Description
The GDUI-511PD is a revolutionary, field-optimized dual-function acoustic imaging instrumentexclusively designed for non-contact, real-time detection and localization of pressurized gas leaks and electrical partial discharges. It fully complies with DL/T 1982-2019, DL/T 846.6-2018 and JJF 1496-2014 standards, adopting a high-density 128-channel MEMS digital microphone array and advanced beamforming algorithm to achieve ultra-high sensitivity and accurate sound source localization.
The instrument features a unique dual-function design that can detect both pressurized gas leaks (SF6, compressed air, nitrogen, etc.) and electrical partial discharges (corona, surface discharge, internal discharge) in a single scan. Its innovative intelligent noise reduction technology effectively suppresses ambient noise, enabling clear detection of weak acoustic signals even in complex industrial environments. The real-time generated color acoustic cloud map is perfectly fused with the 8-megapixel visible light image, allowing operators to visually identify the exact location of faults at a glance. Equipped with a 10-inch high-resolution capacitive touch screen and intuitive graphical interface, it supports FFT spectrum analysis, partial discharge pattern recognition, and leak rate assessment. With IP56 dustproof and splashproof rating, 2-meter drop resistance and ultra-light weight of only 1.8kg, it is ideal for all-day on-site inspections. Ideal for substation SF6 equipment leak detection, switchgear/GIS partial discharge inspection, industrial pipeline leak troubleshooting, and compressed air system energy audit.

FAQ
Q: What is the difference between GDUI-511PD and traditional gas leak detectors/PD testers?
A:
- Traditional detectors: Can only detect one type of fault, require close proximity to the target, and cannot visually locate faults
- GDUI-511PD: Detects both gas leaks and partial discharges in a single scan, works from up to 50 meters away, and visually displays fault locations with acoustic cloud maps It improves inspection efficiency by 100% and reduces equipment investment by 50%.
Q: Can it detect SF6 gas leaks from a distance?
A: Yes. GDUI-511PD can detect SF6 gas leaks as small as 0.5mL/s from 0.5 meters away, and can detect larger leaks from up to 50 meters away. This eliminates the need for close proximity to high-voltage equipment, greatly improving inspection safety.
Q: Can it distinguish between different types of partial discharges?
A: Yes. The instrument has a built-in partial discharge pattern library and can automatically identify common discharge types such as corona discharge, surface discharge and internal discharge based on the acoustic signal characteristics and frequency spectrum.
Q: Does it work in noisy environments?
A: Yes. GDUI-511PD adopts advanced adaptive digital filtering technology that can effectively suppress ambient noise by up to 30dB. It can obtain reliable test results even in noisy substations and industrial factories.
