06.15 SA Penetrologger

Categories Soil , In-Situ Soil Physical Research

The penetrologger is a versatile instrument for in situ measurements of the resistance to penetration of the soil.

The cone is screwed on the probing rod, which is connected with a quick coupling to the force sensor on the penetrologger. Now the cone is pushed slowly and regularly into the soil.
The depth reference plate, which is on the soil surface, reflects the signals of the ultrasonic sensor, which results in very accurate depth measurement.
The depth reference plate is also used to reflect the signals which are used to control the penetration speed.
The measured resistance to penetration and the GPS coordinates are stored in the internal logger of the penetrologger.

The penetrologger can be applied in the agricultural as well as in the civil engineering sector:

General soil science research;
Foundation technology;
Checking whether or not the soil is suitable for agricultural;
Research into (expected) growing conditions for plants;
The detection of compacted (possibly impermeable) sub-soil layers;
Research into poor growing conditions of for instance trees in the city or in parks;
Checking artificially-made compactions;
Checking the suitability of soils for carrying vehicles or pedestrians.
