Leakage testing device LTS compact Basic Functions The leakage testing device LTS compact can be used for testing leakage on hollow bodies of all kinds, applying either compressed air or vacuum. Assuming the form of a desktop unit it is operated either manually or optionally via external control signals . Designed on one specific test method, it incorporates the following features: - Test-result indication of „good“ and „reject“ results catered for by clearly visible indicator lamps, - Measurement-value indication during four time-based test steps, - numerical indication of the test steps, - Constant self-testing through monitoring of measurement recording signals, - Serial Interface for outputting test results on an inline printer or PC, - Test-run sequence controllable either manually or via external signals (option), - Diagnostic functions, - One test program with adjustable limits and step times. Available Optional Features Digital inputs and outputs to a master control Strengthened power supply, Programming pin for protection of the stored data against unauthorized parameter changing ( not available for Flow Method), Test and calibration tools. Technical Data Energy Supply: electrical: U = 110 - 240 V, 47 - 60 Hz pneumatic: clean compressed air, min 1 bar above test pressure, max. 7 bar or vacuum Test Pressure and Range of Measurement: corresponding to installed pneumatic module Resolution of Measurement: 1 / 20 000 of sensor range of measurement Adjustable Times: filling time 0,05 ... 999,95 sec Designs: Desktop housing IP 40 - y2 19“, 3U high 235mm x 140mm x 326mm (W x H x D) Energy supply ports, serial interface, I/O interface and power switch at the backside. Test Method The leakage testing device LTS compact operates (corresponding to the installed pneumatic module) according to the relative-pressure method, Relative-pressure Method Available test-pressure and measuring ranges: -1 ... 0 bar Other ranges of measurement available on request The adjustment of the test-pressure is done manually at a high precision pressure regulator.

Leakage testing device LTS compact Testing Test Procedure - Start the test by pressing the „Start“ button on the front panel or by cutting in an external control signal (option). - Filling function - Stabilization - Testing - Hold (Measurement display is frozen) - Evaluation „Reject part“ test results must be acknowledged by pressing the "Stop" button or by actuating the external control signal (option). If the result is „good“, the sequence will continue, the next step being - Emptying It is possible to stop the test run at any stage by pressing the „Stop“ button. In this state the step display...
