The leakage test system for industrial leakage and flow tests Know-how from more than 50 years of experience combined with up-to-date inspection technology

Basic functions The intelligent leakage test system INTEGRA can be used for leakage testing, flow testing or functional testing with overpressure or vacuum. Assuming the form of a desktop unit, it is operated either manually, via external control signals or via an operation program of a connected PC. The following scope of functions is the same for all various types. ■ 255 test programs can be stored Several parallel running test processes possible ■ Up to 3 test circuits can run in parallel and asynchronously ■ Communication with PLC and control of devices and machines via field bus system,...

Functional diagram Relative-pressure method Test methods Differential-pressure method Relative-pressure method Flow method In conducting the leakage test according to the differential-pressure method, the test P specimen and a tight reference volume are E filled with equal pressure. Afterwards they are both sealed off separately. After a stabiPrüfling lisation time has elapsed, during which temperature equalization takes place between the test specimen, testing equipment and test medium, the actual process of testing Functional diagram commences. If theFlow method (volume will result in test...

Special devices The leakage test system INTEGRA is a multifunctional test device that can be used to configure customer-specific special applications. This image shows an example. This is a flow test device for especially large test volumes such as exhaust systems or ventilation pipes. The entire test pneumatic system is housed in a separate casing. Thus it is possible to insert application-specific components without having to forego the familiar functionality of INTEGRA. Because of the intelligent, freely configurable operation software, a wide range of various tests and test processes can...

Freely programmable device control All leakage test systems in the INTEGRA series -even on the basic version - are provided with digital in- and outputs capable of being used for device control. Controlling extensive test stands combined with complex processes is reachable with optional available bus coupling modules (Profibus, Interbus,...) and with the freely programmability of additional operations. Thereby several operations are running capable parallel to the test process. Automatic test process optimization autoTune In order to test components for leakage, it is usually necessary (in addition...

Communication environment e.g. via Internet remote maintenance Supervisory level Control level Field bus (e.g. PROFIBUS, Interbus) simple test stand complex test stand Process level The leakage test system INTEGRA can be integrated completely into modern communication environments and is ready for the future. Data exchange and control functions can be realized via e.g. Ethernet on the supervisory level, via PROFIBUS or Interbus on the automation level, via serial interface or via 16 digital I/Os. It is optimally prepared for future applications due to the use of interchangeable coupling modules....

Graphical display The installed LCD graphic display serves to indicate the time curve of the measured values, the individual sequence steps of the test being separated by vertical lines as a mean of improving overall clarity. The zoom function facilitates freely adjustable setting of the display range, thus enabling partial test areas of interest to the viewer to be analysed applying increased resolution. The display of the relative-pressure and the differential-pressure could be changed. This caters for good functional clarity, even when measuring fine pressure changes under high test pressure....
