Unified Soil Classification System
The so-called Unified Soil Classification System (USCS) determines whether a vehicle carrying a load is able to drive across a certain piece of land. The classification is expressed in figures, one for the vehicle and one for the soil. The figure for the vehicle, the Vehicle Cone Index ( VCI ), has no dimension and is based on various factors, e.g. soil accessibility, soil pressure and the ratio between engine capacity and weight of the vehicle. The Cone Index (CI) represents the soil figure. This figure can be determined by means of a cone-penetrometer. A comparison of both indexes shows the suitability of the terrain for driving over.
Whether you need to determine the penetration resistance or the cone vehicle index of a soil, the penetrologger with built-in data logger with GPS will provide you the ultimate in field soil structure data collecting. Accurate sensors, a bi-partite probing rod, a cone, the depth reference plate, a communication port and a GPS system all contained in a water-resistant housing make the penetrologger complete. The penetrologger is fitted with an adjustable LCD screen for a clear display, also in direct sunlight. The logger is battery operated (5ea. MH AA size rechargeable), comes with universal recharging adapter. The standard kit, among other items, contains: the penetrologger, a cable for the connection of the penetrologger to the PC, a manual for the penetrologger and for the PC-software, the software itself, a battery charger, probing rods, various cones, cone check and bag of tools.

Prior to going into the field, a measuring plan is programmed on a PC or on the logger itself. Name your project, the required number of measurements, the type of cone, the speed of penetration, etc. After programming, a cone is screwed on to the 32 inch (80 cm) probing rod, which is connected with 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 a very accurate depth measurement.
The measured resistance to penetration and the GPS coordinates are stored in the internal logger of the penetrologger. Optional is the possibility of soil moisture measurement with an external soil moisture sensor (1 moisture measurement per penetration).
