4.1.4.3 Flow Sensor Over Pressure Limits
The flow sensor in the Sprint iQ can be damaged by too much
pressure. The Sprint iQ automatically monitors the pressure and
will stop a flow test if the pressure is too high. The below table
shows the maximum pressure associated with each flow range.
Flow Range Over Pressure Limit
10 sccm 15 psig Max
50 sccm 15 psig Max
200 sccm 15 psig Max
1,000 sccm 15 psig Max
5,000 sccm 60 psig Max
20,000 sccm 60 psig Max
4.1.5 Burst Test
In burst testing, Sprint iQ looks for devices to open at some point
during pressurization and rapidly drop toward zero pressure.
Achieving the burst is the desired outcome of the test. When the
burst occurs in the correct pressure range and time period,
Sprint iQ gives a pass indication. Test engineers often use a burst
test to check pressure relief mechanisms designed to open within
a preset pressure range. Burst tests are also used to check the
friction relief-point of hydraulic and pneumatic devices.
Flow Control
Use Sprint iQ’s built-in flow control on the back of the tester to
set the pressure increase, also called ramp rate. Trial and error is
used to adjust the flow control to get the best rate of pressure
increase.
