Cone Penetrometer - Digital (Semi-Automatic)

STANDARDS COMPLIANCE :

• COMPLIED AS PER BS 1377-2, CEN ISO/TS 17892-6, 17892-12

Application :

• Semi-Automatic Digital Penetrometer apparatus is used to determine the moisture content at which clay soils pass from a plastic to a liquid state and is used also for the determination of undrained shear strength.

Operation :

• Semi-Automatic Digital Penetrometer for Liquid Limit is complete with automatic controller, which automatically releases the plunger by a magnetic device, complete with micrometer vertical adjustment and adjustable electronic timer and free fall time. The penetrometer is equipped with a digital timer which can be set to the standard 5 second free-fall timer or to some other setting for customized tests. When engaged the timer will allow the needle to free fall into the sample for the specific time interval and then lock the needle from advancing while providing a direct reading of the test results.

• 320 g weight should be added to the 30° angle cone to get a total weight of 400 g for the shear strength test.
  The electronic timer allows the user to set up and read the fall time of the needle during testing.

• Semi-Automatic Penetrometer for Liquid Limit is complete with automatic controller, which automatically releases the plunger by a magnetic device, complete with micrometer vertical adjustment and adjustable electronic timer and free fall time.

• Automatic Penetrometer Timer Unit
• 30° Penetration Cone
• Sample Cups, 3 pcs. Aluminum, °55 mm ° 35 mm

Ordering Information :

• Mirror is available for easy cone height adjustment and should be ordered separately.

Dimensions (cm):

• 20°30°50

Weight (kg) :

• 10

Power Supply :

• 220 V, 50–60 Hz, 1 ph

• The penetrometer has a cast iron base with leveling screws, digital penetration measurement gauge 0.01 mm precision, release button and automatic zeroing.
• It is provided with lead screw gear arrangement, leveling screws, and Spirit level.
• The head can be clamped at any desired height. A rack and pinion pointer assembly provides fine adjustment of the cone tip to sample. It incorporates a clutch mechanism which makes reading of penetration and subsequent resetting a simple and accurate operation.
