Pressure transucers for triaxial test

Main features
  • Used for the measurement of cell pressure, back pressure, pore pressure (water or air).
  • Outstanding performance and stability 
  • Good accurancy 
  • Ranges from 0  to 1000, 2000, 3500 kPa depending on the model
General description
General description

Pressure transducers are used for the measurement of cell pressure, back pressure, pore pressure (water or air).They have to be connected to triaxial cells by the suitable De-airing block. See accessories.
The transducers are base on the extensimetric measurement principle with strain gauges on the metal base. 
Two series are available according to the compatibility with the machine, please refer to the technical specification and transducers compatibility table below.
