The Electronic Programmable Regulator can also be used
instead of the Fast Fill option.
A program
preceding the
actual test
program is
created which
contains no
active test
limits but is set
to a target
pressure higher than the actual leak test pressure. This higher
pressure fills the test part faster (equivalent to a Fast Fill).
After this step is completed, the first program links to the
actual test program with the target test pressure.
Ramp Rate
Ramping is used in burst, crack and creep testing. Ramp Rate
is an increase in pressure over time. Sprint iQ’s Electronic
Programmable Regulator precisely controls the ramping
pressure.
Often, cycle time can be saved and burst or crack event
sensitivity increased by quickly jumping to a minimum
starting pressure (without ramping) below the typical pressure
where a burst or crack event is expected. A ramp can then be
started until the event occurs. The Electronic Programmable
Regulator option is ideal for this purpose (not possible with a
standard Burst or Crack equipped tester where pressure must
start at or near zero pressure).
To program a ramp, the user first enters a starting pressure and
then a rate in pressure units per second. For example, if 45
psig ramp starting pressure and 10 psig/s ramp rate is entered,
at the start of the test cycle, pressure will immediately go to
