Overview
The SUNS SKT3000 Shell Hydrostatic Pressure Integrity Tester is an industrial-grade, programmable pressure resistance verification system engineered for quantitative assessment of structural integrity and leak-tightness in hollow shell-type components under controlled hydrostatic stress. It operates on the principle of regulated pneumatic pressurization—applying calibrated, sustained, or ramped-over-time gas pressure to enclosed cavities while continuously monitoring pressure decay, dwell stability, or catastrophic failure thresholds. Designed specifically for quality assurance in manufacturing environments where regulatory compliance and repeatable pass/fail criteria are critical—including automotive fluid reservoirs, medical device housings, consumer electronics enclosures, and HVAC component casings—the SKT3000 delivers traceable, audit-ready test records aligned with ISO 5208 (industrial valve leakage classification), ASTM F2096 (bubble leak testing correlation), and internal OEM validation protocols.
Key Features
- Configurable pressure range from 30 to 3000 kPa, with fine resolution of 0.1 kPa and full-scale accuracy of ±0.2 %FS—enabling precise discrimination between marginal and compliant units.
- Dual pressure control options: mechanical regulator for manual setup simplicity or electric servo-controlled regulation for automated ramp-and-hold sequences with <±1 %FS regulation fidelity.
- Integrated safety architecture featuring dual-redundant light curtain sensing and a certified explosion-resistant hinged door, meeting EN ISO 13857 and ANSI B11.19 requirements for operator protection during high-pressure testing.
- 10-inch capacitive touchscreen HMI with intuitive workflow navigation, real-time pressure/time curve visualization, and on-screen pass/fail status flagging based on user-defined acceptance criteria.
- Industrial I/O capability (6 inputs / 6 outputs) supports external PLC integration, fixture actuation, and multi-station synchronization—ideal for inline QA stations or automated production cells.
- Comprehensive data handling via USB export (CSV format), optional RS232/RS485 serial communication, and standard RJ45 Ethernet port for networked lab management systems or MES integration.
Sample Compatibility & Compliance
The SKT3000 accommodates a broad dimensional envelope—up to 230 mm in length, 80 mm in width, and 230 mm in height—making it suitable for cylindrical, rectangular, and irregularly shaped shells including battery enclosures, sensor housings, syringe barrels, and pneumatic actuator bodies. Its modular sealing interface allows rapid tooling adaptation using custom O-ring fixtures or vacuum-assisted clamping mechanisms. All test procedures support GLP/GMP-aligned documentation practices: timestamped event logs, operator ID tagging, and electronic signature fields are embedded within the firmware. The system complies with CE marking directives (2006/42/EC Machinery Directive, 2014/30/EU EMC Directive) and is designed to facilitate FDA 21 CFR Part 11 readiness when deployed with validated software configurations.
Software & Data Management
Firmware includes embedded test sequencing logic supporting up to 99 programmable test profiles, each defining pressure setpoint, ramp rate, hold duration (0.1–999.9 s), burst termination threshold, and pass/fail tolerances. All test data—including raw pressure vs. time traces, event timestamps, environmental conditions, and operator annotations—are stored locally and exportable via USB. Optional PC-based analysis software (SUNS TestSuite Pro) enables statistical process control (SPC) charting, CPK calculation, comparative trend analysis across shifts or batches, and PDF report generation with embedded digital signatures. Audit trails record all parameter modifications, user logins, and calibration events—fully traceable per ISO/IEC 17025 Clause 7.7 requirements.
Applications
- Validation of hermetic seals in implantable medical devices prior to sterilization cycle qualification.
- Production-line burst testing of ABS/PC plastic fuel caps and coolant expansion tanks per SAE J1797.
- Reliability screening of aluminum die-cast EV battery module housings against IP67/IP6K9K ingress specifications.
- Supplier qualification testing for aerospace hydraulic manifolds under MIL-STD-810H Method 510.6 (pressure altitude simulation).
- Process capability studies for ultrasonic welding parameters in consumer appliance enclosures using pressure decay rate as a surrogate quality indicator.
FAQ
What pressure media does the SKT3000 use, and are alternative gases supported?
The system is configured for compressed, oil-free, desiccated air (0.4–0.8 MPa supply). Nitrogen may be used as an alternative inert medium upon customer request; however, compatibility must be verified with SUNS engineering to ensure regulator and seal material suitability.
Can the SKT3000 perform differential pressure decay testing?
No—the SKT3000 is a single-chamber hydrostatic tester. It measures absolute pressure retention or burst failure; it does not incorporate reference chamber instrumentation required for differential decay methods per ISO 15497.
Is calibration certification included with delivery?
Yes—a factory-issued NIST-traceable calibration certificate covering pressure transducer and timer modules is provided. On-site recalibration services and accredited third-party calibration support are available through SUNS global service partners.
How is firmware updated, and is version history maintained?
Updates are delivered via USB stick and installed through the HMI. The system maintains a complete firmware revision log, including installation date, version number, and checksum verification—accessible in the Maintenance menu.
Does the SKT3000 support remote monitoring or cloud connectivity?
Native cloud upload is not embedded; however, the RJ45 Ethernet interface enables integration with local SCADA platforms or custom MQTT/HTTP API gateways via external edge computing hardware. SUNS provides documented Modbus TCP register maps for seamless interoperability.
