Triaxial cells for advanced applications

BS 1377:7 | ASTM D2850 | ASTM D4767 | BS 1377:8 | NF P94 070 | NF P94 074 | ASTM D7181
PRINCIPALES CARACTERÍSTICAS
  • Light alloy construction, stainless steel ram and O ring seal
  • Built-in cell ram clamp
  • Includes pillar and anvil for strain dial gauge or transducer
  • Five on/off no-volume changes valves fit as standard
  • For sample sizes between 38 and 150 mm dia.
  • Standard length chambers accepts submersible load cells
  • Rapid assembly design
  • Cells are designed to accommodate a specimen with a high twice its diameter
  • Base adapters, plinths, top caps, porous disc, rubber membranes and sealing rings are not included. See accessories.
  • Models :28-WF4070; 28-WF4100; 28-WF4150 with  pedestal and top cap can be used also to perform stress path tests and dynamic test using a vaccum attachment 
  • Models :28-WF4070; 28-WF4100; 28-WF4150 can be upgraded with an advanced kit making them compatible with mini on sample transducers and bender elements.
DESCRIPCIÓN GENERAL
DESCRIPCIÓN GENERAL
The cell essentially consists of a trasparent banded chamber to prevent excessive expansion during the test and to protect against explosive failure when used with compressed air systems. 
The design of the cell ensure vertical alignement of the cell ram by clamping the Perspex wall separately from the cell top.

Pedestal
Adopting the new range of pedestals it is possible to test specimens with different diameters into the same triaxial cell.
The  codes are self-explanatory:
28 – WF4xxx/YY
xxx = refers to specimen dia.
031 = 38mm
051 = 50mm
071 = 70mm
101 = 100mm
151 = 150mm
 
YY = refers to triaxial cell
5 = 50mm
7 = 70mm
10 = 100mm
15 = 150mm
