One Platform, Endless Insights: The Flexible XRD for Demanding Material Analysis
2025-12-23 13:21The core strength of the TD-3500 X-ray Diffractometer lies in its full-chain precise control and stable high-performance output. The instrument utilizes an imported Siemens programmable logic controller (PLC) system, enabling fully automated intelligent control from X-ray tube conditioning, tube voltage and current adjustment, to shutter operation. This ensures highly stable, fault-free performance over prolonged operation. Compared to traditional microcontroller-based control, this PLC system offers distinct advantages such as modular design, strong anti-interference capability, and ease of user maintenance and upgrades.
The "heart" of the instrument—the high-precision goniometer—adopts a hollow shaft design (protected by a National Invention Patent) and is equipped with a fully closed-loop vector drive servo system and a high-resolution magnetic encoder. This system monitors and automatically corrects minute positional errors in real time, achieving exceptional angular reproducibility and a minimum step angle of up to 0.0001°. This provides a fundamental guarantee for obtaining impeccable diffraction data.
To meet diverse and demanding application scenarios, the TD-3500 offers highly flexible configuration options. Users can select X-ray tubes with different target materials (Cu, Co, Cr, etc.) and various power ratings, as well as choose between glass, ceramic, or metal-ceramic tube types. Additionally, proportional or scintillation detectors are available to accommodate comprehensive analysis needs—from routine powder samples to specialized thin-film samples.
