High-Speed Helium Leak Testing for the Pressure Sensor Industry
When pressure sensors operate under extreme hydraulic or industrial conditions, even a microscopic fissure in a laser weld or diaphragm causes signal drift or complete field failure. For manufacturers, verifying absolute hermetic sealing without bottlenecking the assembly line is a constant challenge.
Engineered specifically for automotive, hydraulic, and industrial sensor production, our bell-type vacuum chamber helium leak detection system delivers high-speed, high-pressure quality control.
Designed to handle high helium test pressures from 1.5 to 7.0 MPa, the system achieves a rapid cycle time of just 7 to 15 seconds per piece. Its automated 3-level detection process instantly screens for gross, medium, and fine leaks down to 1.0E-6~1.0E-5Pa.m3/s, ensuring 100% quality assurance at true mass-production speeds.
Key Advantages for Sensor Manufacturers:
-
Safety & Ergonomics: Bell-type structure equipped with safety light curtains and electrical interlocks for high-pressure protection.
-
Closed-Loop Savings: Automated helium recovery system reclaims test gas to minimize daily operating expenses.
-
Smart Factory Integration: Full MES and database connectivity automatically logs test data for complete batch traceability.
