Dynamic penetrometric tests in a portable device.
The DPM30 penetrometer allows exclusively continuous dynamic penetrometric tests to be performed. For the dynamic tests, the penetrometer is equipped with a 30 kg (66 pound) hammer with a 200 mm (7.87 inch) stroke, operated by a hydraulic motor. It is driven by a motor-pump unit, where the motor can be either electric (220v or 110v) or a petrol engine. A hydraulic extractor is used to extract rods, lining tubes and samplers. The penetrometer is controlled via a pedal-operated distributor. The hydraulic connections on the various components use quick connectors. Reliability proven by hundreds of units operational within Italy and around the world.
The DPM30 penetrometer can use the following, as well as its standard equipment:
• a sampler for taking soil samples with limited disturbance, guaranteeing improved ability to interpret the penetrometric data;
• removable bits;
• lining tubes for DP tests.
