Description
The GDUI-411PD Pro is a cost-effective, field-optimized entry-level dual-function acoustic imaging instrumentexclusively designed for non-contact, real-time detection and localization of pressurized gas leaks and electrical partial discharges in distribution networks and industrial environments. It fully complies with DL/T 1982-2019, DL/T 846.6-2018 and JJF 1496-2014 standards, adopting a high-density 64-channel MEMS digital microphone array and advanced beamforming algorithm to achieve reliable sensitivity and accurate sound source localization at an affordable price.
The instrument features a compact dual-function design that can detect both pressurized gas leaks (SF6, compressed air, nitrogen, etc.) and electrical partial discharges (corona, surface discharge) in a single scan. Its innovative adaptive intelligent noise reduction technology effectively suppresses ambient noise, enabling clear detection of weak acoustic signals in typical industrial environments. The real-time generated color acoustic cloud map is perfectly fused with the 5-megapixel visible light image, allowing operators to visually identify the exact location of faults at a glance. Equipped with an 8-inch high-resolution capacitive touch screen and intuitive graphical interface, it supports FFT spectrum analysis and basic partial discharge pattern recognition. With IP54 dustproof and splashproof rating, 1.5-meter drop resistance and ultra-light weight of only 1.2kg, it is ideal for all-day on-site inspections. Ideal for distribution network switchgear inspection, substation SF6 equipment leak detection, industrial pipeline leak troubleshooting, and compressed air system energy audit.
