Submersible load cells

Main features
  • High accuracy
  • No ram friction effect on measurement
  • Low hysteresis
General description
General description
Submersible (internal) load cells have been designed to work inside the triaxial cells. They have a lower hysteresis and very good linearity together with a substantial over load safety feature. They are supplied complete with rams to suit \#banded-triaxial-cells-and-accessories\# and Triaxial cells for advanced applications(Tri-Cell Plus models). The 15.5 mm dia. ram fits the 28-WF4050 cell, whilst the 25 mm dia. ram fits all the other cell models. Standard models of submersible cells are also supplied complete with extension kit for small samples.
The versions for Dynamic testing are practically identical to the standard models except for the connections to the system.
