Pressure Testing Units
When it comes to integration of a pressure test unit into your assembly verification application, turn to Cincinnati Test Systems (CTS). With over thirty years of experience in design and build, along with our integration of pressure test applications using methods like hydrostatic testing to proof testing, and ranging from 5 inches of water to 30,000 PSI, you can rest assured your test performance is optimized with the utmost safety in mind.
Hydraulic and Hydrostatic Testing
CTS can design, build, and integrate low and high pressure hydrostatic testing applications used for burst, leak, flow, calibration, or integrity test of customer’s parts while collecting detailed data for test evaluation.
A common technique used in detection of blockage within the part under test. The test uses constant applied pressure from a fixed source to detect open or partially closed (blocked) states by measuring and recording backpressure at the inlet (upstream) of the part at the end of a fixed time period.
Pressure Rise/Increase Testing
Pressure test units used for multiple purposes including detection of leakage from a part or to detect restrictions/blockage within the part under test. The test, in most cases, operates by measuring any rise in pressure on the lower pressure side of a barrier or wall designed to be sealed off from a higher pressure side (sometimes a chamber around a filled or sealed tested part).
A technique used to stress the part under test to ensure it was capable of maintaining a certain level of pressure or vacuum and hold that for a period of time without gross failure. The test operates by ramping pressure or vacuum to the test part at a fixed rate for a fixed period and then holding that final pressure for an additional fixed time period. Any drop below a minimum pressure level indicates the part has failed.
Ramp to ∆P Event Testing
Often used to test check valves, pressure relief valves or other products designed to drastically change state (vent or seal) when pressure is increased or decreased. This pressure test is also often used for burst testing. The test operates by ramping pressure to the test unit part up or down at a fixed rate until a sudden change of pressure is seen on the inlet of the part (detecting the change in state or “event”). Any event detected above or below the expected range of final event inlet pressures is failed.
Pressure Decay/Vacuum Decay Testing
This is the single most common pressure test unit used in leak testing today. The test fills or charges the part to a target pressure, isolates that pressure, and measures the decay of pressure over a fixed time period. The final result can be displayed in: Leak Rate, ∆P or ∆P/∆T.
CTS has had extensive experience in pressure testing Automotive, Medical, Consumer Goods, Energy, Military, Transportation, and other industry applications for more than 30 years. We will work with you to determine the best method to use, whether it is one of our pressure testing units or other some other method to achieve your testing goals.
