SECTION S | SOIL
MEASURE OF THE AXIAL FORCE APPLIED TO THE SPECIMEN
Three different equipments are available to measure the axial
force applied to the specimen:
load proving rings (manual readings)
load cells (automatic readings)
submersible load cells (automatic readings and no friction
effects)
LOAD PROVING RINGS
Mechanical equipment for manual reading. In order to avoid any
overload damage, an electrical safety device is supplied to stop the
loading process when the maximum capacity of the ring is reached.
Technical details, other models and accessories see p. 573

ACCESSORY
S374
STEM MECHANICAL BRAKE DEVICE
It keeps the max. reached value on the dial gauge and
allows the manual zero setting.
ELECTRIC STRAIN GAUGE LOAD CELLS
Electrical equipment for automatic reading. The load cell must be
connected to the automatic data acquisition system mod. S334
(see p. 559). Cable, connector and device to fix the load cell to the
triaxial frame are supplied.
Rated output: 2 mV/V nominal
Accuracy: 0.1%
Models Capacity
S337-31 2.5 kN
S337-35 5 kN
S337-32 10 kN
S337-33 25 kN
S337-34 50 kN
SUBMERSIBLE LOAD CELLS
Submersible electrical equipment for automatic reading.
The submersible load cell must be placed inside the cell and connected
to the automatic data acquisition system mod. S334
(see p. 559).
It is made of high quality materials. It is a sealed waterproof device
with an excellent resistance to lateral forces.
It guarantees no friction effect of the ram. It is strongly recommended
when high accuracy in testing is required.
It must be equipped with the loading ram mod. S337-21.
Rated output: 2 mV/V nominal
Accuracy: 0.1%
Non-linearity: 0.05%
Models Capacity
S337-02 3 kN
S337-03 5 kN
S337-04 10 kN
S337-05 25 kN
