The LTI-5000 is a PC based unit that can be used for performing mass flow or pressure decay tests. This unit is recommended for applications that require the system to be placed on a plant network. This unit had the most flexible data collection means. The standard data collected is test start and completion time, test channel and limit table used, end-of-test pressure and flow reading, test result, and data export verification.
The LTI-5000 displays corrected airflow readings through the use of a mass flow transducer. This state-of-the-art technology provides test results, which are independent of daily changes in barometric pressure and ambient temperature. This leak test instrument measures the leakage or flow of air through the part under test at a specific test pressure. When the leak test is initiated this instrument automatically pressurizes the part, allows the air pressure within the part to stabilize, and measures the actual leakage through the part. The leakage or flow is displayed in actual engineering units.
Two pressure decay/change methods are available depending upon the specific application. Applications with a high leak rate specification or a small test volume utilize a gage-pressure-decay test method. Applications with a low leak rate specification or a large test volume will use a pressure-differential-decay test method. With either method this leak test instrument pressurizes the test part, allows the air pressure within the part to stabilize, and measures the decay/change in pressure.
