Function
- 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.
THIS IS EVERY MILLERS PROFIT MACHINE!!
- Sealed dust-tight and maintenance-free system
- Low installation height, simple assembly
- Largely insensitive to vibrations
- Direct mass flow measurement
- Not dependent on friction, moisture and flow characteristics
- Patented, proven measuring system
Evaluation
- 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.
