MEASURE OF VOLUME CHANGE
In order to measure volume changes during test, two solutions are
proposed:
Double burette apparatus
Standard or automatic volume gauge with displacement
transducer or dial gauge.
S358
DOUBLE BURETTE VOLUME CHANGE APPARATUS
It is composed by two measuring burettes which are placed inside a
perspex tube and connected directly to a reverse valve system.
A by-pass valve is also included.
Capacity: 200ml
Accuracy: 0.2ml
Dimensions: 230x270x860 mm
Weight: 5 kg approx.
S338N
VOLUME GAUGE
The unit consists of a metallic air/water
interface. It measures the water volume
changes inside the sample. It has to be used
with linear strain transducer, or dial gauge.
Capacity: 100 ml
Accuracy: better than 0.1 ml.
Dimensions: 180x180x240 mm
Weight: 4.7 kg approx.
Easy de-airing of bottom and top chambers.
No measuring device and mounting block
are included (see accessories).
S338-01 KIT
AUTOMATIC VOLUME GAUGE
The unit consists of a 100 ml metallic
air/water interface. A change valve box
provides unlimited capacity.
Easy de-airing of top and bottom
chambers. Displacement transducer,
coupling pliers and mounting device
are not included (see accessories)
Capacity : unlimited
Accuracy: better than 0.1 ml
Dimensions:
360x270x210 mm
Weight:
7.6 kg approx.

ACCESSORIES for VOLUME GAUGES
S336-12 Displacement transducer 25 mm travel TYPE “A”
S336-16 Displacement transducer 25 mm travel TYPE “B”
Note: Technical data for all transducers: see p. 549
S335-15 Universal coupling pliers to hold the transducer/dial
gauge. It fits all Matest displacement transducers and
dial gauges (from Ø 8 mm to 20 mm).
S338-05 Mounting device of the universal coupling pliers mod.
S335-15 to fix the displacement transducer/dial gauge
to the volume gauge.
S359
THREE-CELLS CONSOLIDATION FRAME
It is used to apply a constant axial load to three specimens, at the
same time. It performs an anisotropic consolidation stage reducing
the consolidation testing times.
It is made of a resistant metallic structure which accepts up to 3
triaxial cells for specimens dia. 38 mm up to 100 mm, and it is
provided with centering plate cells.
Load can be applied through an hanger with two different ratios:
- Ratio 1:1 (directly), maximum load for each cell: 50 kg
- Ratio 5:1 (by means of a lever), maximum load for each cell: 250 kg
Dimensions: 2300x400x1800 mm
Weight: 150 kg approx.
ACCESSORIES
S273 KIT Set of slotted weights 50 kg
S377 Dial gauge, 25x0.01 mm suitable for specimens of
max. dimensions 50x100 mm
S379 Dial gauge, 50x0.01 mm suitable for specimens of
max. dimensions 70x140 mm
As an alternative:
S336-12 Displacement transducer 25 mm travel
S336-14 Displacement transducer 50 mm travel
Note:
The volume gauge has to be
used with linear strain transducer
which must be connected to the
automatic data acquisition system
mod. S334 (see p. 559) or mod.
S301-05 ( see p. 544).
