The Crack Event
For a crack test, Sprint iQ is equipped with two sensors. The
standard transducer measures the pressure rise being feed to the
test part, on the upstream side. The second sensor is the
downstream sensor. The crack event is a change in pressure or
flow on the downstream side of the test part. This downstream
sensor can be either a pressure or flow sensor.
Two measured values are associated with an event value:
• The peak pressure attained. (Upstream side)
• The amount of pressure or flow rise. (Downstream side)
Both sensors are monitored at the same time. To register as a pass,
the upstream peak pressure must be within the min and max crack
window AND the downstream pressure or flow must exceed the
event setting. For example, if the event is set at 0.05 psig, the
down stream pressure is monitored till it increases more than 0.05
psig. At that time: the peak upstream pressure must fall within the
minimum and maximum crack settings for the test to pass.
Programming a Crack Test
The parameters of a crack test are set in the same manner as a
burst test.
