Details•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 a 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.
•Depending on the application and the expected resistance to penetration, various cones can be connected to the probing rods.
•Optional is the possibility of soil moisture measurement with an external soil moisture sensor.
