WebThe penetrometer is fitted with a 1/4 inch (6.36 mm) plunger. When i press the penetrometer into the scale until the dial reaches 1 Kg/Cm2 i get a reading of approximaetly 1.75 kg. when i calculate the pressure -. Plunger area: (0.635/2)^2*pi = 0.317cm2. Force: 1.75*10 = 17.5 N. I get a value of about 550 kPa, which is way too high. WebThe Pocket Penetrometer was developed by Soiltest Inc for use by field engineers to check the visual classification of soils. The readings of the Penetrometer were compiled from several thousand unconfined compression tests of silty and clay-like soils. 2 Operation 2.1 The red ring on the barrel of the Penetrometer holds the maximum reading of the
