S276-02 SHEARTRONIC DIGITAL SHEAR TESTING MACHINE WITH INCORPORATED DATA ACQUISITION SYSTEM AND PNEUMATIC VERTICAL LOADING DEVICE – FULLY AUTOMATIC HIGH PERFORMANCE

Category:

Sheartronic High Performance is an advanced system specifically designed to perform consolidation, direct and residual shear stages in a
fully automated way. The system is based on a pneumatic closed-loop system which along with a high-performance regulator guarantees an
automatic application of a vertical load up to 6000N, thus offering the unique possibility to reduce to the absolute minimum any form of manual
intervention (no need of dead weights or level arms).

TECHNICAL SPECIFICATIONS
Maximum horizontal force: 5000 N
Maximum travel: 20 mm
Shear speed: 0.00001 to 15.0000 mm/min
Maximum vertical load: 6000 N (more than 600 kPa on a 100 x 100
mm square specimen) applied by a pneumatic piston controlled by
a closed loop system with a 10 bar pressure transducer
Max air pressure supply: 10 bar
Max working air pressure: 8 bar

SHEARTRONIC SYSTEM INCLUDES:
S276-11 Shear frame with digital touch-screen microprocessor,
complete with pneumatic vertical loading device, shear
box case with adaptors, transducers supports.
S277-20 Load cell, electric, 3000 N capacity, complete with
cable (5000N cell available on request).
S336-11 Linear vertical transducer, 10 mm travel
S336-12 Linear horizontal transducer, 25 mm travel
S277-31 Firmware activating 3 connectors for basic data
acquisition
Technical specifications of the frame and firmware: see p. 536
Power supply: 230V 1ph 50-60Hz 200W
Dimensions: 1030x400x580 mm
Weight: 100 kg approx.

FIRMWARE
Similar to S276 KIT and S276-01 machines but with the new
possibility to identify directly on the consolidation curve the effects
of the primary consolidation. Sheartronic High Performance
automatically calculates the appropriate shear velocity to be
applied to the specimen by selecting the optimal consolidation
parameter among t50, t90 and t100, improving efficiency and cost
effectiveness.

Note:
1. shear box, hollow punch, tamper (see accessories) and Software
S277-41N are not included and have to be ordered separately
2. The pneumatic shear machine mod. S276-02 requires an air
compressed source.
3. The machine is configured to accommodate an additional piston
to apply a max vertical load of 10000 N

RECOMMENDED ACCESSORIES
S262-11 AIR FILTER, auto-draining, it reduces up to one micron,
complete with discharge
S277-41N SOFTWARE SHEAR LAB CONNECT
For fully automatic data control, acquisition, processing and
visualization in direct/residual shear tests, with graphics on all the
test phases (technical details: see p. 542)
