CAT NO: DIDACTICNLE-Export-114003
Digital Direct Residual Shear Apparatus.
Used to determine the resistance to shearing of all types of soil
specimens both consolidated and drained, undisturbed or remoulded
samples. The machine can accommodate specimens dia. 60, 100 mm, and
square 60x60, 100x100 mm. The apparatus is equipped with a control
closed loop motor with epicycloid reducers. At the beginning of each
test, the machine performs an automatic and complete internal check, a
position reset with the elimination of all possible positioning errors
and all pauses. The input of all the test patterns is achieved by the
interaction of the keyboard and the alphanumeric display with
self-memory, thus granting infinitesimal resolutions in short times. All
data are input and stored when the machine is in stand-by, without
affecting the specimen under test with quick machine setting.
Possibility to fix maximum excursion of the shear box, so as to
interrupt automatically the test. It is possible to input a different
return speed (residual shear) in relation to the one used for the shear
test, thus allowing a quick playback to select the residual shear test,
saving a lot of time. For determining the direct shear strength of soils
on specimen size 60mm x 60mm x 25mm Features :RS 232 output for
connection to PC Display of both speed and displacement with 0.00001 mm
resolution Shear speed between 0.00001 to 9.99999 mm/minute Max shear
effort: 5000 N possible on the whole speed range Possibility of direct
vertical load, or with a lever arm ratio 10:1Max vertical direct load:
500N; with lever arm: 5500NDisplay and pilot lamps to signal any bad
functioning and alarms Box group mounted on ball track with high quality
anti friction system Read value results are immediate and of extreme
accuracy Extremely easy and practical use, not requiring qualified
staff.Shear box, hollow punch and tamper are not included in the
standard supply and have to be ordered separately Power supply: 230 V
A.C. Single Phase 50Hz.
