mills
* Sand and gravel operations
* Coal-fired power plants
* Ore benefication processes
* Rail loadouts
Designed for general in-plant belt conveyor weighing applications in the most demanding industrial weighing environments, Thermo Electron Corporation’s Ramsey Series 20 Belt Scale System lets you control feed rates to crushers, mills, screens and other processes with incredible accuracy. It can monitor production output and inventory, or control product loadout, while providing vital information for the management and operation of your business.
The Ramsey Series 20 combines the proven reliability of the Ramsey 10-20 Single Idler or 10-22 Dual Idler Weighbridge and the Ramsey 60-12 Belt Speed Sensor with the power and versatility of the advanced electronics in the Ramsey Micro-Tech 2000 Series or the Ramsey Micro-Tech 3000 Series of electronic integrators.

Easy Installation
Easy to install, indoors or out, on fixed or portable conveyors, the rugged construction of the Ramsey Series 20 allows for installation in the harshest applications at a variety of locations.
The Weighbridge
Rigid and rugged, the Ramsey 10-20 and 10-22 Weighbridges remain permanently aligned within the conveyor frame. This one-piece, drop-in style weighbridge is completely assembled at the factory and is quickly and easily installed and aligned properly on the conveyor. It is designed to provide additional stiffening and support to minimize conveyor deflection.
Both the single and the dual-idler models offer three-point suspension and employ trunnion-type, frictionless pivots. These sealed units are impervious to vibration, moisture and product build-up, which eliminates problems commonly associated with knife edges and bearings.
The Belt Speed Sensor Thermo’s Ramsey 60-12 Digital Belt Speed Sensor is the most reliable and accurate speed-sensing device ever developed for belt scale service. Direct-coupling the sensor to the conveyor tail pulley, snubbing roll, or a large diameter return roller ensures an accurate belt-travel readout. No wheels ride on the belt, which eliminates problems related to material build-up and slippage.
Weighbridge Advantages
* No moving or wearing parts
* Precision strain-gauge load cell applied in tension to guarantee load cell alignment and accuracy
* Total deflection of idler(s) less than 0.102 mm (0.004 in)
* Slim profile to minimize material build-up
* Optional counterweighted carriages for light belt loading applications Belt Speed Sensor Advantages
* Rugged, cast-aluminum housing suitable for outdoor installations
* A.C. pulse generator means no brushes to adjust or replace Performance Guarantee On factory-approved installations, we warrant that the Ramsey Series 20 Belt Scale System will weigh and totalize to a value within ±0.5% of the test value when calibrated against a known test weight, chain, or Thermo’s standard electronic weighing calibration.
