Thermo Scientific Ramsey

Thermo Scientific Ramsey manufactures industrial in-motion weighing, monitoring and inspection equipment used for process control and production control in a wide variety of industrial applications. Products include weighbelt feeders, belt scales, metal detectors, sampling systems, level indicators, conveyor safety switches. Below is an embedded copy of the Thermo Scientific / Ramsey Bulk Weighing and Monitoring Catalog. You can download a copy at the TECO website here.

Impact Weighers - Principle of Operation

Impact Weigher
Impact weighers are in-line instruments used for weighing of bulk materials. They are designed to measure the force generated by the impact of flowing material on a sensing plate. This force creates a mechanical deflection as it impacts the plate. This deflection is measured by a sensor and converted into an electrical signal. That signal is then processed by an electronic controller, which displays the flow rate and total weight.

Impact Weighers

Impact weighers are designed so that the impact plate can only move horizontally. This means that from the total impact force “Fi,” only the horizontal component “Fh” is measured. In the diagram above, “Fv” is ignored. This guarantees that changes in the weight of the sensing plate, due to material build-up or sensing plate wear, will not affect the zero or accuracy of the system.

Advantages:
  • Easy installation in difficult process environments 
  • Measurement is not affected by changing the impact point on the sensing plate • Build-up on the sensing plate cannot influence the zero point
  • High reliability and low maintenance 
  • Mechanical damping system absorbs shocks and damps vibration
  • Sensor allows some overload withoutdamage to the system
  • Sensor is located in a dust-tight enclosureexternal to the process stream 
  • Operates accurately in pulsating or surging flows
