Mass flow

This  radiometric measuring system from RGI measures delivery volumes, throughput and mass flow without contact and can be used on all known conveyor systems. A major advantage of our measuring technology is the reproducibility and freedom from maintenance that have been stable for years. Recalibrations are therefore not necessary.

Since  the delivery rate is measured contactlessly and without moving components, there is no influence on the throughput measurement due to dirt, incrustations, weather influences, fluctuations in the belt tension or varying bulk densities.

Product specification

Evaluation unit for single-channel radiometric belt weigher

Description

MACON 21  is a microprocessor-controlled controller for determining the conveying capacity of a belt or a belt conveyor in combination with a single-channel radiometric belt scale.

MACON 21  consists of a small computer that uses calibration coefficients from the beam attenuation and a belt speed signal to calculate the conveying capacity and outputs it as a current signal in the range 0 / 4-20 mA.

Optionally,  the operation can also be carried out with an IPC / laptop that can be connected to another interface.

With  the small computer control, all operational parameters are accessible via menu control in conjunction with a four-line LC display and can be quickly adapted to the respective measurement situation.

Thanks  to the detector geometry of the radiometric measuring section, it is possible to reliably measure the delivery rate even when the occupancy profile changes.

The  decrease in the activity of the radioactive emitter used is automatically compensated for in accordance with the half-life.

The  system is calibrated using sample weighing with the conveyor belt running, using a mechanical belt weigher or a truck / track weigher.

All  inputs and outputs are galvanically isolated from the computer and are protected against reverse polarity or interference (EMC) by a comprehensive protective circuit.

The  measured value is output as an analog 0 / 4-20mA signal with 10-bit accuracy (better than 0.5% of the selected measuring range) and any scaling.
