WEIGHTRAC: Measurement of mass flow on conveyor belts with radiometric measuring principle

In radiometric measurement, an isotope emits focussed gamma rays. The sensor on the opposite side of the conveyor belt receives the radiation.
The scintillator of the sensor converts the gamma radiation into signals, whose quantity is detected and evaluated. Because gamma rays are attenuated when penetrating matter, the detector can calculate the mass flow on the basis of the change in intensity.
The advantages
  • Wear and maintenance free due to non-contact measurement
  • Accurate determination of the flow rate of solids, very simple setup and commissioning
  • Easy installation of the measuring frame on the conveyor belt

Function

Radiometric measurement is based on focused gamma rays, i.e. radiation, emitted by an isotope. The sensor, located on the opposite side of the conveyor belt, receives this radiation. The detector of the sensor converts the gamma radiation into signals, the number of which is recorded and evaluated.

Series

Mounting

The radioactive source is mounted on one side of the container and the detector on the opposite side. You can slide WEIGHTRAC 31 into the measuring frame from both sides to mount it.

Connection

A three-core installation cable with PE conductor is required for power supply. The 4 ... 20 mA current output is connected with standard two-wire cable.

Setup

Due to the measuring principle itself, there is no linear relationship between the pulse rate and the level. For that reason, an adjustment must always be carried out.
