The device has a dimension of 1mm x .8mm x 0.5mm with cavity about 0.1 mm^3. My questions are: 1. Is it possible to use He test to check the leakage rate and how to do it? 2. Are there any companies to provide this kind of service? Your suggestion is higly appreciated! Duke    Reply  Translate  Close

The sensor system is designed for permanent monitoring or periodic inspection tasks. Sensors are available for different AE-frequency ranges optimized for corrosion and fatigue crack detection and other applications. The ISAFE 3 sensor system consists of an AE-sensor (model ISAS3) certified according to ATEX/IEC for installation in zone 0, gas group IIC, IP68, 20 to +60 °C, and a signal isolator (model SISO3) certified for installation in zone 2. An ISAS3 sensor can be mounted in atmosphere or submerged, e.g. in water or crude oil. It is supported by mounting tools for temporary (magnets) or permanent (welded) installation. ISAFE3 supports automatic sensor coupling test and can be used with any AE signal processor supporting 28V supply at 90 mA peak, e.g. Vallen Systeme ASIP-2/A. > 2 Showcases Navic - Steerable Modular Automated Scanner StandJIREH Industries The Navic is a modular, motorized, steerable scanner designed to carry multiple attachments used ... in various scanning and inspection applications.
