Product Description

High Quality Powder X-ray Diffractometer


X-ray analysis equipments include x-ray diffractometer, x-ray crystal analysis equipment and x-ray crystal direction finder. The design of x-ray diffractometer (D series) is unique in China as it combines the advantages of programmable controller technique and ideas of module design. The application of triple non-intrusive isolation protection program gives the product with high performance, long life expectance and low frequency failure. The D series x-ray diffractometers are welcomed by many institutes, universities and other manufactories with its advanced controller, excellent data-processing software and accurate testing results.
In order to meet some special requirements for those users who involve in the production of titanium dioxide, our company specially developed the program focusing on the measurement of titanium dioxide. Through 3 times of continuous scanning to the samples, this program could measure the content of rutile in 4 types of samples (error range <0.2% ), including ilmenite, rutile, anatase and imported slag. 
1. X-ray Generator: 
Imported PLC control circuit is applied in lieu of single-chip control unit. This significantly reduces the equipment failure rate and increases the stability and reliability of equipment. Imported PLC programmable controller greatly improves the power of X-ray generator, which meets the special needs from some users who require the high-power X-ray generator for testing special samples. Compared with our products, the products from other companies are still using single-chip control unit, which makes the equipments with more complex structure and higher failure rate. The biggest drawback is that their equipments can not run stably in a long time at high-power scope (1.6KW and above). High-pressure control unit and the management system achieve the electrical isolation (isolating voltage> 2500V). The PLC module provides reliable management and real-time monitoring towards high-pressure control unit and the information is monitored by a real-time screen through the touch panel. As photoelectric isolation technology is applied in all I / O interface modules, so between the outside high-voltage generator circuit and control panel, the electrical isolation is really applied. For each of the modules, shielding measures are also used to prevent the radiation interference.
2. recording control system (the core of the diffractometer):
Based on the Philips technology, the diffractometer takes use of imported PLC (Programmable Logic Controller) control circuit instead of the original single-chip control circuit device. This improvement makes the instrument control system more stable, easier to control, and more structurally compact. The application of the imported Siemens PLC control circuit, which is of high degree of automation, ensures a longtime and stable operation of the whole system.
3. It owns the simple management for the circuits so that it is easy to debug and install. It only contains a Siemens PLC system and two highly integrated circuit boards. Besides, Most of the operations, such as rotating goniometric control, computer interface, X-ray generator control and signals collection, are controlled by software. This greatly simplifies the hardware system and reduces the failure rate of the system. Compared with ours, other diffractometers’ recording control systems are still using complex single-chip circuit, which makes debugging and repairing more difficult. Besides, their instruments have high failure rate and complicated structures. Most of their products contain 16 single-chips circuit board and some components, like integrated chips, are still taking Philips technology in 1970s. 
4. The system is very easy to maintain due to its modular design. Users can achieve the maintenance and debugging independently without the supervision of technical personnel. 
5. The use of advanced real color touch screen provides special functions, such as human-computer interaction, full protections and easy operations. The three-dimensional animation design makes the operating process more user-friendly and more intuitive. It is easy for operators to use the instruments and also, can help them to find useful information when problem happens.
6. It greatly improves the stability of the calculation system, thereby enhancing the comprehensive stability of the whole instrument.
7. The powerful extendable capacity of PLC can easily introduce many other multi-function attachments without applying additional hardware.
8. The instruments apply a unique high-voltage safety device to control the voltage during the process of sample testing. 

D-Series X-ray diffractometers are mainly used in the analysis of power, massive or film samples with their qualitative/quantitative attributes, crystal structure, material structure, crystal orientation, micro and macro stress, size of crystal and crystallinity.
