Overview
The INFICON LDS3000 is a high-performance, compact helium and hydrogen mass spectrometer-based leak detector engineered for integration into automated industrial leak testing systems. Operating on the principle of residual gas analysis via quadrupole mass spectrometry, the LDS3000 selectively detects helium (4 amu) and hydrogen (2 amu) tracer gases with exceptional sensitivity and speed—enabling quantitative leak rate measurement down to 1 × 10⁻¹¹ mbar·L/s. Its design philosophy centers on system-level engineering efficiency: reduced footprint (330 × 240 × 280 mm), low mass (≤12 kg), and minimized cabling complexity eliminate the need for traditional 19-inch rack-mounted controllers. This architecture supports seamless OEM integration in automotive component testing, vacuum chamber validation, HVAC coil inspection, semiconductor tool qualification, and medical device packaging integrity verification—applications where spatial constraints, cycle time reduction, and long-term operational stability are critical.
Key Features
- Ultra-compact form factor (330 × 240 × 280 mm) and lightweight construction (<12 kg) optimized for embedded integration in production-line leak test stations.
- Sub-second detection response for leaks as small as 1 × 10⁻¹¹ mbar·L/s using helium or hydrogen tracer gas—validated per ISO 20485 and ASTM E493 calibration protocols.
- I-CAL intelligent auto-calibration: full sensor calibration completed in ≤20 seconds; field recalibration required only after major maintenance or extended idle periods.
- Modular interface architecture supporting analog outputs (0–10 V, 4–20 mA), RS232, RS485, USB 2.0, and optional PROFIBUS-DP for PLC synchronization and Industry 4.0 data exchange.
- Optional resistive touchscreen HMI (7-inch, IP65-rated) enables local operator interaction without external PC dependency—ideal for standalone benchtop or mobile test cell deployment.
- Backward compatibility with LDS2010 configuration files, alarm thresholds, and scan routines—reducing migration effort during system upgrades.
Sample Compatibility & Compliance
The LDS3000 is designed for use with helium (He-4) and hydrogen (H₂) as safe, non-toxic, and cost-effective tracer gases—particularly advantageous in environments where helium conservation or regulatory restrictions apply. It complies with electromagnetic compatibility standards EN 61326-1 (industrial environment) and safety standard EN 61010-1. Its vacuum interface accommodates standard KF-25/40 and ISO-KF flanges; inlet pressure range: 1 × 10⁻⁴ to 1 × 10⁻¹ mbar. The instrument meets requirements for GLP-compliant documentation when paired with INFICON’s certified software packages, supporting audit trails, electronic signatures, and 21 CFR Part 11–compliant data archiving via optional firmware modules.
Software & Data Management
The LDS3000 operates natively with INFICON’s LeakTest Suite v4.x, a Windows-based configuration and diagnostics platform supporting real-time leak rate trending, multi-channel synchronization, and statistical process control (SPC) charting. All communication interfaces support ASCII command protocol for custom SCADA or MES integration. Data logging includes timestamped leak rate values, sensor status flags, calibration history, and alarm event logs—all exportable in CSV or XML format. Optional firmware upgrades enable OPC UA server functionality for secure, platform-agnostic data publishing across enterprise networks.
Applications
- Automotive: Fuel rail, brake line, EV battery coolant loop, and airbag inflator assembly testing.
- Electronics: Hermetic sealing validation of MEMS sensors, RF filters, and optoelectronic housings.
- Medical Devices: Integrity verification of IV bags, implantable device enclosures, and sterilization pouches per ISO 11607.
- Vacuum Equipment: Commissioning and preventive maintenance of diffusion pumps, sputtering chambers, and electron beam welders.
- Aerospace: Critical joint and manifold leak screening in hydraulic and environmental control systems.
FAQ
What tracer gases does the LDS3000 support?
Helium (4 amu) and hydrogen (2 amu) — both detectable simultaneously with independent threshold settings.
Is the LDS3000 suitable for continuous 24/7 operation in production environments?
Yes. Its solid-state ion source, sealed detector housing, and thermal management system are rated for unattended operation at ambient temperatures from 10–40 °C and relative humidity up to 80% non-condensing.
Does it require routine filament replacement?
No. The LDS3000 employs a cold-cathode ion source with no consumable filaments, eliminating scheduled replacement and reducing total cost of ownership.
Can it be integrated into a PLC-controlled test cell without a host PC?
Yes. Using digital I/O signals and serial/fieldbus protocols, all critical functions—including start/stop, pass/fail output, and alarm reset—can be managed directly by programmable logic controllers.
How often must the LDS3000 be calibrated?
Under normal operating conditions, calibration is recommended annually or after exposure to gross contamination; I-CAL ensures traceable accuracy within ±5% of reading across its dynamic range.
