Ramsey IDEA Belt Scale System

Categories : Conveyor Belt Scales and Monitoring Equipment

The Thermo Scientific* Ramsey IDEA belt scale system provides basic rate information and totalization functions in processes involving non-critical or lower value materials with an accuracy of ±1%.

The belt scale system consists of three major elements: the weighing assembly measures the weight of material on the belt, the belt speed sensor and electronic integrator integrates the output signals from the scale module and speed sensor to arrive at a rate of material flow and the total material passed over the scale.

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
