Eight sealing cap screws attach the bell to the platen assembly to make a sealed pressure chamber for
the specimen.
Confining fluid enters the chamber through the lower confining fluid port. It drains through this port when
compressed air enters the upper confining fluid port. The pressure relief valve opens when pressures rise
above a preset limit.
Pore pressure enters through the pore pressure ports during pore pressure tests. The upper and lower
vents stay open in compression tests to alert you to O-ring failure. The special use ports are for custom
uses.
The internally mounted force transducer directly reads the true deviatoric load on the specimen. Two force
ratings are available.
Optional internal heating rods heat the chamber. The platen assembly has fluid ports and electrical
feedthroughs.
