The system automatically controls the shutter switch, adjusts tube voltage and current, and includes an automatic X-ray tube training function. Real-time monitoring via a touchscreen greatly reduces operational complexity. Innovative Control, Revolutionary Operation Compared to traditional single-chip microcomputer circuits, the PLC control technology used in the TD-3500 offers multiple breakthroughs: Simple circuit control for easy debugging and installation Modular design allows users to perform maintenance and debugging themselves, significantly reducing costs Strong expandability for easy addition of various functional accessories without hardware modifications True-color touchscreen for human-machine interaction, user-friendly operation, and intuitive fault information display Precision Measurement, Safety Assured The TD series goniometer uses imported high-precision bearing transmission and is equipped with a high-precision full closed-loop vector drive servo system. The intelligent drive includes a 32-bit RISC microprocessor and a high-resolution magnetic encoder, capable of automatically correcting minute movement position errors to ensure high precision and accuracy of measurement results, with angular reproducibility reaching 0.0001 degrees. For safety, the TD-3500 adopts a hollow-axis structure with electronic lead door interlock装置, providing dual protection. The shutter window is linked to the lead door—when the lead door opens, the shutter automatically closes, ensuring comprehensive operator safety. Flexible Configuration, Comprehensive Compatibility The instrument offers two detector choices—proportional counter (PC) or scintillation counter (SC)—and multiple X-ray tube options including glass, corrugated ceramic, and metal-ceramic tubes, meeting different application scenarios and budget requirements.
