4. Principles

4.1 Product Principles

The guided wave radar emits a high-frequency pulse wave to be transmitted along with the

detection component (steel rope or connecting rod). When it comes in contact with the

object to be measured, the pulse wave will be reflected and some of the energy will be

reflected as well due to the different dielectric constant of air and the material. The time

difference between the reflection wave and the emission wave can be used to calculate

the distance between the surface of the measured object and the guided wave radar level

sensor.

4.2 Bottom Tracking Probe Technology

4.2.1 Bottom Tracking Probe Technology

The product is equipped with a bottom tracking probe technology. This function is very

useful in increasing the sensitivity when the dielectric constant of the measured object is

low, such as the plastic particles, material fragments or that in the liquefaction container.

When the dielectric constant is 3~10, the bottom tracking probe function will be enabled

automatically as long as the echo signal is not detected. The measurement value is

calculated based on the dielectric constant recorded the last time. In this case, the

instrument accuracy depends on the stability of the dielectric constant.

If the dielectric constant of the media is lower than 3, the bottom tracking probe function

will be enabled all the time. Under this circumstance, you must input the dielectric constant

of the media, which is quite important for measurement.

4.2.2 Function Principle –Dual-Level Interface Measurement

The high-frequency micro wave pulse travels along the steel rope or the connecting rod.

When it reaches the media surface, a part of the micro wave pulse will be reflected.

Another part will penetrate the media in the upper layer (L1), and the second reflection will

take place on the interface between the upper (L2) and lower (L1) interface layers. The two

periods of pulse running will be calculated by the PCB inside the instrument, which also

outputs two levels.

※Measurement condition of dual-level interface:

Media on the upper layer (L2):

L2 must be non-conducting media. The dielectric constant of the media in L2 or the actual

distance towards the interface is known. The dielectric constant of the media in L2 must be

larger than 1.6. The media must be stable without change or mixture. Moreover, it must be

uniform. The minimum thickness of the media in L2 should be larger than 50mm

(1.97-inch), and L2 must be clearly separated from the lower layer (L1). In case of

emulsion phase or chipping layer, the maximum thickness should be 50mm (1.97-inch). It

should be without foam on the surface if possible, so it will get better measurement results.

Media on lower layer (L1):

The dielectric constant of L1 must be 10 larger than that of L2 at minimum, and the

conducting media is recommended. For example, if the dielectric constant of L2 is 2, the

dielectric constant of L1 should be 12 at least.

Gas layer (L3): It is the mixture of air or gas.

Output signal setting of dual-level interface measurement:

This instrument requires applying the setting in “level measurement”, which should be

applied in dual-level interface measurement. You may select dual-analog output version

and adjust the settings.
