MTS Model 286-31 Transient Permeability Pore Pressure Intensifier - Manual (Page 8)

286.31 Transient Permeability Pore Pressure Intensifier 8
Control Panel Valves
Introduction
1 Intensifier Fill controls the flow of fluid from the Reservoir into the Pressure
Intensifier.
2 Reservoir Fill/Drain controls the flow of fluid into the Fluid Reservoir when the 286.31 is
connected to a fluid supply.
3 Reservoir Return is normally kept closed.
4 Permeability Fluid Input 1
Permeability Fluid Input 2 control the filling and pressurization of Reference Volumes 1 and 2.
5 Transducer Input 1 Transducer
Input 2 apply Reference Volume 1 and 2 pressures to the Pressure Transducer
when open.
6 Transducer Pressure Balance protect the pressure transducer from damaging high pressures. It is
normally left open. When closed it exposes this transducer to the
pressure differential between Reference Volumes 1 and 2.
7 Permeability Input Permeability
Output apply Reference Volume 1 and 2 pressures to the specimen in the
triaxial cell when open.
8 Pore Fluid Input Pore Fluid
Output bypass the permeability fluid circuit when open.
