Soil non-kernel density meter Soil densitometer without kernel non-nuclear density gauge

The nuclear densitometer has been the most widely used method for measuring the density of geomaterials all over the world in the past forty years, because it has the advantages of accuracy, speed, economy and nondestructive testing that other testing methods do not have. Although nuclear devices are very safe to use and have never been hazardous to operators, because nuclear devices use isotope sources, and because of radiation concerns, many people want to obtain a means of accurately and quickly performing density and moisture tests without the use of isotopes, namely, nuclear-free technology. In the past three decades, dozens of nuclear-free density and humidity detection technologies have been commerciated, such as GeoGauge, EDG, PT and PQI in the past few years, each of which was called nuclear-free densitometer when it came out, and announced that it could replace the nuclear densitometer. So the concept of nucleeless densitometer represents different endogenies at different times.

The LRK-WH801 Soil densitometer uses high-frequency radio waves to measure the dielectric properties and density of compacting soil. In essence, high-frequency electromagnetic waves are measured in the same way as gamma rays. , only using high frequency electromagnetic wave is more secure, when electromagnetic wave through the soil, due to soil compaction degree of different, further affect the electromagnetic wave, electromagnetic wave that is through the soil, its will be affected by the corresponding phase and amplitude, and then we through comparing the standard attenuation parameter of soil module, can calculate the measured soil sample was wet Density and moisture content.

We use digital frequency synthesis (DDS) to ensure high precision wireless frequencies, and then measure the electromagnetic wave parameters between the steel pins inserted into the soil point-to-point to produce accurate measurements.

The specific measurement principle of LRK-WH801 is to measure the dielectric property and density of the compactified soil material through the radio high frequency between the electrodes, and compare the measured dielectric property with the "soil module". Mathematical algorithms are used to calculate dry/wet density, water content, and percentage compaction. The accompanying temperature detector can also increase the accuracy of the measurement.

1. Scope of application of soil non-nuclear density meter:

1). Excavation and backfilling construction;

2). Subways, basements and foundations;

3). Backfilling and ditches; Garbage;

Mainly suitable for clay and non-cohesive soil, can also be applied to lime or cement modified soil, gravel soil and other soil.

2. The following soil types are not suitable for measurement

1). In soils with high humus content, humus content is greater than 20%(V/V).

2). RCC.

3). The diameter of the vast majority of the soil (>=30%V/V) aggregate is greater than 15mm.

Note: If the diameter of aggregate is too large in the measurement of gravel soil, the accuracy of measurement may decrease. It needs to be confirmed and negotiated with the customer

It is efficient, easy to use and flexible. 2701-B uses electromagnetic sensitive technology for density testing, so no government licence or special training is required. Test data can be obtained within 2 seconds, saving time and cost. The 2701-B's memory can store about 1000 test data for later viewing, printing or downloading. The instrument has 30 buttons and a backlit 4 x 20 LCD, making it easy for the operator to see not only during the day but also at night. The 2701-B has a replaceable protective cover at its base. The protective cover provides thermal protection to the internal electronic components of the instrument and prevents wear at the bottom. The transport case of 2701-B contains a density reference block for standard density counting. The advanced software of 2701-B provides three test modes (continuous, average and segregation), making it more flexible and versatile. To make it easier to use, the software also provides automatic calculation functions (such as average density, compaction, voids, etc.). The test results of the instrument can be improved by density deviation compensation, slope adjustment or comprehensive calibration. 2701-B can be used either AC charger or DC charger
