When operated in accordance to BS 1377-2, 1924-2, EN DD ENV1997-2, users of the fall cone penetrometer available from Hylec Controls can quickly measure physical sediment character and bottom dynamics such as erosion, transportation, accumulation.
The fall cone penetrometer offers a simple and accurate method for determining the un-drained shear strength and the sensitivity of both undisturbed and re-moulded clays. The relationship between the depth of penetration of the fall cone and the un-drained shear strength has been determined after many years of research. The fall cone penetrometer can also be used to calculate liquid limits.
This model of fall cone penetrometer (10-1480) features a base frame with a measuring arm that is adjustable in height by means of a threaded spindle. The measuring scale is 20 x 1mm and the plunger weighting is 28 grams. Also included is a control module to release the plunger after preset time period.
Four different fall cone penetrometers are available:
- 60 gram, 60 deg profile
- 80 gram, 30 deg profile
- 100gram,30 deg profile
- 400gram,30 deg profile
