Product Introduction
The EMA600 is an open-architecture electromagnetic acoustic transducer (EMAT) testing module deeply customized for high-temperature and high-altitude industrial non-destructive testing (NDT) applications. It integrates high-temperature-resistant EMAT transducer technology with a compact electronic architecture, and is equipped with complete host PC software and UDP communication protocol. This enables integrators to rapidly equip robots, drones, and automated production lines with high-precision ultrasonic testing capabilities, truly achieving online inspection in high-temperature and high-altitude environments that are difficult to access using traditional methods.
The module can connect to EMAT probes, including conventional EMAT probes, high-temperature EMAT probes, small-diameter probes, etc. It is capable of inspecting materials such as carbon steel, stainless steel, and alloy steel. It can measure through coatings; the penetrable thickness depends on the EMAT probe. Currently, standard probes can penetrate approximately 6 mm. For other requirements, customization is available.
The module can be operated via the accompanying host PC software, which supports real-time data reception and processing, data saving in table format, and module configuration. Users may also develop their own host PC software, and we provide a software development demo for this purpose.
Core Features and Advantages
-
Extreme Environment Adaptability
Designed for high-temperature working conditions, paired with specialized heat-resistant probes and signal processing algorithms, it operates stably at workpiece surface temperatures up to +800°C without the need for couplant.
-
Modular Design
Modular architecture with complete electrical interfaces, mechanical dimensions, and underlying SDK. Supports user secondary development for specific scenarios such as pipeline elbow scanning and variable cross-section component inspection, making it easy to integrate into various automated testing platforms.
-
High-Speed Real-Time Communication
Utilizes UDP communication protocol for data transmission with high communication rates, ensuring real-time data feedback to the host PC with microsecond-level latency during high-dynamic flight or high-speed movement, without frame loss.
-
Adaptive Algorithm
Addresses common issues in robot/UAV deployment such as vibration, lift-off fluctuation, and non-perpendicular incidence with built-in adaptive algorithms, delivering stable and reliable A-scan signals and thickness data under non-contact, large lift-off conditions.
- Control and Analysis Software
Comes with feature-rich host PC software supporting measurement parameter settings, data reception and processing, real-time A-scan waveform display, C-scan imaging, and data export.
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.
