The Technological Advantages of Dandong Tongda's X-Ray Diffractometers

X-Ray Generator System 

Dandong Tongda Science & Technology Co,.Ltd utilizes imported PLC control circuits instead of microcontroller (MCU) circuits, significantly reducing failure rates.

The use of imported Programmable Logic Controllers enables higher power output from the X-ray generator, meeting demands for high-power testing of special samples.

Competitors' systems using MCU-based control feature complex circuitry, numerous components, and high failure rates, with a key disadvantage being inability to maintain stable, long-term operation at high power levels.

The high-voltage control unit and management system achieve true electrical isolation (>2500V). The PLC module provides reliable management and real-time monitoring, with data displayed on a touchscreen interface.

All I/O interface modules employ optoelectronic isolation, ensuring complete electrical separation between the high-voltage generator's external circuits and the control system. Each module is shielded to prevent radiation interference

Recording Control System (Core Component) 

Using imported PLC control circuits instead of MCU circuits ensures more stable counting, simpler operation, and more compact structure.

The implementation of high-precision, automated Siemens PLC systems enables long-term, stable, fault-free operation.

Advantages over competitors' MCU-based systems:

Simplified circuit control with easy debugging and installation - comprising one Siemens PLC system and two highly integrated circuit boards

Software-based implementation of most functions (goniometer control, computer interfacing, X-ray generator operation, signal collection) reduces hardware complexity and failure rates

Modular design enables easy maintenance and debugging without requiring manufacturer technicians

Advanced true-color touchscreen interface with comprehensive protection functions and intuitive 3D animations for user-friendly operation and fault diagnosis

Enhanced counting stability improves overall system reliability

Easy expansion of functional accessories through PLC capabilities without additional hardware

Unique safety features: automatic voltage adjustment (e.g., 40kV/40mA to 30kV/20mA after testing), interlocked lead door/shutter system, and automatic safety shutdown/restart procedures

High-Performance Proportional Counter
