INDOPOL - Rotor Weigher

Introducing the world’s most convenient
ONLINE CONTINUOUS SOLUTION
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.
