Pressure Control
Specimen pressure is controlled by means of a Eurotherm controller and an
ER-3000 pressure regulator. The Eurotherm is a digital, programmable controller
and the ER-3000 is a very precise programmable pressure regulator. Operators
enter test parameters (maximum pressure and ramp rate) into the Eurotherm,
which then sends output signals to the ER-3000 based on these test parameters.
The ER-3000 controls a dome regulator to pressurize the specimen. The
Eurotherm displays the current specimen pressure and the programmed setpoint.
It also records the maximum pressure reached (burst pressure) by the specimen.
For more information on the Eurotherm controller, refer to page 22 and to the
manufacturer’s information included separately in this manual. For more
information on the ER-3000, refer to the manufacturer’s information included
separately in this manual.
High Volume Flow Regulator
Stage II and Stage III burst systems are equipped with a high volume flow
regulator that controls the flow to the specimen. Operation of the high volume
flow regulator is controlled via the ER-3000/Eurotherm controller.
Accumulator
An accumulator provides the volume capacity necessary for testing. The
accumulator(s) can vary from 1 gallon to two 10-gallon units or larger depending
upon the volume needed for the individual testing requirements. Refer to the
manufacturer’s instructions for more specific information about the accumulator.
Pressure Transducers
The burst system is equipped with two pressure transducers. One transducer
communicates with the ER-3000 for specimen control; the other is located on the
return line from the specimen and communicates with the Eurotherm controller
for its display and programmed alarms. For more information on the programmed
alarms, see page 25.
Water Filter
Protects the system from dirt particles to help keep system maintenance to a
minimum.
