As an international active and renowned manufacturer, supplier and service provider for devices, systems and systems for the contactless detection of various process parameters (e.g. density and humidity) mainly of bulk materials (e.g. coal and potassium salt) we want to offer our customers the most effective solutions for their processes.
The possible technical solutions are ultimately defined by analyzing the customer processes and the operating conditions on site. You can find out how these can look in this section.
In many industrial processes, the density - either the specific density or the bulk density - is required to infer other process parameters.
So you can use the density e.g. measure the concentration of a two-substance mixture or the solids content during transport through pipelines continuously in an ongoing process.
This principle is based on the absorption measurement.
The result is influenced by the average material density between the detector and the radiation source.
All parts that are in the measuring beam but do not change during operation are calibrated.
Since only the measuring medium changes, the density can be deduced perfectly.
It is important that this is the average density.
So you can infer from the measured value on different sizes:
● Specific density
● Solid concentration (coal, ore, salt)
● Mixing concentrations (acids, bases, sugar content)
An electromagnetic wave of length and energy, which also has hard X-rays, is weakened as it passes through matter according to its density.
In order to obtain such a simple radiation source, artificially produced radioactive metal or metal oxide is welded into a high-security stainless steel capsule that has been tested in many ways.
The radiation can penetrate the capsule wall so that the radioactive material can remain safely in the capsule forever.
A constant measuring path is necessary in order to be able to clearly conclude the density.
The easiest way to realise this is on a pipe, but this condition can also be achieved in a tank or bunker by constructive measures.
In any case, the measurement remains contactless: neither the radiation source nor the detector come into contact with the medium.
is an artificially generated radioactive material that is welded in a capsule, which is tested in a variety of ways (heat test with subsequent quenching in ice water, impact test, etc.).
Since the radiation goes in all directions from this source, it is installed in a lead container that leaves only a narrow channel open towards the receiver.
The channel can be closed for transport or work in the vicinity of the useful beam.
The best way to measure radiation is through a material that absorbs it strongly, that is, it has a high density.
The most effective method is by means of a scintillation crystal, which converts the radiation into flashes of light, which are amplified by a photomultiplier and can then be recorded electronically.
Special stabilizing electronics, which analyze the radiation spectrum and keep the shape constant, ensure that the measurement remains stable in the event of temperature fluctuations and despite aging.
The detector already delivers a digital signal, so the successor electronics only need the mathematical conversion and calibration.
The processor-controlled device offers a wide range of functions and application options.
Finally the determined density value is not only shown on the display, but can also be passed on in analog or digital form.
