OverviewT3LPQ is an electro-pneumatic instrument for leak testing that measures leak flow rate directly with a mass flow sensor. It is designed for fast, repeatable measurements and integration in test benches, production lines or fully automated systems.
PerformanceThe balanced-pressure method provides measurements independent of the tested volume, improving stability and precision. Electronic pressure regulation and a colour touchscreen with real-time graphical and numeric test views simplify programming and monitoring.
ConnectivityThe instrument provides modern interfaces for industrial integration:
- Digital I/O for PLC connection
- USB host for storage and PC connection
- Two serial ports (RS232 / RS485)
- Ethernet (LAN) with Profinet support for network storage/communication
Benefits- Leak measurement with mass flow sensor: range ≥2 cm3/min to 100 cm3/min; resolution up to 0.01 cm3/min
- Electronic regulation of test pressure from 5 mbar to 1 bar (up to 2 bar depending on conditions)
- Balanced-pressure method for tests independent of product volume (suitable for volumes ≥10 cm3 to 2 L)
- 7" full-colour LCD touchscreen with graphic real-time test view
- Comprehensive interfaces: Digital I/O, USB, RS232/RS485, Ethernet
- Test data storage on USB pen drive or via LAN/Ethernet/Profinet
- Control of external devices: printer, barcode/QR-code reader, remote keypad, external valve for volume check, air filters
- Dedicated Software Manager for data collection, parameter programming and SPC analysis
