The INTEGRA flow measurement product family offers devices for automated air leak testing and flow measurement in manufacturing environments. The amount of air flowing out through the leak or a defined opening is measured using a laminar flow element or the mass flow method. In comparison with an upper limit value, the tightness of a component or the correct flow rate can be checked in comparison with upper and lower limit values. Flow rates of 100 ml / min, which corresponds to a limit leak rate of 1.6 mbar l / s, up to 125 l / min can be measured. The devices are suitable for tests in the pressure range from -1 to +1 bar with typical component volumes from 0.02 to 100 l. With the autoTune function in the INTEGRA version, the device independently determines the optimal process parameters based on a sample. For this purpose, the user has to enter characteristic values ​​known from the drawing. With the autoTune function, machine runtimes that are too long due to runtime specifications set too long or pseudo rejects due to runtimes set too short can be reliably avoided by inexperienced users. With the LTS 670L device variant, predetermined test sequences can be configured by setting the limit values. The INTEGRA version offers the possibility to create extensive test programs including the device control by means of a graphic color display. Up to three test or control programs, including different test methods, can run asynchronously during operation. Serial and digital interfaces and modules for all bus systems as well as for Ethernet and Firewire are available for the transfer of measurement data. The quickShuttle plug-in single-button remote control, together with the built-in keyboard, allows convenient input directly on the device. The INTEGRA devices can also be operated and operated remotely.
