LTI-5000 |
|
 Single Channel LTI-5000 Leak Test |
||
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. |
|||
| TEST METHODS | |||
| MASS FLOW | |||
|
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.
|
|||
| PRESSURE DECAY/CHANGE | |||
| 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. | |||
| SETUP & OPERATION | |||
The LTI-5000 is easy to setup and operate with the menu driven touch-screen in response to inputs from the operator.
There are 1200 limit tables available for each channel. Setup parameters for each table include fast fill pressure and
tolerance, test pressure and tolerance, test times, accept/reject limits, and consecutive reject limits. Tester setups include
communications port parameters, data input and output devices configuration, and security options. The LTI-5000 can be user programmed to run customized test sequences and control all tester input/output functions. Transducer calibration is also menu driven. Optional pendant boxes are available with local accept/reject pilot lights and a start/stop push button. |

SYSTEM ENCLOSURE |
One (1) NEMA 12 electrical enclosure and up to sixteen (16) pneumatic enclosures can be provided. The electrical
enclosure contains the Pentium based PC with a color touch-screen display, power supplies, and indicators.
Communication ports on the side of the enclosure allow the controller to output results to a data collection device or
printer. Test results may also be output to a floppy drive or to the Ethernet port. The pneumatic enclosure(s) contain
the pressure and leak transducers, regulators, and valves. Ports are provided for air and power connections. The standard color for the TI-5000 is white. |
