Introducing the worlds most convenient
                                             for weighing of flour, powders & bran

  • A rotor is located in the rotor weigher which is driven by a constant speed three - phase induction motor.
  • The product to be weighed is fed to the centre of the rotor and then accelerated to a peripheral speed of approximately 10 m/s.
  • As the product flows through the rotor the coriolis force, or compound centrifugal force, is created as a reaction force. This coriolis force is absorbed through a spring element below the rotor and detected by means of two magnetic flux induction sensors.
  • The coriolis force is completely proportional to the mass flow.
  • Material-specific characteristics such as, i.e., different moisture levels, flow characteristics or friction do not influence the measurement as errors.
  • Pulse time spacing of both inductive sensors is detected accurately by the separate evaluating electronic system.
  • The momentary throughput in (kg/h) is then calculated from these times, indicated and compared with two adjustable limit values.
  • An electronic integration device then uses the output signal to calculate the total weight fed through the rotor balance system and display the result on a resetable summation device. In addition, kg pulses are available for the remote counters and yield calculators.
  • The evaluation electronic system can be installed at any distance from the weigher.
  • The system can be supplied in a wall-mounted cabinet or suitable for control panel installation.
  •  A preselection counter for setting the required throughput as well as a 0 (4) - 20 A analogue output of the momentary throughput can be supplied as an option for control and registration.
