Product Overview
The DT2022 is an open-architecture pulsed eddy current (PEC) testing module specifically designed for industrial non-destructive testing (NDT) in elevated working scenarios. Featuring a compact hardware architecture, open communication protocols, and supporting PC software, it provides integrators and R&D institutions with a "plug-and-play" high-performance electromagnetic testing core. It is widely applicable to robot-mounted inspections, drone patrols, and automated machine tool testing systems.
Core Features and Advantages
-
Open Architecture Supporting In-Depth Secondary Development
Provides complete hardware interfaces and software SDK. Users can customize testing logic and algorithms according to specific working conditions (such as complex curved surface tracking or high-temperature environment compensation), enabling rapid construction of dedicated testing solutions.
-
Optimized Design for Airborne Detection
Built-in adaptive filtering and signal stabilization algorithms address vibrations, attitude changes, and lift-off fluctuations inherent in airborne detection (robots/drones). This ensures high signal-to-noise ratio and measurement consistency under non-contact, dynamic scanning conditions.
-
UDP High-Speed Communication Protocol
Utilizes the UDP (User Datagram Protocol) for real-time data transmission with low latency and high throughput. This perfectly matches the high-speed scanning requirements of robots and drones, effectively avoiding blind spots caused by data packet loss.
-
Professional Supporting PC Software
The module comes with comprehensive PC-based control and analysis software. It supports real-time parameter configuration, waveform display, C-scan imaging, and data export, significantly lowering the debugging and validation threshold during the initial system integration phase.
Typical Application Scenarios
-
Robot-Mounted Inspection: Integrated into crawling robots or robotic arms for automated corrosion scanning of tank roofs and overhead pipelines.
-
Drone (UAV) Patrol: Lightweight design adapted for industrial drones, enabling non-contact rapid screening of elevated pipelines in petrochemical plants and bridge cables.
-
Machine Tool/Automated Production Line Integration: Embedded into CNC machine tools or automated workstations for 100% full-coverage quality inspection of workpieces or online equipment.
