Overview
The SUNS SC10005 Differential Pressure Leak Tester is an industrial-grade, microprocessor-controlled instrumentation system engineered for high-reproducibility leak detection and quantitative leakage rate measurement in sealed components. It operates on the differential pressure decay principle: a test part is pressurized to a defined setpoint within a calibrated range, isolated from the supply source, and monitored for pressure loss over a user-defined stabilization and test period. The instrument compares the pressure decay in the test chamber against a stable reference chamber—both subjected to identical thermal and environmental conditions—to eliminate drift artifacts caused by temperature fluctuation or barometric changes. This dual-chamber architecture, combined with auto-compensating environmental drift correction algorithms, ensures metrological robustness across production-floor environments where ambient stability cannot be guaranteed. Designed for integration into automated assembly lines and QC laboratories, the SC10005 meets foundational requirements for ISO 9001-compliant process validation and supports audit-ready documentation workflows.
Key Features
- Real-time differential pressure monitoring using imported SMC precision pressure regulators and high-stability OEM piezoresistive sensor chips with integrated temperature compensation
- Dedicated 32-bit embedded processor paired with 24-bit analog-to-digital conversion for sub-millisecond signal acquisition and AI-accelerated response during transient decay analysis
- Self-developed real-time OS with intuitive 10-inch capacitive touchscreen interface—optimized for glove-compatible operation and rapid parameter setup without menu nesting
- Auto-drift compensation algorithm continuously corrects for thermal expansion effects and atmospheric pressure drift during extended test cycles
- Expandable hardware architecture supporting up to 8 parallel test channels via modular I/O expansion (requires optional channel controller module)
- Integrated industrial IoT stack compliant with MQTT v3.1.1 and HTTP RESTful APIs—enables secure remote configuration, firmware updates, and live telemetry streaming to MES/SCADA platforms
- Native barcode scanner support (USB HID mode) for automatic work order binding, part serialization, and unambiguous test record linkage
Sample Compatibility & Compliance
The SC10005 accommodates a broad spectrum of sealed assemblies including automotive fuel systems, medical device packaging (ISO 11607-1), EV battery modules, consumer electronics enclosures, pneumatic actuators, and HVAC components. Its configurable test ranges—from low-sensitivity 5–50 kPa applications (e.g., pharmaceutical blister packs) to high-pressure 10–1500 kPa validation (e.g., hydraulic manifold blocks)—allow method transfer across diverse product families without recalibration. All pressure transducers are traceably calibrated to NIST-traceable standards, and the system supports GLP/GMP-aligned data integrity protocols: electronic signatures, audit trails for all parameter modifications, and immutable timestamped records stored locally and exportable via USB or network share. The device conforms to IEC 61000-4 electromagnetic compatibility standards and carries CE marking for use within the European Economic Area.
Software & Data Management
Built-in firmware provides full local data logging—including raw pressure vs. time curves, calculated leak rates, pass/fail status, operator ID, and environmental metadata—with retention for ≥100,000 test records. Data export is supported in CSV and XML formats via USB mass storage mode; network-enabled units allow scheduled FTP/SFTP uploads or direct database insertion using ODBC-compliant drivers. Optional PC-based LabManager™ software (v4.2+) adds statistical process control (SPC) charting, Cp/Cpk trending, failure mode clustering, and automated report generation compliant with FDA 21 CFR Part 11 requirements—including role-based access control, biometric or PKI-based electronic signatures, and tamper-evident audit logs. All communications over Ethernet utilize TLS 1.2 encryption, and firmware updates require signed digital certificates to prevent unauthorized modification.
Applications
- Automotive: Fuel rail assemblies, brake calipers, turbocharger housings, and ADAS sensor enclosures requiring IP67/IP69K validation

- Electronics: Hermeticity verification of MEMS packages, waterproof smartphones, and wearable sensors
- Energy: Leak quantification in lithium-ion battery module cooling plates and hydrogen fuel cell stack manifolds
- Industrial Automation: Functional testing of solenoid valves, pneumatic cylinders, and vacuum gripper systems prior to shipment
FAQ
What pressure sources are compatible with the SC10005?
The instrument requires a clean, oil-free, desiccated compressed air supply at 0.4–0.8 MPa. An inline coalescing filter (≤0.01 µm) and refrigerated dryer are strongly recommended to prevent sensor contamination.
Can test methods be password-protected and version-controlled?
Yes—each method file includes revision stamping, creation/modification timestamps, and encrypted storage. Administrator-level credentials are required to overwrite or delete active methods.
Is calibration certificate included with shipment?
A factory calibration report traceable to national standards is provided with each unit. On-site accredited calibration services (ISO/IEC 17025) are available upon request.
How does the system handle temperature-induced drift during long-duration tests?
The dual-chamber differential architecture inherently cancels common-mode thermal effects. Additionally, real-time ambient temperature sensing feeds a dynamic offset correction model that adjusts baseline referencing every 200 ms.
Does the SC10005 support statistical process control (SPC) out-of-the-box?
Basic SPC metrics (X-bar, R-chart limits) are computed onboard and displayed in real time. Full SPC functionality—including capability analysis and alarm thresholds—is enabled via LabManager™ software.
