| Specifically designed for operations where economy and ease of installation are important considerations, the Ramsey IDEA Belt Scale System is ideally suited for applications in processes involving either non-critical or lower value materials. It provides basic rate and totalization functions that can be used for control and/or production output monitoring. The Ramsey IDEA Belt Scale System continues Thermo Scientific’s long-standing tradition of providing high quality, reliable and innovative bulk weighing products to the process industries. Its patented design is the result of many years of experience in thousands of belt scale applications around the world.
How the System Operates
The Ramsey IDEA Belt Scale System consists of three major elements: the weighing assembly, the belt speed sensor, and an electronic integrator. The weighing assembly consists of either one or two modules, depending on conveyor width. Compact and designed to attach to the conveyor’s stringers, the modules support the weigh idler and measure the weight of material on the belt. The speed sensor is mechanically connected to the conveyor’s large diameter tail pulley and generates a stream of pulses. Each pulse represents a unit of belt travel. The frequency of the pulse stream is proportional to belt speed. The electronics integrate the output signals from the scale module(s) and speed sensor to arrive at a rate of material flow and the total material passed over the scale. The electronics also function as the system’s power supply and incorporate all the features that allow calibration, operation and diagnostics for the entire system.
The Scale Modules
The patented Ramsey IDEA Belt Scale is unlike any other single-idler scale. It consists of either one or two completely assembled Ramsey 10-101R Scale Modules. Each module contains a load cell in a pivotless assembly with factory installed and calibrated overload protection. The system’s single module version is for use on conveyors with belt widths up to 914 mm (36 in). This scale module mounts to a support beam that spans the conveyor stringers. The system’s dual module version is for use on conveyors with belt widths up to 1,524 mm (60 in). The weighing assembly consists of two identical modules with right and left side steel mounting brackets. Each bracket mounts directly to the conveyor stringer with two bolts.
Each Module features:
- Factory installed and calibrated overload protection
- Pivotless design with no linkages to introduce errors
- No moving or wearing parts to cause potential maintenance problems
- Compact design for easy installation and alignment
- No place for material to build up and cause measurement errors
- Identical scale modules fit on any belt width and are interchangeable
